【摘要】：根据平煤十一矿瓦斯地质资料,运用瓦斯地质理论,研究了平煤十一矿的瓦斯地质规律,得出了矿井瓦斯赋存分布规律。在分析矿井地质构造分布特征的基础上,将井田划分为两个瓦斯地质单元,即发育较多封闭型逆断层的井田东翼为第Ⅰ瓦斯地质单元,瓦斯含量高;正断层为主的井田西翼为第Ⅱ瓦斯地质单元,瓦斯含量较Ⅰ单元低。通过定量逐步线性回归得到两个地质单元中瓦斯含量预测最优方程,得出在东翼第Ⅰ地质单元内煤层厚度、上覆基岩厚度对瓦斯赋存影响显著,在西翼第Ⅱ地质单元内顶板泥岩厚度、上覆基岩厚度对瓦斯赋存影响显著。
[Abstract]:Based on the gas geological data of Pingmei No. 11 Mine and the theory of gas geology, the gas geology law of Pingcoal No. 11 Mine is studied, and the distribution law of gas occurrence in the mine is obtained. On the basis of analyzing the distribution characteristics of mine geological structure, the mine field is divided into two gas geological units, that is, the east wing of mine field with more closed reverse faults is the first gas geological unit with high gas content; The west wing of normal fault is the second gas geological unit, and the gas content is lower than that of unit 鈪，
