谢桥矿8煤层瓦斯赋存规律及主控因素分析

Analysis on Gas Deposit Law and Main Control Factors of No.8 Seam in Xieqiao Mine

文章运用瓦斯地质理论和方法,依据井田内大断层发育规律,将谢桥8煤层划分成西单元和东单元,然后根据谢桥8煤层地勘瓦斯含量和实测瓦斯含量数据,分析了两个地质单元的瓦斯分布特征,并找出了影响谢桥8煤层瓦斯赋存的主要因素,从而为谢桥矿的煤与瓦斯突出危险性预测提供了依据。

With the gas geological theory and method and base on the development law of the major faults in the minefield,the No.8 seam in Xieqiao Mine was divided into the West Unit and East Unit.Then base on the gas content of the No.8 seam exploration and the measured gas content data in Xieqiao Mine,the gas distribution features of the two units were analyzed and the main factors affected to the gas deposit law of the No.8 seam in Xieqiao Mine,which could provide the references to the prediction of the coal and gas outburst dangers in Xieqiao Mine.
