Coal Operators’ Conference The AusIMM Illawarra Branch 10 6 – 7 July GROUND CONTROL IN COAL MINES IN GREAT BRITAIN James Arthur 1 ABSTRACT: In deep coal mining support of the underground roadway is fundamental and without knowledge of the mechanics of ground control a mine is unlikely to be operating safely and efficiently. Mining, Underground the aggregate of operations to open and develop a deposit and remove ores, nonmetallic minerals, and coals. A different technology is applied in underground leaching, underground solution, and other underground mining procedures that use boreholes. The opening operation is accomplished with vertical and inclined shafts or drifts. Ground falls have historically been responsible for nearly 50% of all fatalities in underground bituminous coal mines (Mark, Pappas & Barczak, ). Roof bolting in coal mines began on a modest scale in the early s. Since then, the design of bolts, grout systems, accessories and installation techniques has improved by: 2.

The U.S. Bureau of Mines has compiled information from several sources on the geological features that contribute to ground control problems in underground coal mines. The compilation includes sedimentary features such as paleochannels, crevasse splays, clastic dikes, mold and cast structures, concretions, lithologic factors, and structural features, such as folds, fractures, joints, cleat, and faults.

The. influence of discontinuities on. Three depositional features dominate where unstable roof occurs in western underground coal mines: paleochannel deposits, crevasse splay deposits, and flood basin deposits.
Three structural features identified as hazardous, but not so widespread or common as the depositional hazards, are faulting, joint- ing, and igneous intrusions. archeological mapping. The following are rcccnt applications in both coal and hard-rock mines.

Currently, underground coal production in the U.S. is split almost between large longwall mines and. In general, as underground mines become older and deeper, they are more prone to incidents of ground. instability. Currently, several Ontario underground mines operate at depths approach feet.
Ground control generally involves a variety of engineering and operational measures to control, monitor. and prevent falls of ground and. geological features such as joints may pose serious strata control problems.
Unfavourable intersection of these discontinuities namely, faults, joints and mining induced stress fractures tend to divide the immediate hangingwall into unstable keyblocks which, if not supported, may result in extensive falls of ground.
Effective. He has performed research and/or problem investigation in more than U.S. coal mines and 16 major coal producing countries.
He founded the annual International Conference on Ground Control in Mining (ICGCM) in Through his effort, Ground Control is now a standard terminology in mining operations.5/5(1).
As coal mining methods and activities have changed over the years, the effects on the geologic conditions have also changed. Underground operations have grown from small family mines to obtain house coal for heating to large, commercial operations, and the respective mining methods have changed from narrow, hand-cut tunnels, through room-and-pillar mines with pillars left in the mines.
number of problems of the domestic coal industry that do not allow to fully realize competitive advantages, includes an increase in the proportion of underground coal mining performed in adverse geological conditions (Shmatko, ).
Over the past ten years, the average depth of the bed mining in mines increased by 12%, reaching meters in Once under- ground, the geologic features of particular interest to the geologist himself are (1) orientation of coal cleats, (2) occurrence of clay veins, (3) occur- rence of faults, (4) sandstone-or claystone-filled channels, (5) abnormally high concentrations of gas and water, and (6) roof by: 6.

It covers parts of the “Thorez” and “Victoria” coal mines (Fig. The area has been selected for several reasons, i.e.: available, for analysis, results of past geodetic measurements, ground deformation forecasts made for the period that indicated the.
Geologic features, including sandstone channels, faults, and seam dips, have been associated with the events. Certain mining layouts and practices also increase the burst risk, as does a past history of bursts. Each of these factors is discussed in more detail below.
Cited by: These problems cause injuries, multifatalities, and major asset losses until precautions are taken to control these problems. Coal mine failures are affected by various factors such as geological.
This study constructs a hazard map for ground subsidence around abandoned underground coal mines (AUCMs) at Samcheok City in Korea using a probability (frequency ratio) model, a statistical (logistic regression) model, and a Geographic Information System (GIS). To evaluate the factors related to ground subsidence, an image database was constructed from a topographical map, geological Cited by: The influence of discontinuities on coal measures is manifested in the form of roof and side falls, caving of the roof and sometimes in subsidence of the ground surface.
This review paper is confined to roof falls due to major geological discontinuities (such as faults, joints, cleats and bedding planes) and to possible ways and means to prevent these falls.

25th International Conference on Ground Control in Mining ABSTRACT Bowie Resources maintains one of the most pro-active ground control programs in the U.S. mining industry today. Its guiding philosophy is that everyone in the organization, from the miners at the face all the way through the top management, are involved in ground control.

Geotechnical Considerations in Underground Mining/Department of Industry and Resources Guideline Document No.: ZMEQT INTRODUCTION The potentially hazardous nature of underground mining requires the application of sound geotechnical engineering practice to determine the ground conditions, the ground support and reinforcement requirements, as File Size: KB.
Coal is mined by both pdf or ‘opencut’ (or opencast) and underground or ‘deep’ mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia’s coal is produced from opencut mines.other coal seams.
To describe the problems, then to identify the causes of these disturbances in Illinois coal seams required exten- sive mapping of both surface and underground mines. Field investigation for this project covered every active mine in Illinois.
