Summary:      

On 6 February 2015, Production Coordinator Mr Taylor was injured when he was struck by a jib attachment on an integrated tool carrier, also known as an IT.

Mr Taylor and the IT operator had been attempting to manually extend the jib but a build-up of material prevented the jib from extending properly.

In an attempt to remove the material, the IT operator elevated the jib attachment so that it was hanging on an almost vertical angle. The IT operator began to gently shake the jib in an upward/downward motion so that the material would fall out. To assist in the process, Mr Taylor tapped the end of the jib with a sledge hammer.  Mr Taylor walked between the jib and the IT whilst the jib was being shaken in an elevated position. As Mr Taylor walked between the jib and the IT, the 322kg jib detached and struck his upper torso.
Mr Taylor sustained fractured ribs and compression fractures to two vertebrae.

Accused: Billabong Gold Pty Ltd (ACN: 613 900 922)

Incident Date: 28 April 2020

Mine Site: Plutonic Gold Mine approx. 150 kilometres from Meekatharra

Charge(s): Sections 9(1), 9A(2) and 15B of the Mines Safety and Inspection Act 1994

Summary: On 28 April 2020, two machine operators were working to change a loader bucket. The workers were inside the bucket and operating a hydraulic ram to insert a large pin. There was a loud bang and tooling from the configuration was ejected under pressure from the hydraulic ram. Both operators were both struck resulting in one operator suffering serious facial fractures and the other operator suffered a laceration to his forehead. Billabong Gold Pty Ltd had a safe work procedure (SWP) for the task. However, the SWP was manifestly inadequate because it failed to identify hazards associated with the task, the equipment and tools required for the task, and a process for installing the pins. The workers improvised an ad hoc configuration using a hydraulic ram. A job hazard analysis for the task was not completed and there was a lack of training and supervision resulting in a situation in which the workers exposed to a high risk of serious injury.

Billabong Gold Pty LTD pleaded guilty and accepted responsibility for the incident.

Accused: Central Norseman Gold Corporation Pty Ltd (ACN 005 482 860)

Incident Date: 15 February 2014

Mine Site: Harlequin Gold Mine

Charge(s):

Mines Safety and Inspection Act 1994, sections 9(1) and 9A(2)

Summary:

On 15 February 2014, Mr Fowlie was killed by falling rock while he was working underground at the Harlequin Gold Mine.

Mr Fowlie had been assigned to remove ore rock, using a bogger, from around the face of the 203 East drive, which had been blasted the previous day. At some stage he dismounted from the bogger, apparently to remove some loose rock from the tunnel face. His body was discovered, about six metres back from the tunnel face, buried under a several tonnes of rock which had fallen on him. Mr Fowlie died of serious crush injuries and asphyxiation resulting from the rockfall.

The accused admitted that it had committed an offence by failing to ensure that adequate ground controls had been installed in the drive and that, if they had been installed, the rockfall that killed Mr Fowlie would not have occurred. In particular, an insufficient number of rock bolts had been used to support the rock near the face of the drive where the conditions for rock stability were poor.

The accused also admitted that it had failed to implement an adequate geotechnical programme for the purpose of ensuring that ground controls in the drive were competently reviewed and adapted to changing ground conditions.

Accused: DKMSPP Pty Ltd  (ACN 093 318 613)

Incident Date: 11 July 2012

Mine Site: Newmont Boddington Gold Mine

Charge(s): Mines Safety and Inspection Act 2004, s. 12(2)(b) and s.12A(2).

Summary:

Mr Mostert was working as part of a day shift crew conducting the reline of Ball Mill 3.  That work involved the removal of old liners and their replacement with new ones.

Liners were knocked in from outside the ball mill but two liners remained stuck.  These were to be removed from inside the ball mill.

None of the safe work procedures specifically addressed the removal of stuck liners. The Job Safety Analysis that was prepared did not articulate specifically step-by-step the procedure required to remove the unsecured liners and specifically identify the hazard or the controls necessary to ensure a worker did not work or stand in close proximity to unsecured liners and there were no specific physical or mechanical aids provided that eliminated exposure to the hazard.

Mr Mostert was working under and next to the unsecured liners when the top unsecured liner fell on Mr Mostert resulting in significant crush injuries.

The accused pleaded guilty to Charge 1 (CO564/2015) on the basis of the following particulars:

The hazard was unsecured shell liner plates falling from inside the ball mill shell while workers were in the ball mill in proximity to the unsecured liners.

