摘　　要：鲍店煤矿5304采煤工作面采用特厚煤层分层的开采方式,采空区漏风规律复杂,给矿井的安全生产带来很大的危险。论文根据矿井的实际情况,分析了5304采煤工作面在煤自燃防治方面存在的难点;根据特厚煤层分层开采煤自燃的层位定律,对煤自燃易发地点"两道两线"进行了分析,确定了5304采煤工作面防火的重点部位;结合该煤层自燃的特点和规律,从上下分层及上分层沿空侧三个部分研究了不同时期的煤自燃防治技术,有效保障了矿井的安全生产。The 5304 mining face of Baodian coal mine used the mining method ofslice mining of special thick coal seam, the the air leakage law in the gob is complex,which brings great dangerto mine safety production. According to the actual situation of the mine,the paper analyzed the existing difficulties of 5304 coal mining facein the aspect of the prevention and control of coal spontaneous combustion. According to the layers law of coal spontaneous combustion for slice mining of special thick coal seam, the locations ＂two tunnel two lines＂ of prone to coal spontaneous combustion were analyzed. The key positions of fire prevention 5304 mining face were determined.Combining with the character- istics and laws of spontaneous combustion of this coal seam,the techniques of prevention and control of coal spontaneous combustion were studied from the three parts of upper layer and lower layer, and upper layer along the empty side different periods, it effectively protected the mine safety production.
