Proceedings of the 2003 Coal Operators' Conference

2003

The underground coal operators conference series held annually in Wollongong has been recognised as the main form of the exchange of ideas between the mine operators, engineers and researchers in the diverse field of coal mining technology. For the last five years the conference addressed a variety of issues, focusing primarily on underground ground control and mine safety. In order to increase participation, the attention has now been drawn to addressing various issues in addition to ground control and the theme of Coal2003, Longwall Environment demonstrates the true interest of the conference in promoting high output longwall operation. This year the conference is preceded by a halfday workshop on mine subsidence.

Proceedings of the 2010 Coal Operators' Conference

2010

after two years it began once aging in 2001, as a gathering of a select group of people focusing on the Australian Coal Mining Industry operations and achievements. The 2001 colloquium was a one day event, which was held as a tribute to late Dr Alan Hargreaves, for his pioneering role in both gas and geotechnics in the Australian Coal Mining Industry. There were a total of 11 papers with some 75 participants. A year later in February 2002, a two day conference was held at the University of Wollongong, this time as a tribute to Dr Ripu Lama for his expertise in geotechnology and outburst management. There were a total of 22 presentations made over the two day conference which was preceded by a half day seminar on mine gas and outburst management. This event continued in Wollongong in 2003 and In 2005 the venue of the conference was moved to Brisbane and some 40 papers were presented during three days conference. At that conference the delegates were provided with a CD in addition to the conference proceedings. The CD also contained papers from the past four conferences. In 2006, the conference was held in Wollongong and there was no conference held in 2007. Since 2008 this has become an annual event held at Wollongong. The decision to hold the conference annually with Wollongong as the venue was based on a survey conducted in 2008.

Proceedings of the 2004 Coal Operators' Conference

2004

The underground coal operators conference series held annually in Wollongong has been recognised as the main form of the exchange of ideas between mine operators, engineers and researchers in the diverse field of coal mining technology. For the last five years the conference addressed a variety of issues, focusing primarily on underground ground control and mine safety. In order to increase participation, attention has now been drawn to addressing various other issues in addition to ground control. The theme of Coal2004, Mine Planning demonstrates the true interest of the conference in promoting high output longwall operation. This year the conference is preceded by a halfday workshop on mine subsidence and surface environment impacts.

Proceedings of the 2014 Coal Operators' Conference

2014

On behalf of the organising committee I welcome you to the 14 th Coal Operators Conference (Coal2014).The duration of the conference has been extended for three days because of the increasing number of good quality and innovative papers presented. 42 papers out of a total of 49 will be presented on topics covering both surface and underground mining, and includes papers on geology, geophysical logging, geotechnical engineering, rock fracture mechanics, general ground control, heading development, longwall mining, pillar design, information technology, rock cutting and rock bolting, mine ventilation, mine gases and fugitive gas emissions, outburst control, mine safety and risk management. A number of Australian mine operators, consultants, research organisations and academics are show-casing their cutting edge research findings in the conference.

Proceedings of the 2011 Coal Operators' Conference

2011

Mining commenced at Tasman Mine in late 2006. The current method of mining is bord and pillar using continuous miner-bolters and shuttle cars for first workings and secondary extraction using breaker line supports. The two stage process was chosen to accommodate irregular shaped coal deposits, allowing adjustments to be made to extraction ratios for better management of subsidence and to maximise the efficiency of the operation. Following the completion of the first three full/partial extraction panels a change in mining method was undertaken due to variable caving. The adopted partial extraction method involves stripping the developed square pillars on four-sides on retreat to leave a load-bearing remnant coal pillar. The system of partial extraction has been successful in delivering safety, productivity and subsidence targets.
