从瓦斯地质理论角度出发,以七星矿井区域地质演化和地质构造特征分析为基础,通过井下采掘过程中揭露的地质构造和采掘工作面的瓦斯涌出数据,定性定量分析了煤层埋藏深度、顶板和底板岩性、地质构造、煤层厚度等因素对8#煤层瓦斯赋存的控制作用,研究结果证明煤层埋藏深度是8#煤层瓦斯赋存的主控因素。
Based on gas geology theory and based on the analysis of geologic evolution and geological tectonic features of Qixing mine area, the geological structure and the gas emission data of mining face during underground mining process are used to qualitatively and quantitatively analyze the burial depth of coal seam, roof and roof Floor lithology, geological structure, coal seam thickness and other factors on the 8 # coal seam gas occurrence control, the results show that the depth of coal seam burial depth is the main controlling factor of 8 # coal seam gas.
