摘要
本文以双柳煤矿为研究对象,对煤样解吸规律、钻屑解吸指标的测定和现场实测数据,构建了3+4号煤层的突出预测指标体系,采用钻屑瓦斯解吸指标K1作为局部突出危险性预测敏感指标,临界值为0.38m L/(g·min0.5)。该指标可为双柳煤矿瓦斯治理提供指导,对于离柳矿区其他矿井或瓦斯赋存规律类似的煤层防突工作也有一定的参考意义。
In this paper, Shuangliu coal mine was taken as the object of study and the gas occurrence regularity was illustrated. By testing the coal samples of different coal seams in lab, the physical parameters were given. The outburst prediction index system was built. The K1 is taken as part outburst prediction index, the critical value is 0.38mL/（ g · min 0.5）, the drilling cutting quality index as auxiliary index, the critical value is 6.0kg/m. Based on the analysis above, the comprehensive gas control scheme of Shuangliu mine is propesed which can be used in other coal mines with similar gas occurrence condition.
