摘要
对石壕煤矿煤与瓦斯突出统计分析,认为煤层埋藏深度、地质构造、地应力和突出煤体结构是影响突出的主要因素。根据瓦斯地质统计法和综合指标法对煤与瓦斯区域突出危险性进行预测,结果表明矿井主采煤层M6-3、M7-2和M8区域为突出危险区,因此在开采中应加强防突措施,为煤矿安全生产提供参数。
Analyzing the statistic data of Shi-hao coal mine,we got that the depth of coalbed,geological structure,crustal stress and the structure of outburst coal are the primary factors of coal and gas outburst. To predict the risky region, the gas geology statistics and comprehensive index method are taken, and show that M6 3, M7 2 and M8 coal area are dangerous. Protection should be strengthened in mining so that accidents can be prevented.
