【摘要】：针对孟巴矿特厚煤层二分层1210孤岛综放面高地温高湿环境、采空区遗煤多及构造带漏风等复杂条件下开采的特点,分析了煤自燃防治的重点区域,根据生产期间不同时期工作面CO气体的变化情况,综合论证不同防灭火技术的作用效果,采用定期监测、端头封堵后复合胶体隔离、注氮惰化等综合防灭火技术,有效地阻断了煤自燃发展的必要条件,确保了1210孤岛综放面的正常生产和回收。
[Abstract]:In view of the characteristics of mining under complicated conditions, such as high temperature and high humidity environment of 1210 fully mechanized caving face in two layers of thick coal seam in Mengba Mine, more residual coal in goaf and air leakage in structural belt, the key areas for prevention and control of spontaneous combustion of coal are analyzed. According to the change of CO gas in different working face during production period, the effect of different fire prevention and extinguishing technology is comprehensively demonstrated. The comprehensive fire prevention and extinguishing technology is adopted, such as periodic monitoring, compound colloid isolation after end plugging, nitrogen inert injection and so on. It effectively blocks the necessary condition of coal spontaneous combustion and ensures the normal production and recovery of 1210 island fully mechanized caving face.
