影响裴沟矿煤层瓦斯赋存规律的地质因素分析

Analysis on Geologic Factors Affecting Peigou Mine Coal Sesm Methane Occurrence Regularity

以地质勘探期间实测瓦斯含量、钻孔揭煤资料为基础,使用瓦斯地质因素分析和线性回归的分析方法,分析控制煤层瓦斯含量的地质因素,详细分析了裴沟矿煤层瓦斯赋存与地质构造、煤层厚度、煤层围岩、煤体结构、煤层埋藏深度等地质因素之间的关系,得出了断层、煤层顶板40 m范围内的含砂率、煤层的埋藏深度是影响裴沟矿瓦斯赋存的主要地质因素,从而为采掘部署和瓦斯防治工作提供理论依据。

Though analyzing the methane geologic data in the Peigou Mine, based on road - tested gas content, drill coal uncovering information, this paper analysis of geological factors controlling the content of coal bed gas using the methos of coal bed gas geological factors analysis and linear regression, and discussed the geologic factors for coal seam methane occurrence and distributinon regularity, such as geological srtucture, coal seam thickness , coal bed surrounding rock, coal structure, burial depth of coal -bed and so on. It also analyzed the relationship between all factors and Peigou Mine coal bed gas occurrence regularity, that the main controlling factors of affecting seam methane occourenee are geoglogical structure, 40 m sand content rate and burial depth of coal - bed ,This provides theoretical basis for the work of layout of mining and methane prevention.
