3 In the proceedings now before me, the prosecution has tendered an agreed statement of facts. The agreed statement of facts are as follows:
[1] Claim 26313 located at Dead Bird, Coocoran Opal Fields outside Lightning Ridge, is the place where Mr Peter Buchanan was engaged in mining operations seeking to discover opals.
[2] Mr Peter Buchanan was entitled to conduct such mining operations as a consequence of permission being granted by the claim holder, Eureka Opals Pty Ltd.
[3] Up until 1997 some of the equipment utilised at the mine including the pelican picks, blower and compressor was owned by Eureka Opals Pty Ltd.
[4] Mr Peter Buchanan entered into an arrangement with Mr Anthony Kennedy in which Mr Kennedy was to receive 10% of the value received by Mr Peter Buchanan for opals jointly discovered by Mr Peter Buchanan and Mr Anthony Kennedy at Claim 26313.
[5] Mr Anthony Kennedy had commenced working with Mr Peter Buchanan shortly before Christmas 1999. Mr Kennedy, prior to working with Mr Peter Buchanan, had only limited experience in performing mining work. Mr Peter Buchanan was aware, however, that Mr Kennedy had undertaken some opal mining work with his father in the Lightning Ridge area.
[6] Specifically, Mr Kennedy, prior to working with Mr Peter Buchanan, had not undertaken the Lightning Ridge Safety Awareness Program Mining Course, which was made available by the Department of Mineral Resources in the Lightning Ridge area at the relevant time.
[7] Mr Peter Buchanan instructed Mr Kennedy on a day-to-day basis as to the work he was to perform. The work performed by Mr Kennedy was primarily:
(i) Digging;
(ii) Cleaning up material excavated.
[8] It is the nature of opal mining in the Lightning Ridge area that a 3-foot diameter shaft is drilled from the surface to a point in the subsoil where opal bearing clay bands are found. Further, access down the shaft hole is obtained by ladder. Once at the base of the shaft hole excavation of the deposit bearing clay band commences. The material excavated is brought to the surface via a vacuum/blower pipe where it is mechanically sorted. As the excavation continues the roof is secured by the use of rock bolts, or more usually, timber props. The placement of such timber props, the number of props and the pattern of placement is subjectively determined by the miner having regard to the geological nature of the material being excavated, any visual signs of roof decay or instability and knowledge of the prevailing geological formations in the area.
[9] The Dead Bird field was known to be geologically dangerous with a high rate of roof collapse due to the geology of the field. This had resulted in a number of serious injuries and fatalities in the past.
[10] Claim 26313 had four 3 foot shafts and several 14 inch holes which all joined underground. One shaft was used for access, egress, placement of service pipes as well as the placement of the blower tube. It is recommended by the Department of Mineral Resources that a second shaft be used to accommodate the services leaving the main shaft free for access and egress.
[11] Photographs taken at or around 28 March 2000 showed that prior to reaching the area where Mr Kennedy was injured a series of timber props had been put in place to support the roof. As at 28 March 2000, a ballroom excavation had taken place. This excavation meant there was approximately 5.5 metres of unsecured roof.
[12] On 28 March 2000 Mr Peter Buchanan and Mr Kennedy entered the mine. Mr Peter Buchanan conducted a visual inspection of the roof and concluded that it was safe to work under. Mr Peter Buchanan did not discuss the state of the roof with Mr Kennedy.
[13] Mr Peter Buchanan had instructed Mr Kennedy to work in the ballroom area breaking up lumps of toe dirt. He was further instructed by Mr Peter Buchanan to feed dirt into the blower pipe so that the dirt could be removed to the surface. Mr Peter Buchanan was engaged at the relevant time in unblocking a bend in the blower pipe when he noticed a lump of dirt landing near him. Mr Peter Buchanan on noticing the lump of dirt further checked the roof, did not see any movement and told Mr Kennedy to continue to feed the dirt. On inquiry from Mr Kennedy, Mr Peter Buchanan stated that there was only about five more minutes to complete this part of the job.
[14] It was intended that after the area had been cleared and the blower pipe moved that Mr Peter Buchanan and Mr Kennedy would then install up to six roof props in the area in which Mr Kennedy was working.
[15] After Mr Peter Buchanan informed Mr Kennedy that there was only five minutes to go to finish the job, Mr Peter Buchanan looked at the roof where he observed a crack of 1 or 2 inches opening up. Mr Peter Buchanan yelled out a warning to Mr Kennedy. Mr Kennedy responded by trying to move out of the area but he was struck by the fall of roof. Mr Kennedy was not wearing a hard hat at the time as he had lost it up the blower pipe the previous day. Mr Kennedy's body was covered from the waist down with pieces of sandstone that had fallen from the roof. Mr Peter Buchanan went immediately to Mr Kennedy at which time Mr Kennedy requested that Mr Peter Buchanan remove him from under the unsupported roof. Mr Peter Buchanan dragged Mr Kennedy out of the area of immediate danger.
[16] There was no method of communication within the mine for communicating from the mine to the surface. Mr Peter Buchanan exited the mine and sought assistance from his brother, Mr Wayne Buchanan. He found Mr Wayne Buchanan working some short distance away and informed him of the need for assistance.
[17] Mr Wayne Buchanan followed Mr Peter Buchanan down into the mine and assessed the injuries to Mr Kennedy. Mr Wayne Buchanan then came back to the surface, spoke to a Mr Pace, and inquired whether Mr Pace had a mobile phone. Mr Pace did not. Mr Wayne Buchanan then drove to a place known as the Smoko Van and sought to use their telephone. This was unsuccessful. Mr Wayne Buchanan then saw a Mr Cree. Mr Cree said that while he had a telephone, he did not bring it to work that day. Mr Wayne Buchanan went back to the Smoko Van and spoke to a Mr John Venning. Mr Venning finally managed to contact Emergency Services and inform them of the situation.
[18] Mr David Lane, the local SES Controller, arrived at the scene. Mr Lane descended into the mine noticing that the ladders in the shaft were not pegged into place but were swinging. Once Mr Lane had determined that the area was safe enough for Ambulance Officers to be able to attend, those Ambulance Officers descended into the mine. In doing so they complained to Mr Lane about the instability of the ladders and the lack of space available in the shaft due to the presence of services and the blower tube. There was another shaft 26 metres away but that shaft did not have ladders in at the time. Mr Lane had the Ambulance gear lowered down the shaft. The Ambulance Officers made an assessment of Mr Kennedy. This assessment was that he was suffering from life threatening injuries and needed emergency evacuation. Mr Kennedy was unable to be evacuated out of the mine using the main access shaft because it was cluttered and because the ladders were not fixed. Mr Lane therefore sought to identify an alternate exit. Mr Lane travelled underground until he reached an adjoining mine and located an exit shaft that could be used. Mr Kennedy was then strapped to a stretcher and was carried over 30 metres or so of tunnels until the exit shaft was reached. He was then transported up the exit shaft and into a waiting ambulance. There were other shafts available at Claim 26313 that Mr Kennedy could have been evacuated out of. The closest of these was 26 metres away from where Mr Kennedy was injured. Mr Kennedy was later transported by Air Ambulance to the Prince of Wales Hospital in Sydney.
[19] Mr Kennedy's injuries were found to be:
