陶二煤矿2号煤瓦斯地质规律研究及突出危险区划分

Study on Gas Geological Regularity and The Outburst Dangerous Area Division of No.2 Seam in Tao'er Mine

为解决陶二煤矿瓦斯突出这一难题,结合该矿的地质特征,对2号煤层瓦斯地质规律进行了研究,分析了煤层瓦斯赋存的影响因素,并采用煤层瓦斯参数结合瓦斯地质分析的方法进行了区域突出危险性预测及划分,研究成果可为瓦斯防治、抢险救灾提供决策依据。

In order to solve gas outburst problem in Tao＇er mine,the paper combined the geological characteristics of Tao＇er mine,the gas geological regularity of No.2 seam in Tao＇ er mine was studied and the influencing factors of the occurrence of coal seam gas were analyzed.Using coal seam gas parameters in combination with the method of gas geology analysis,the regional prediction of outburst dangerous area division was done,which can provide the decision-making basis for the prevention and control of gas,emergency rescue and disaster relief.
