摘要
针对特厚自燃煤层采用综放开采后,采空区遗留大量浮煤,浮煤集聚易引起自燃的问题,结合小峪矿8206工作面实际情况,提出采用黄泥灌浆、采空区注氮和喷洒阻化剂相结合的综合防治技术。并在工作面初采、停采撤架和停产期间制定相应的专项防治措施,采空区自然发火现象得到有效控制,取得了良好的应用效果。
In view of the application of fully mechanized top coal caving in super thick spontaneous combustion coal seam, there is a large number of floating coal left in goaf. Combined with the actual situation of the 8206 working face of Xiaoyu Mine, the integrated control technology combining yellow mud grouting, goaf injection nitrogen and spraying inhibitor is put forward. And the corresponding preventive measures shall be worked out during the initial mining, stopping, withdrawal and production of the working face. The phenomenon of spontaneous combustion in goaf has been effectively controlled, and good application results have been achieved.
