长期停工综放工作面自然发火风险管控技术

Risk Control Technology for Spontaneous Combustion in Fully Mechanized Caving Face with Long Term Shutdown

针对长期停工综放工作面有效管控自然发火重大风险难题,星村煤矿3306综放工作面通过采取提前处理采空区、降低工作面风量、停工后采空区及两顺槽、支架煤体预处理、降低风流温度、预测预报等综合预防治理措施,实现了对3306综放工作面自然发火重大风险的有效管控。

In view of the long-term shutdown of the fully mechanized caving face to effectively control the major risk of spontaneous combustion,the 3306 fully mechanized top coal caving face in Xingcun Coal Mine has realized the effective management and control of the major risk of spontaneous combustion in the 3306 fully mechanized top coal caving face by taking comprehensive prevention and control measures such as treating the goaf in advance,reducing the air volume of the working face,pre-treatment of the goaf and the two parallel grooves,support coal body,reducing the air flow temperature,prediction and prediction.
