丁集煤矿11-2煤层瓦斯地质规律研究

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。

Study on Geological Laws of 11-2 Coal Seam Gas in Dingji Coal Mine

With the gas-geology theory,through analyzing the gas-geology information of Huainan mining area and Dingji Coal Mine,combining with gas content of 11-2 coal seam in geological prospecting and under the shaft,the influencing factors of gas-geological laws about 11-2 coal seam in this coal mine are researched.Through analysing,Dingji Coal Mine can be divided into four tectonic regions,a conclusion is obtained that the major influencing factors are geological structure,revealing of coal seam,the bedrock thickness of coal seam and so on,and it's pointed out that the extrude accidents have a close relationship with crustal stress and geological structure.
