摘　　要：通过对魏家地煤矿地质构造、煤层顶底板岩性、煤的变质程度及煤岩组分、煤层厚度及结构、煤层埋藏深度等分析研究,总结了瓦斯赋存的规律,同时也对煤与瓦斯突出危险性进行了分析研究,这一成果可以对今后矿井瓦斯防治乃至煤层气的抽采利用提供技术依据。It researched on mine geological structure, roof and floor lithology of coal seam, coal metamorphism and coal maceral, coal seam thickness and structure of the coal seam and buried depth of Weijiadi Coal Mine,it summed up of gas occurrence law,but it also researched on coal and gas outburst hazard risk, this outcome can provide the technical basis for future mine gas prevention even coal- bed methane drainage and utilization.
