Rapid Rating Using Coal Mine Roof Rating To Provide Rapid Mine Roof Characterisation From Exploration Drilling, J. Calleja
Resource Operators Conference
The Australian coal industry is currently experiencing rapid expansion with many companies fast tracking the development of new mines. In many cases, operators are collecting large quantities of exploration drilling data for pre-feasibility and feasibility studies as well as for operational start-up and mine expansion. “Rapid Rating” is a new method for calculating the Coal Mine Roof Rating (CMRR). It has been designed to allow large quantities of exploration data to be processed quickly to provide a standardised indicator of geotechnical conditions. It is intended to make CMRR more readily available to mine operators. When the CMRR was first developed …
Why Uniaxial Compressive Strength And Young's Modulus Are Commonly Poor Indicators Of Roadway Roof Stability - Except In The Tailgate, M. Colwell, R. Frith
Why Uniaxial Compressive Strength And Young's Modulus Are Commonly Poor Indicators Of Roadway Roof Stability - Except In The Tailgate, M. Colwell, R. Frith
Resource Operators Conference
For many years underground rock mechanics and in particular, roadway/tunnel roof stability has been underpinned by the often unchallenged assumption that roof strength (as defined by the UCS) and stiffness (E) are key stability controls. This has logically led to the proliferation of laboratory testing of rock specimens and the development of indirect geophysical methods to gain estimates of these two rock parameters. Furthermore, many design methods are significantly focussed on replicating rock mass behaviour through either intact or failed constitutive models. Demonstrably the strength and stiffness of the host rock material is commonly used as one of the key …
A New Real Time Personal Respirable Dust Monitor, A. D. Gillies, H. W. Wu
A New Real Time Personal Respirable Dust Monitor, A. D. Gillies, H. W. Wu
Resource Operators Conference
A new personal respirable dust monitor developed by Thermo Electron Corporation under a project funded by the US National Institute of Safety and Health (NIOSH) has generated promising results in underground coal mine testing performed in the US recently. An Australian Coal Association Research Project funded study has been undertaken to evaluate this new real-time dust monitor for personal respirable dust evaluation use particularly in engineering studies. It is believed to be the first personal dust monitor instrument (PDM) for use on mine faces that reliably delivers a near-real-time reading. It can quickly highlight high dust situations and allow the …
An Integrated Real-Time Roof Monitoring System For Underground Coal Mines, B. Shen, H. Guo, A. King, M. Wood
An Integrated Real-Time Roof Monitoring System For Underground Coal Mines, B. Shen, H. Guo, A. King, M. Wood
Resource Operators Conference
CSIRO has been conducting a five-year research project under the sponsorship of JCOAL and Ulan Mine to develop a real-time roof monitoring and roof fall warning system for underground coal mines. A preliminary system has been developed and successfully trialled twice in the gateroads at Ulan Mine during 2004 and 2005. The system integrates the displacement monitoring, stress monitoring and seismic monitoring in one package. It includes: • GEL multi-anchor extensometers • Vibrating wire uniaxial stress meters • ESG seismic monitoring system with microseismic sensors and high frequency AE sensors. The monitoring system has been automated and the data are …
Observations On The Variation In Acoustic Emissions With Changes In Rock Cutting Conditions, E. Williams, P. Hagan
Observations On The Variation In Acoustic Emissions With Changes In Rock Cutting Conditions, E. Williams, P. Hagan
Resource Operators Conference
The emission of acoustic signals or micro seismic activity in rock subjected to stress is a well established phenomenon that has been exploited in geomechanics for example to understand changes in stress levels around excavations in active mine areas. Another potential application is in the area of rock cutting. The finding of a study to investigate whether changes in rock cutting conditions are reflected in the nature of acoustic signals generated in rock is presented. A test facility was established comprising a linear rock cutting machine, acoustic transducer and data acquisition system. The study examined changes between a new and …
Airborne Geophysical Techniques, M. Armstrong, A. Rodeghiero
Airborne Geophysical Techniques, M. Armstrong, A. Rodeghiero
Resource Operators Conference
