摘要
结合新集二矿瓦斯地质资料,根据测试的煤层瓦斯基础参数,分别绘制了煤层砂岩比与瓦斯涌出量关系图、煤层基岩厚度与瓦斯涌出量关系图和煤层瓦斯含量与煤层埋深的散点图。分析了地质构造、顶板岩性、上覆岩厚度和埋深对瓦斯含量的影响,得出煤层埋藏深度和顶板岩性是影响煤层瓦斯含量的重要因素,井田内断层对煤层瓦斯含量具有控制因素。
Based on the gas geological data of Xinji No. 2 Mine and the measured coal seam gas parameters, the diagrams of the relationship between coal seam sandstone ratio and gas emission amount, and the relationship between coal seam bedrock thickness and gas emission amount, and the scatter diagram between coal seam gas content and the depth of coal seam were plotted. The effects of geological structure, roof lithology, overburden layer thickness and depth on gas content were analyzed respectively. It was concluded that coal seam burial depth and roof lithology were the important factors influencing coal seam gas content. Faults in coal field were the controlling factor for coal seam gas content.
