摘要
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。
On the analytical structure development characteristics, mainly discussedthe control of fault structure and fold structure of gas occurrence on the basis of the mining production data and geological prospecting results of Linxi mine. The research findings show： Linxi mine are composed of fold structure, where large and high angle noemal faults are developed by fold and F1 fault, and they are mostly open faults. The openness of the fault provides a good channel for the escape of gas; and the permeability of faults to coal seam of dish rock would be favorable for gas relesed.