The system of work being operated by the Accused was the relining of Ball Mill 3 at the Mine, including removing shell liners from the ball mill.

The practicable measure the Accused failed to take on 11 July 2012 was to ensure Mr Mostert did not work or stand in close proximity to an unsecured shell liner on the inside of the ball mill shell.

The serious harm caused bodily injury to Mr Mostert of such a nature as to endanger life.

Charge(s): Mines Safety and Inspection Act 1994, section 13(A)(3)

Summary:

A tank, which was part of the Atmospheric Leach Plant at the Mine, ruptured and collapsed during operation and released approximately 2 million litres of slurry containing 1.58% free sulphuric acid at 101.35°C.  The wave of slurry destroyed the tank, moved infrastructure, and dismounted transformers, cutting electrical supply. Three employees inside a utilities control room situated 40 – 50 metres behind the tank, escaped without injury.

The internal lining of the tank had failed and holes were identified in the tank wall in work lists dated 30 September 2014, 26 November 2014 and an ongoing work order. The holes remained unrepaired for at least 2.5 months. Slurry escaped and travelled down the outer steel shell corroding the outer steel shell and as a result, the tank ruptured. The escape of the slurry posed the risk of burn injuries and/or the potential for injury or death by impact of equipment or plant moved by the slurry.

The accused pleaded guilty to failing to take the following practicable measures:

Failing to inspect and/or test the atmospheric leach tank in such manner as would have determined the extent to which its condition had been impaired.

Failing to ensure that the atmospheric each tank was maintained n such condition that it was not susceptible to rupture during operation.

Incident Date: 25/05/2013

Mine Site: Karara Iron Ore Project, approx. 220km east of Geraldton

Charge(s): Mines Safety and Inspection Act 1994 - Section 9(1) & 9A(2)

Summary:
A team of workers were attempting to jack apart a screen box using an Enerpac Jack abutting a scaffold bar. The scaffold bar was under high pressure. It struck and seriously injured Mr Martino as it was not securely attached to the jack. A job step hazard and control analysis (JHA) was developed that did not address the use of an Enerpac and a scaff tube. Site requirements for JHA’s were not enforced. The tools were not designed for that purpose, the Enerpac was not used in accordance with OEM instructions. Three workers entered the box without a confined space permit. The offending was serious but was mitigated by the very early plea (for which a discount of 25% was given), cooperation, and the absence of prior convictions. His Honour noted that the penalty had to send a message to other employers that Safety is Paramount.

Accused: Karara Mining Ltd (ACN 070 871 831)

Incident Date: 3 August 2015

Mine Site: The Karara Iron Ore Project

Charge(s):  Mines Safety and Inspection Act 1994 section 9(1)

Summary:
A 120 tonne capacity gantry crane was driven into an Elevated Work Platform (EWP) with two of Karara’s electricians working in the basket 12m high. The electricians were shaken, but escaped without injury. They were not thrown from the basket, and managed to lower it to the first floor of the building. There was no communication between any of the different workgroups operating in the area. The crane was remotely operated and the operator was out of sight of where the base travelled on the rail.

The accused had a detailed set of written procedures, but it failed to ensure that workers on that day adhered to written procedures. Each of the three workers directly involved in the incident failed to comply with their written hazard control processes. The crane operator did not check the area around the crane, the two electricians didn’t use a spotter or barricades.

After the incident, a fixed barrier was erected around the rail.

The company entered a plea of guilty at the first opportunity and received a 25% reduction from the head sentence of $60,000, with further reduction for other mitigating features (to $40,000).

Mine Site: Karara Mine, approx. 200km East of Geraldton and 320km North of Perth, WA

Charge(s): Sections 9(1) and 9A(2) of the Mines Safety and Inspection Act 1994

Summary: On 21 January 2019 a process operator at the Karara Mine processing plant was tasked with hosing off the upper proximity sensor on a dart value which was one of three dart valves that controlled the flow for the tailings filter feed tanks. The process operator put his hand into the unguarded section at the top of an adjacent dart value which spontaneously operated to open and trapping his hand. It was practicable for the Offender to have taken the following measures: Installed physical guarding preventing access to the danger point while the dart valve was operating; and labelled each of the dart valves such that any person nearby was able to identify each one from any other and ensured that employees all used the terminology on the particular label to identify each dart valve.

This is Karara Mining Ltd’s third offence of the Mines Safety and Inspection Act 1994.

