摘要
厚煤层的开采,煤层易自燃、回采率低、工作面推进速度慢、采空区遗煤量多,特别是煤质干燥等极易造成煤炭自燃,对滑放工作面开采带来极大危害,结合-490 m南11层滑放工作面具体情况,采取针对性措施,有效地防止了煤炭自然发火。
Combining with prevention of spontaneous combustion at slip face-490 m south of 11 layer,the author analyzes the great harm caused by spontaneous combustion of coal such as coal spontaneous combustion,low recovery rate,slow face advance,the amount of coal in gob and coal drying,and also introduces practice and application of spontaneous combustion prevention in the thick coal seam.