Airborne geophysical surveys have been used extensively in the mineral exploration industry predominantly for the delineation of metalliferous deposits. Recent advances in technology and the integration of multiple geophysical data-sets including aeromagnetic, radiometric and gravity surveys can provide useful information on lithology and structure. Additionally advances in data analysis, processing and image enhancement techniques have improved the resolution of geophysical datasets so that very subtle variations in the geophysical responses can be identified. High resolution aeromagnetic and radiometric surveys have recently been acquired over the Dendrobium mine district in the Illawarra Coal Fields. The primary objective of this survey was …

Advances In Surface Seismic Acquisition, Processing And Interpretation, A. Rodegheiro, L. Fredericks
Resource Operators Conference
Seismic Reflection surveys and borehole drilling have been the two primary exploration tools used in Illawarra Coal’s operations in the Southern Coalfield. For the past 10 years the exploration department has been using their in house acquisition system developed by BHP. However, this system was limited to 180 channels and two dimensional surveys and a more advanced system was required with a much larger channel capacity for modern three dimensional seismic surveys. In July 2004 Illawarra Coal acquired a more advanced seismic acquisition system from Vibtech in the UK, which enabled high resolution three dimensional surveys to be conducted. Acquisition, …
The Use Of Downhole Presometers Implications For Modern Underground Mines, J. Doyle, G. Poole
The Use Of Downhole Presometers Implications For Modern Underground Mines, J. Doyle, G. Poole
Resource Operators Conference
An understanding of the hydrogeological environment of the strata over and about an operating mine provides some insight into the effectiveness of gas drainage, the identification of potential difficult drainage areas and the behaviour of overlying aquifers during mining. Bore hole piezometers have been routinely installed in BHP Billiton’s exploration holes for many years. The instruments were developed as one of the outcome of NERDCC research grants completed in 1983 and 1986. Piezometers and geophones packaged to survive the difficult environments of the Southern Coalfield remain operational and are routinely read today, twenty years after their installation. The data acquired …
Pike River Coal - Hydraulic Mine Design On New Zealand's West Coast, P. Whittall
Pike River Coal - Hydraulic Mine Design On New Zealand's West Coast, P. Whittall
Resource Operators Conference
Pike River Coal Limited is in the process of developing the Pike River Coal Mine in the Paparoa Ranges of New Zealand’s South Island. The mine will be developed to extract a coking coal deposit of the Brunner Seam, some 46 km north-east of Greymouth, using a combination of continuous miners and hydraulic extraction . The mining area is located within Department of Conservation (DOC) land and is adjacent to the escarpment of the Paparoa Range and the Paparoa National Park. As such, the major restriction to planned extraction is protection of: • The western escarpment; • Vertical and sub-vertical …
Determining The Cotnrols For Strata Gas And Oil Duistribution Within Sandstone Reservoirs Overlying The Bulli Seam, M. Armstrong, P. Hatherly, S. Thomson
Determining The Cotnrols For Strata Gas And Oil Duistribution Within Sandstone Reservoirs Overlying The Bulli Seam, M. Armstrong, P. Hatherly, S. Thomson
Resource Operators Conference
The continuing and effective management of gas within the sandstones overlying the Bulli seam mines of BHP Billiton Illawarra Coal is required to ensure safe and productive mining operations. Recent surface exploration has also detected the presence of oil accumulations in these sandstones which have the potential to impact on future mining operations. Some of these hydrocarbons are located within the longwall relaxation zone of the overlying strata and, as a result, can migrate to the goaf and active workings subsequent to extraction. A number of new exploration techniques, which are in common use by the petroleum industry, have been …

Developing Methods For Placing Sand-Propped Hydraulic Fractures For Gas Drainage In The Bulli Seam, K. Mills, R. Jeffrey, D. Black, T. Meyer, K. Carey, S. Goddard
Resource Operators Conference
BHP Billiton Illawarra Coal is seeking ways to significantly increase gas capture rates from in seam drilling programs in its underground coal mining operations. Hydraulic Fracture Technology (HFT), a joint venture between SCT Operations Pty Ltd and CSIRO Petroleum, is working with Illawarra Coal to develop the capability to enhance gas drainage rates in the Bulli Seam using sand-propped hydraulic fracturing based on HFT’s experience at Dartbrook Mine where gas drainage rates were increased by 5 to 180 times. One of the principal challenges for implementing sand-propped hydraulic fracturing in the Bulli Seam is the high vertical stresses that cause …