Summary: On 13 July 2020, a mine worker fell into an open stope (hole in underground mine) while operating an underground loader (bogger), a fall distance of approximately 25 metres and suffered fatal injuries. The offender was the underground shift supervisor at the mine who failed to take reasonable care after instructing the worker to build a bund in close proximity to an open hole hazard. The offender removed a barricade after instructing the mine worker to meet him at the 2075 level for the purposes of building the bund. The offender also left the 2075 level for a period of time during which time the entrance to the open hole there was unattended by any person acting as a sentry and unprotected by any physical barrier.

Charge(s): Sections 9(1) and 9A(2) of the Mines Safety and Inspection Act 1994

Summary: On 18 May 2017, a worker suffered third degree burns over his hand and wrist, a fractured forearm and a laceration when his right arm was pulled into a nip point on a conveyor system on a shell bagging machine. The shell bagging machine was being repaired by two workers who removed the guarding each side of the conveyor. One worker completing the repair and walked away. While the machine was still unguarded and had not been locked off to prevent operation, the victim turned it on in order to check the conveyor belt had been adjusted correctly. He slipped and fell on the conveyor drawing his arm into it and he had to be cut free.  Two days after the incident the offender installed a lockable emergency stop device (ESD) to the shell bagging machine. The ESD’s purpose was to ensure that the machine remained off during maintenance work.

Accused: Limestone Building Blocks Company Pty Ltd (ACN 009 252 608)

Incident Date: 25 January 2017

Mine Site: The Limestone Building Blocks Company Site, Nowergup

Charge(s):

Mines Safety and Inspection Act 1994, sections 9(1) and 9A(2)

Summary:

On 25 January 2017, Mr Smith, a labourer employed by LBBC, was seriously injured at the Plant when he became entangled in the machinery of a block-making machine.

Mr Smith had entered the block-making machine through the gate of a guard mounted on one side of it, in order to attempt to extract a large lump of dry limestone aggregate from the feed tray of the machine. At the time, the block-making machine was set to operate in automatic mode. As Mr Smith entered it, a part of his body triggered a sensor that caused the machinery to perform a block-making cycle while he was trapped inside.

During the Incident, Mr Smith’s right foot was severed above the ankle, and he sustained fractures to his spine, pelvis, ribs and left leg and internal organ damage.

The accused admitted that it had failed to maintain an adequate system of ensuring that the machinery inside the guards of the Block Machine did not operate while any person was working inside them. A reasonably practicable method of doing so would have been to maintain the Captive Key Interlock Safety System described in the manufacturer’s Operation and Parts Manual for the Block Machine. That system specified the issue of a single key that could be used either to switch on the hydraulics that powered the machinery, or to open the guards, but not both at the same time.

The accused conceded that maintaining such a system would have prevented the incident that injured Mr Smith.

Incident Date: 29 December 2013

Mine Site: Maintenance workshop at Christmas Creek Mine

Charge(s): Mines Safety and Inspection Act 1994, s9(1) and 9A(3)

Summary:

Mr Zuvela was killed and Mr Reid was seriously injured at the Global Surface Mining maintenance workshop at Christmas Creek Mine. 

The two workers were installing a cab in a surface mining machine after a rebuild. The cab has a mass of about 2.5 tonnes and was suspended from an overhead crane.  Contrary to safe work practice, both workers were positioned in the path of the cab as it swung down.

A failure occurred in the rigging arrangement between the cab and the overhead crane.  There was no detailed safe work procedure for the cab installation.

MesaWest failed to provide a safe work environment by failing to take reasonable steps to develop a specific procedure for the Task, or in the absence of a specific procedure, to ensure that employees would conduct a JHA, or sign on to an existing JHA approved by a supervisor.

Incident Date: 12 April 2015

Mine Site: Miitel Nickel Mine

Charge(s): Mines Safety and Inspection Act 1994, section 9(1) and 9A(3)

Summary:

On 2 April 2015, a surveyor was reversing a ute down an underground access tunnel towards an open stope. The surveyor was on his way to conduct a cavity monitoring survey to determine the dimensions of the stope. While reversing the ute, he was looking for an “open stope below” sign which he believed to be approximately 30 – 50m from the edge, where he intended to stop and set up the survey equipment. The surveyor reversed the rear wheels of the ute over the edge of the stope.  He avoided plummeting into the stope by applying the brakes until he was rescued by fellow workers.  The fall from the lip of the stope was 19 metres.

