滴道盛和煤矿立井18^#煤层瓦斯地质规律分析

摘要: 在现场收集大量瓦斯与地质资料的基础上,结合大量的实测数据,采用瓦斯与地质理论相结合的方法,定性定量分析了滴道盛和煤矿立井18^#煤层的瓦斯地质规律。分析了地质构造、煤层顶底板岩性、岩浆岩侵入、煤层底板标高对瓦斯赋存的影响,并对矿井瓦斯涌出量进行了预测。

Abstract: On the basis of on-site collecting a lot of gas and geological data,with a large number of measured data,Using a method of combining gas and geological theory,gas geology laws in vertical shaft of Didaoshenhe coal mine No.18 coal seam are analyzed qualitatively and quantitatively.The influencing of geological structure,roof and floor lithologic,magmatic intrusion and coal seam floor elevation on gas occurrence is analyzed,and the gas emmission of coal mine is predicted.
