运用瓦斯地质学理论,通过对淮南矿区和丁集煤矿瓦斯地质资料的分析,结合丁集煤矿11-2煤层地堪瓦斯含量和井下实测瓦斯含量,研究了影响该矿11-2煤层瓦斯地质规律的各种因素。通过分析,可将丁集煤矿划分为4个构造区,并得出地质构造、煤层露头和煤层底板上覆基岩厚度等是影响丁集煤矿11-2煤层瓦斯变化的主要因素,同时指出该矿发生的突出事故与地应力和地质构造有密切关系。
Based on the gas geology theory and the analysis of gas geological data in Huainan Mining Area and Dingji Coal Mine and the gas content in Well 11-2 of Dingji Coal Mine and the measured gas content in underground mine, Various factors. Through the analysis, the Dingji coal mine can be divided into four tectonic zones, and the geological structure, the outcrop of coal seam and the overburden bedrock thickness of coal seam floor are the main factors that affect the gas change in 11-2 coal seam of Dingji coal mine. Outburst accidents occurred in the mine are closely related to geostress and geological structure.
