Study On The Prevention And Control And Administrative Method Of The Pressure Bump In Depth Of Xinwen Mining Area

Pressure bump is one of the most serious natural calamities in coal mines in the world, especially the destroy intensity for its striking is more serious over certain critical depth. Because the mining depth in Xinwen area is extremely deep, the pressure bump has been imperiling seriously safe mining in coal mines. For this reason, some effective administrative measures and scientific methods must be taken to resolve safe mining problems in the depth of mining areas.In this paper, the mechanism that bring out the rock burst was analyzed, and some factors that brings out the rock burst was found out by analyzing some cases of Suncun coal mine. Simultaneously, the impact extent of predicting pressure bump in depth and controlling scheme model was set up by using numerical simulation software FLAC^3D INTERFACE unit. For the second and forth coal seams and their surrounding rocks, the model calculated and analyzed the distribution pattern of stress in different mining and moving condition and dangerous extent that pressure bump takes places. According to an analyzing conclusion, that some control schemes and synthetic prevention and control measures must be taken was put forward. On the basis of experience of preventing and controlling pressure bump, linking administrative characteristic in Xinwen mining area, administrative system of safe mining technology under the pressure bump in depth was set up, and safe-mining the deep coal seam in Xinwen mining area was guaranteed.Through studying prevention and control pressure bump andcarrying out the administrative system, the prevention and control pressure bump in depth of Xinwen area were realized , and the decision system of scientific and effective prediction and prevention and control was formed, and the fine social benefit and marked economic benefit.
