摘　　要：掌握煤层瓦斯的赋存特征,是有效防治瓦斯灾害和煤层气资源合理开发利用的前提和科学依据。为了研究漳村煤矿3#煤层的瓦斯赋存特征,运用瓦斯赋存构造逐级控制理论,并结合实测的煤层瓦斯含量,分析了地质构造对瓦斯赋存的控制作用,以及顶底板、埋深等地质因素对瓦斯赋存的影响,认为上覆基岩厚度是影响漳村煤矿3#煤层瓦斯赋存的主控因素,煤层瓦斯含量随上覆基岩厚度增加而明显增大,以此绘制了瓦斯含量趋势等值线,更加直观的反映瓦斯赋存特征。Distribution characteristics of coal seam gas control is an effective control of gas disaster and the rational exploitation of coal bed methane resources and the scientific basis for the premise.In order to research the zhangcun coal 3 # of coalbed gas occurrence characteristics, using a gas occurrence tectonic cascade control theory, combined with the measured data, the authors studied geological structures of gas occurrence and control action of coal seam roof lithology, buried depth factors such as the impact of gas content~ The authors think that the thickness of the overlying rock zhangcun coal seam gas occurrence 3 # is the controlling factor, seam gas content increases with the thickness of overlying bedrock increase significantly, based on than drawing the contours of the gas content trends in order to reflect the characteristics of gas occurrence more intuitivly .
