Research of No. 30 Coal Seams Gas Characteristics in Junde Coal Mine
With the increasing of mining depth, the ground stress increases , and coal seam gas occurrence condition changes , the coal seam gas content and gas emission in the process of mining increases accordingly.The gas occurrence, tectonic evolution characteristics and the control law of the bedrock thickness, coal buried depth, roof , hydrogeology and floor lithol-ogic, magmatic rocks distribution and geological structure of coal seam gas occurrence factors are studied in Junde Mines 30 ＃ coal seam bases on gas geology theory and gas and geology data of Junde Mine.Confirm the major controlling factors of the mine coal seam gas occurrence are coal buried depth, and build the mathematical relationship of bottom elevation and coal seam gas content in gas geology unit separately, which is used in deep coal seam gas prediction, and has great significance in guideing coal seam deep mining and safety production.
