摘要
基于瓦斯地质学理论,根据平岗煤矿瓦斯地质资料,采用瓦斯赋存构造逐级控制理论方法,研究了断层、褶皱、顶底板岩性、上覆基岩厚度、构造煤分布等因素对平岗煤矿瓦斯赋存的影响。建立了上覆基岩厚度与瓦斯含量的数学模型,并进行了回归分析。研究结果表明:上覆基岩厚度是影响平岗煤矿瓦斯赋存的主控因素,瓦斯含量随上覆基岩厚度的增大而增大。依据煤层瓦斯含量与上覆基岩厚度的线性回归关系对矿井深部的瓦斯含量进行了预测。
Based on the theory of gas geology,and according to the data of gas geology in Pinggang Coal Mine,the paper studies how fault,fold,roof and floor lithology,the thickness of the overlying bedrock and tectonic coal distribution influence the gas occurrence of Pinggang Coal Mine.A mathematical model of the thickness of the overlying bedrock and the gas content has been established and the regression analysis has been done.Results show that：the thickness of the overlying bedrock is the main controlling factor which influences the gas occurrence of Pinggang Coal Mine.The gas content increases with the thickness of the overlying bedrock.The gas content of the deep mine was also predicted based on the linear regression relationship of gas content and the thickness of the overlying bedrock.
