A major portion of ground control problems encountered in underground coal mines can be attributed to geological discontinuities in the coal seam and the strata surrounding the seam.
Engineering. This paper presents overview of problems of underground coal mining in India and the need of strata control investigations for improved safety, conservation and economy of the coal mining operations. Instrumentation required for better understanding of strata behaviour around underground opening is presented besides approaches for design of strata control techniques.
The term strata control generally refers to controlling the strata to maintain stability around the mine openings underground where operations are or will be taking place. It does not cover such subjects as subsidence or strata remote from the workings. Strata control is the science (some would suggest art) of utilizing various techniques to prevent or control failure of the strata around mine openings at least for.
The ground control program at the Pittsburgh Research Labo-ratory for than 30 years has focused on numerous safety issues. These include roof bolt effectiveness, bump control, strata deformation, subsidence, retreat mining, and horizontal stress. Integral to each one of these topics and many is.
The NSW Resources Regulator has reported a strata failure incident that occurred at an underground coal mine. According to the report, a roof fall occurred at an intersection in an underground coal mine. The fall was in an outbye area of the mine and extended into the cut-through, blocking the travel road.
Coal Burst. Coal burst is a violent collapse of coal walls and or roofs in underground coal mines. It may happen in the development roadways, at the longwall face or at the chain pillars. As coal mining moves into deeper and geologically complex ground, the risk of coal burst increases for the for Australian coal mining industry.

The NSW Resources Regulator has reported a roof fall incident at an underground coal mine. According to the report, a roof fall, approximately six metres long, measuring the full width of the drive (5.4 metres) and two metres high, occurred in the main gate of an underground coal mine directly behind the continuous miner where the area was supported.

NSW code of practice Strata control in underground coal mines 1 Introduction There were 67 fatalities due to falls of roof and sides at Australian underground coal mines from 1980 to 2008 (see References). These strata-related incidents included • nine fatalities associated with rib falls • 23 fatalities in 18 pillar extraction incidents.