At the time of the Incident there was no adequate system of work in place in relation to the placement of signs near open stopes in single entrance headings and there was no bund secured at the edge of the open stope. A bund would have prevented the surveyor reversing over the edge, and it was a practicable engineering control measure that would have prevented the Incident.

Charge(s): Sections 15A, 9(1) and 9A(2) of the Mines Safety and Inspection Act 1994

Summary: On 13 July 2020, a mine worker fell into an open stope (hole in underground mine) while operating an underground loader (bogger), a fall distance of approximately 25 metres and suffered fatal injuries.  Northern Star (Carosue Dam) Pty Ltd was the principal employer at the mine. It had contracted with Byrnecut Australia Pty Ltd for Byrnecut to provide underground works at the mine. Northern Star asked Byrnecut to build a bund (rock wall) close to the edge of the stope so that a surveyor could conduct a Cavity Monitoring System Survey, a survey of the stope using electronic equipment. Northern Star did not conduct a Job Hazard Analysis or ensure necessary safety measures were in place to ensure that the Byrnecut mine worker could safely build the bund.

Incident Date:16 November 2015

Mine Site: Paulsens Gold Mine

Charge(s): Mines Safety and Inspection Act 1994, section 13 and 13A(2)

Summary:

An underground jumbo’s off-sider, Mr Perttula, collapsed while working on a development heading approximately 900m below ground. He later died of heat stroke/exhaustion.
Northern Star admitted that it had failed to maintain the ventilation system in the mine, had not taken measurements to determine the conditions of the working environment before work commenced and failed to enforce procedures for the modification or stop of work in excessive heat and humidity.

The Magistrate noted in sentencing that Northern Star was aware of the hazard and of the serious consequences which might flow from exposure to extreme heat. He found that the exposure arose in the ordinary course of operations and arose across the entire workings of the mine. He noted that the ventilation system was not properly maintained, nor were Northern Star’s own policies regarding heat adequately implemented. The hazard that caused the fatality was well known, serious, preventable, and arose in the ordinary course of Northern Star’s operations. In imposing the penalty, the Magistrate also took into account that Northern Star pleaded guilty at an early stage, cooperated, expressed remorse, and improved safety procedures following the incident. A discount of 25 per cent was given for the plea of guilty at the earliest opportunity.

Summary:   

On 31 October 2012 Mr Garcia was injured when he fell from on top of a load of pipes being unloaded from a truck at the Woodie Woodie tailings processing plant.  He was involved in rigging the pipes (which weighed over 1 tonne each) from the back of truck.  He was attaching slings to each pipe prior to it being lifted by a crane.  He was struck in the abdomen by a pipe as it was being raised from the truck and was thrown backwards falling approx. 4 metres, breaking his arm and suffering severe bruising to his back and hip.  The principal employer at the mine was Process Minerals International Pty Ltd and they had engaged Mr Garcia to perform the task. The same task had been conducted in the same way 6 days earlier on 25 October 2012 but had not resulted in any injury on that occasion.

There was no appropriate procedure in place for this type of task, and no proper risk assessment (job hazard analysis) done.  The site did not have the appropriate equipment for the safe unloading of trucks. There are safe methods available for this type of activity and other sites have procedures for similar tasks.

Incident Date: 13 September 2014

Mine Site: Cloudbreak Mine

Charge(s): Sections 9(1) and 9A(2) of the Mines Safety and Inspection Act 1994

Summary:  

On 13 September 2014 an employee of Rema Tip Top, was seriously injured when struck by the hook of a come-a-long during the changing of a return roller on a conveyor belt system at Cloudbreak Mine. As a result of being struck in the face by the hook on the come-a-long, the worker suffered a broken jaw and damaged teeth. These injuries require long term chronic pain suppressant.

Rema Tip Top was engaged at the mine to undertake maintenance services including conveyor system maintenance.

Rema Tip Top failed to adequately instruct workers on how to replace the return roller. In particular, it failed to instruct never to back-hook a come-along and on how to replace a return roller, including how to safely lift the conveyor belt. It did not provide adequate supervision, by means of a job hazard analysis, or ensuring that workers were monitored by a competent person to ensure that the work was carried out safely.

While the company had systems of safety in place and the injured worker was a qualified dogger, there was a lack of training for the task of changing a return roller. The company pleaded guilty at an early opportunity.

