平宝公司瓦斯地质特征及瓦斯防治措施研究

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

针对平宝公司煤层瓦斯含量高、瓦斯压力大的问题,分析了平宝公司煤层瓦斯赋存规律,并从构造物理环境角度探讨了煤与瓦斯突出原因。结果表明:煤层埋深、顶底板岩性、地质构造及水文地质条件是影响煤层瓦斯赋存的主要地质因素,煤与瓦斯突出构造物理环境多因素的综合作用控制煤与瓦斯突出。提出了针对平宝公司的瓦斯综合防治措施:加强瓦斯地质研究,保护层开采,煤层瓦斯高效抽采及建立可靠的煤与瓦斯突出预警系统,为矿井安全生产提供技术保障。

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 analyzed,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 depth,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 provide technical support for mining safety.
