基于林西矿矿井生产资料和地质勘探结果,以解析构造发育特征为基础,深入探讨了井田断层、褶皱和岩浆岩对煤层瓦斯赋存的控制作用。研究结果表明:林西矿以褶皱构造为主,受褶皱和F1断层影响发育较多小型高角度正断层,且多为开放性断层。断层的开放性为瓦斯的逸散提供良好的通道;而断层与煤层接触对盘岩性的透气性越好,越有利于瓦斯逸散。
Based on the production data of Linxi Mine and the geological exploration results, based on the analysis of tectonic development characteristics, the control action of minefield faults, folds and magmatic rocks on the gas occurrence of coal seams is discussed in depth. The results show that the Linxi mines are mainly fold structures, and are affected by folds and F1 faults with more small high-angle normal faults and mostly open faults. The openness of the fault provides a good channel for the dissipation of methane. The better the permeability of the fault to the coal seam is, the more it is conducive to the dissipation of gas.
