摘要
针对下峪口煤矿深部二水平近水平中近距离2~#、3~#煤层群的煤与瓦斯突出灾害特征与规律,按照先区域、后局部的综合防治煤与瓦斯动力灾害防治技术体系在2~#煤层进行了试验,采用了适合该矿条件的突出预测敏感指标体系,并初步确定了突出预测敏感指标临界值。之后使用该指标在下峪口煤矿的扩大验证区域进行试验验证。
Based on the outburst disaster features and law of Xiayukou coal mine, deep in the second level 2^#, 3^# coal seam group, according to the principles of regional policies beforehand and topical measures supplementing, the comprehensive measures were tested in 2^# coal seam, outburst prediction sensitive index system was used, and then outburst prediction sensitive index critical values were preliminary confirmed. After that the critical values were tested by the way of using in other certain places of this coal mine.
