Influence of Geological Structure on Gas Occurrence Law in No.5 Coal Mine in Hebi Coal Chemical Industry Group

Dong Da

Abstract

Gas has become a prominent factor of hampering coal mine production.The gas occurrence state in coal seam is a technical basis of researching the gas emission law and prevening gas disasters.The gas emission factors in coal mines were analyzed by research on gas geological law in No.5 Coal Mine.At the same time,it is pointed out that there is coal and gas outburst danger in the high gas development areas with structure coal in the deep mine.There is guiding signifincance for gas disaster prevention in the deep mine.
