Study on Gas Geological Laws of Aai Mine Area

Based on the geological and production data of Aai Mine Area, applying theory of gas occurrence control structure step by step, the mine area geological tectonic evolution and distribution characteristics were analyzed, and the influence factors of gas occurrence were studied, such as the geologic structure, lithological characters of roof and floor, coal seam buried depth and thickness of coal seam and tectonic coal. In combination with the determination of coal seam gas parameters in the process of geological exploration and production, the gas-geology laws of Aai Mine Area were obtained. Research shows that tectonic coal and buried depth of coal seam are the main controlling factors affecting coal seam gas occurrence.
