摘要
针对贵州花秋二矿首采层区域防突措施问题,通过对11606工作面进行瓦斯参数测试,测得煤层瓦斯含量11.69m3/t,煤的坚固性系数为0.51~0.82,平均0.63,最大埋深为374m,煤的破坏类型属II^III类,最大瓦斯放散初速度为19.94,最大煤层瓦斯压力为0.88MPa。根据各项突出参数指标及煤层瓦斯赋存情况,结合《煤矿安全规程》等规定,采取"一面一策"区域防突措施论证,以及区域防突措施的可行性、合理性、经济性分析,选择采用顺层长钻孔预抽煤层瓦斯作为该工作面区域防突措施,为本矿及其他同类突出矿井区域防突措施论证提供了参考和借鉴。
Flowers fall mine of 16 th coal seam outburst coal seam group mining roadway, the regional prevention measures need to be taken in the process, in order to guarantee the normal replacement of mining, using ＂CE＂ demonstrated regional prevention measures through on-site gas parameters measurement, 11606 drivage working face gas content in coal seam 11.69 m3/t, Coefficient of coal a substantial 0.51 to 0.82, an average of 0.63, Max buried deep 374 m, damage type II-III types of coal, as well as prominent report measured maximum gas emission in initial velocity is 19.94, maximum gas pressure is 0.88 MPa is obtained working face with outburst, Through the highlight parameter combines the mine safety regulations（2016）order No. 210, 11606 face outside the scope of provision, based on the feasibility of tunneling in coal face, rationality, economic analysis, bedding boring predrainage methane can be used as a regional prevention measures Provides a reference for other outburst prevention and reference.
