摘　　要：本文以晋城矿区寺河矿3号煤层为研究区，通过定性和定量分析，对寺河矿的区域构造背景以及瓦斯赋存规律进行了探讨。分析了地质构造、煤层埋深、上覆基岩厚度和顶板岩性等对瓦斯含量的影响，并通过数理统计的方法建立回归方程进行了显著性检验。结果表明，地质构造、埋深和顶板岩性是该矿区瓦斯含量局部性差异的主控因素，而上覆基岩厚度对瓦斯含量也具有控制作用。The regional tectonic background and gas occurrence regularity of No.3 coal seam in Sihe coal mine were discussed based on qualitative analysis and quantitative research in this paper. The analysis on the geological structure, buried depths of coal seam, thickness of overlying rock and roof lithology’s influences on gas content were made, and the regression equation was established by using the method of mathematical statistics to carry on the significance testing.The results show that the geological structure, buried depth and roof lithology are the main controlling factors of gas content’s local variation, and thickness of overlying rock also has a control function for gas content.