Incident Date: 20 January 2015

Mine Site: Woodie Woodie Manganese Mine

Charge(s): Mines Safety and Inspection Act 1994, section 9(1) and 9A(2)

Summary:

The fatality occurred when a fitter, Mr Kitching who was employed by the Accused, was attempting to remove a belly plate from a Komatsu 275 dozer to clean out mud that had accumulated there and was causing the dozer to overheat.  The belly plate fell and crushed Mr Kitching. The dozer was being used to clear land in preparation for exploration activities. 
 
The Accused was sentenced on the basis that it had failed to enforce a system so that damage to the belly plate was reported and communicated to employees and that it had failed to implement a safe system of work for the removal of the belly plate. The sentencing magistrate also found that the level of supervision provided by the Accused was a factor which raised the risk of a serious problem arising and so increased the seriousness of the offence.

Accused: Sandfire Resources Limited (A.C.N. 105 154 185)

Incident Date: 21 May 2020

Mine Site: DeGrussa Copper Mine, north-east of Meekatharra

Charge(s): Sections 13 and 13A(3) of the Mines Safety and Inspection Act 1994

Summary: On 21 May 2020 an underground explosives operator at the mine site was working from an elevated basket attached to a ‘charge-up vehicle” when the ground above him collapsed. The rock fall pushed the basket of the charge up vehicle down to the ground and trapped the operator inside. He had rocks pushing down on him, he could not move and had difficulty breathing. The operator suffered scratches and lacerations and was fortunate to not have incurred more serious injuries.  Underground mining requires detailed analysis of the rock structures and planning in accordance with accepted safety factors that are designed to ensure that tunnelling and blasting rock to remove ore is safe for persons working underground. Concerns about the integrity of the ground had been communicated to Sandfire by workers in the days prior to the rock fall. Remedial measures to rehabilitate the ground support in the area were implemented in response. However, these rehabilitation measures were inadequate as they were designed based on inaccurate information and did not take account of significant geological features in the area. Work to update the geological structural modelling used for ground support assessment had been undertaken in the months prior to the incident. However, the updated structural models were not communicated to Sandfire’s geotechnical engineers responsible for the ground support due to gaps in Sandfire’s processes for validating structural models and communicating updates to technical personnel.

Sandfire by its plea has admitted that it failed to take the practicable measures to avoid the hazard.

Summary:  

On 17 April 2014 at the Tuckabianna Processing Plant, approximately 25km south-east of Cue a boilermaker was seriously injured while conducting maintenance on a jaw crusher. As part of regular maintenance, the jaw crusher’s liners are periodically replaced. It was while trying to fit the liners that one of them fell. The liners weighed between 1.8 and 2.3 tonnes. The workers were having difficulty fitting the liner into position. A piece of timber was used as a wedge to hold the liner in what they thought was the correct position.  While the liner had not yet been bolted in, the victim believed it was sufficiently imbedded in its inclined position that it could not fall forward.  It was after the timber wedge was removed in order to start positioning the next jaw liner that the first liner fell and injured the victim. The victim suffered extensive injuries as a result.

Charge(s): Mines Safety and Inspection Act 1994, sections 9 & 9A (2)

Summary: 

On 29 September 2014 two Electricians were deployed to check the outer doors of a lift at ground level of the Refinery’s Powerhouse as they were not closing and the lift could not be operated. The Electricians bypassed the safety circuit to get the lift to override the fault and allow them to move the lift. One of the Electricians travelled down in the lift to check if the doors on the ground floor were still open, while the other Electrician remained in the control room at the top of the lift. It is not known what the Electrician was doing just prior to his death, however he was found deceased, having been crushed between the lift car and the lift shaft.

The Magistrate was particularly concerned with the failure of the company to enforce safety procedures, describing the safety system as so fractured as to not really be a system at all.

Summary:

Breach of Regulation 6.22(b)

The Accused undertook drill and blasting services at the Mine.

On 2 January 2015, a Mobile Manufacturing Unit (MMU) had a flat tyre. While it was being reversed into the workshop, the second in charge Drill Supervisor (‘2IC’) heard air escaping from the MMU. He inspected the vehicle and found that a rubber diaphragm in a box behind the cab of the vehicle had split causing the air to leak. The split diaphragm was a “brake regulator diaphragm” which sat within the quick release valve and was part of the air brake system on the MMU.

The 2IC did not know what the split diaphragm was but proceeded to make a replacement diaphragm by cutting a piece of rubber into the shape of the split diaphragm and replacing it in the quick release valve.  He was not qualified to competently repair or modify the brakes.

The Accused pleaded guilty to a failure to ensure that inspection and repair to the brakes on a Mobile Manufacturing Unit was carried out by a competent person.
