余家寮井田瓦斯赋存规律

Research on Gas Bearing Law in Yujialiao Coalfield

运用瓦斯地质理论,结合地质勘探和矿井生产揭露的瓦斯地质资料,研究了梅田矿区余家寮井田的瓦斯赋存规律。综合分析了地质构造、顶底板岩性、煤层埋深、岩浆岩等对煤层瓦斯赋存的影响,预测了井田瓦斯含量,根据研究的瓦斯分布规律和瓦斯涌出量规律,可以更有针对性地制定瓦斯治理及施工措施,对煤矿的安全高效生产具有重要意义。

The theory of gas geology,combining the geological data of geological exploration and reveal of mine production,the gas bearing law in Yujialiao coalfield was discussed.The affect of methane occurrence in geological structure,top and bottom plate＇s litho logy,burial depth of coal seam and magmatic rock were analyzed,the content gas in the field was predicted,according to the law of gas distribution and occurrence,the measure of gas control more pertinency can be set out and it would be of great impotence in safety and high-effect production.
