通过对煤田地质勘探、钻孔揭煤资料的分析,应用煤层瓦斯赋存理论和回归分析方法,分析了平煤六矿戊8煤层瓦斯赋存规律,探讨了煤层赋存及瓦斯含量与煤层埋藏深度、底板标高、煤层厚度、顶底板岩性、地质构造等因素的关系。分析结果显示,煤层埋深是影响煤层瓦斯含量的主要因素,断层及煤层顶底板岩性对戊8煤层瓦斯赋存起主控作用。
Through the analysis of the geological exploration of coalfield and the data of borehole unclarified coal seam, the gas occurrence law of the E8 coal seam in Pingdingshan Sixth Coal Mine is analyzed by using the gas deposit theory of coal seam and the regression analysis method. The occurrence and gas content of coal seam and the burial of coal seam Depth, floor elevation, seam thickness, roof and floor lithology, geological structure and other factors. The results show that the depth of the coal seam is the main factor that affects the gas content of the coal seam. The faults and the top and bottom lithology of the coal seam play a dominant role in the gas occurrence in the E8 coal seam.
