Prediction study on gas emission of the first face in the 11-2 coal seam in Liuzhuang Coal Mine

摘要：

According to the geological exploration about gas information in Liuzhuang Coal Mine, the gas pressure during well construction parameters, and the actual gas emission from tailgate and track trough, the author calculated and got the gas content of the first coal face; combining with coal mining conditions and coal bed methane occurrence conditions, the authors selected the gas emission coefficient from rock k1, the gas emission coefficient from pre-drainage tunnel k2, the gas emission coefficient from residual coal k3 and a series of other forecast parameters, and used subsource prediction method to calculate the gas emission from mechanized mining face and the adjacent layer. Finally, the author got the total gas emission about the first coal mining face in the 11-2 coal seam in Liuzhuang Coal Mine, which provides a theoretical basis for the gas control in Liuzhuang Coal Mine.
