Study on gas-geology regalarity of Aiweiergou mining area
Abstract：According to the geological exploration and the gas geological data which are exposed in the mine production, the paper researches the gas-geology regularity of the Aiweiergou mining. This research also analyzed the effects of tectonic evolution, burial depth of coal seams, tectonic evolution, metamorphic grade of coal to the gas bearing. The research revealed that the main factor is the burial depth of coal seams, and the other factors are tectonic evolution, metamorphic grade of coal and part of the region is affected obviously by the tectonic. As the result, along the trend of coal seam gas content in the western mining is the highest, the eastern mining＇s secondary, and the central mining＇s the least. Along with the coal seam orientation direction, the linear relationship obviously can be found between the gas content and seam depth which the gas content increased with the increase of the coal burial depth.
