【摘要】：為解決大北礦102工作面裂隙發(fā)育煤層自然發(fā)火的難題,分析了該工作面自然發(fā)火的原因,并提出了"一通,二注,三監(jiān)測"綜合防滅火技術(shù);采用該技術(shù)后,煤壁與巷內(nèi)空氣溫差0.3℃~1.4℃,采空區(qū)CO濃度3×10~(-6)~16×10~(-6),遠(yuǎn)遠(yuǎn)低于CO預(yù)警臨界濃度1×10~(-4),有效解決了102工作面煤體自然發(fā)火的難題。
[Abstract]:In order to solve the problem of spontaneous combustion of coal seam in No. 102 face of Dabei Coal Mine, this paper analyzes the reason of spontaneous combustion in this working face, and puts forward the comprehensive fire prevention and fire extinguishing technology of "one pass, two injection and three monitoring". With this technology, the air temperature difference between coal wall and roadway is 0.3 鈩，
