马家沟煤矿石门揭煤发生突出的危险性分析

Analysis of Occur of Outburst in Majiagou Coal Mine Rock cross-cut coal

应用初始释放瓦斯膨胀能指标法和综合指标法,对石门揭煤的突出进行了危险性分析。经计算证明,与常用的预测方法相比,该方法将影响突出的多个因素综合来考虑,跳出了常规预测方法只依靠单一指标进行预测的圈子,提高了预测的准确性。研究结果表明,马家沟矿10水平在石门揭煤条件下具有发生煤与瓦斯突出的危险性。

With the application of the methods of the energy the initial releasing gas and the aggregate,the paper will mainly focus on the analysis of the outburst of the rock cross-cut coal uncovering.According to he calculation ,it proves that the result broke the predicative experiment result in which the methods is based on just single inder.However,the new method takes the most affective outburst factors into consideration. The research result indicates that the 10th of Majiagou Coal Mine Rock cross-cut coal will have occur of coal and gas outburst.
