从区域构造、矿井构造两方面入手,分析了地质构造对矿井瓦斯含量分布规律的控制作用.研究发现,袁店二矿的矿井构造一定程度上继承了区域构造特征,但又具有其特殊性.研究区内褶皱构造不甚发育,断裂构造发育,以东西向和北北东向高角度正断层为主,且呈网格状组合,将井田切割成若干大小不一的断块;区内特殊的地质构造特征控制着瓦斯赋存,从而造就了瓦斯含量分布的不均衡性.

Analysis was carried out on the control effect of the geologic structure on the distribution law of the mine gas content by starting with the regional structure and mine structure. It was found in research that the structure of Yuandian No. 2 mine inherited the features of the regional structures to some extent, but it had its own particularities. The folded structures in the research area did not well developed, the fractured structures developed, most of them were the E-W-trending and NN-E-trending normal faults, they assumed a grid-like combination and cut the mine field into a number of large or small faulted blocks; the special geological structures in the region controlled the gas occurrence, which thus caused the asymmetrical distribution of gas content.
