Study on Gas Geology Characteristics and Gas Control Countermeasures in Pingbao Company

According to the problem of high gas content and pressure in coal seam of Pingbao company, the laws of gas occurrence in Pingbao company were anal yzed, and the causes of coal and gas outburst were discussed from the point of outburst- prone tectonophisical environment. The results showed that the coal seam de pth, roof and floor lithology, geological structure and hydrogeological had mainly effect on the coal seam gas occurrence, and the synthetic action of multi factors of the outburst- prone tectonophisical environment controled coal and gas outburst. The countermeasures for gas were proposed in Pingbao company, including strengthening gas geology study, protective seam mining, efficient coal seam pre- drainage and establishing the reliable early- warning system of coal and gas outburst, which could p rovide technical support for mining safety.
