【摘要】：根據(jù)平煤十一礦瓦斯地質(zhì)資料,運用瓦斯地質(zhì)理論,研究了平煤十一礦的瓦斯地質(zhì)規(guī)律,得出了礦井瓦斯賦存分布規(guī)律。在分析礦井地質(zhì)構(gòu)造分布特征的基礎(chǔ)上,將井田劃分為兩個瓦斯地質(zhì)單元,即發(fā)育較多封閉型逆斷層的井田東翼為第Ⅰ瓦斯地質(zhì)單元,瓦斯含量高;正斷層為主的井田西翼為第Ⅱ瓦斯地質(zhì)單元,瓦斯含量較Ⅰ單元低。通過定量逐步線性回歸得到兩個地質(zhì)單元中瓦斯含量預(yù)測最優(yōu)方程,得出在東翼第Ⅰ地質(zhì)單元內(nèi)煤層厚度、上覆基巖厚度對瓦斯賦存影響顯著,在西翼第Ⅱ地質(zhì)單元內(nèi)頂板泥巖厚度、上覆基巖厚度對瓦斯賦存影響顯著。
[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，
