李村煤矿瓦斯赋存规律及其影响因素分析

通过对李村煤矿地质勘探钻孔资料、试井资料及井田地质条件的分析,应用瓦斯地质理论和线性回归的方法,对李村煤矿3#煤层瓦斯赋存规律及其主控地质因素进行了研究。研究结果表明:煤层埋深、上覆基岩厚度是影响李村煤矿煤层瓦斯赋存的主要控制因素,地质构造在局部构造部位影响煤层瓦斯赋存和富集,煤厚、顶底板岩性、水文地质条件的影响不大。

Analysis on Gas Occurrence Law and Influencing Factors in Licun Coal Mine

Through analyzing the geological exploration and drilling data, well test data and geological conditionsof the mine on Licun coal mine,with the application of the gas geological theory and the method of linear regression, the gas occurrence regularity of Licun coal mine 3#coal seam and the main controlling geological factors are analyzed. The results show that buried depth of coal seam and thickness of overlying bedrock are the main control factors, geological structure partly impacts on the gas occurrence and enrichment of coal seam but some other factors,such as thickness of coal seam,roof and floor lithologic,hydrogeological conditions, have little effect on it.
