基于定性分析与定量研究相结合,探讨了焦作矿区冯营矿的井田构造地质条件、水文地质条件和围岩岩性,以及煤层厚度、埋深和顶底板岩性等因素对瓦斯赋存的影响。通过数理统计的方法,获得了上覆基岩厚度、煤厚与瓦斯含量的回归方程,并对回归方程进行了显著性检验。研究结果表明,水文地质条件对矿井瓦斯总体分布具有控制作用,而地质构造、煤厚、上覆基岩厚度和顶底板岩性是冯营井田瓦斯含量的局部性差异的主控因素。
Based on the combination of qualitative analysis and quantitative research, the geological conditions, hydrogeological conditions and surrounding rock lithology in Fengying Mine in Jiaozuo Mining Area are discussed, and the influence of coal seam thickness, burial depth, top and bottom plate lithology and other factors on gas occurrence . Through the method of mathematical statistics, the regression equation of overlying bedrock thickness, coal thickness and gas content was obtained, and the regression equation was significantly tested. The results show that the hydrogeological conditions have a controlling effect on the overall gas distribution in the mine, and the geological structure, coal thickness, overlying bedrock thickness and top and bottom plate lithology are the main controlling factors for the local differences of gas content in Fengying mine field.
