摘要
本文通过煤层开采条件复杂、自燃发火期仅7—15天的彭家冲井自燃原因的分析和防火实践,指出采用综合治理,把各种防火手段有机地结合起来,在技术上是可行的,防火效果是显著的.
In this paper the writer discuss the seams being worked in Penjachong Mine.The seams are under complex geological conditions and are highly liable to spontaneous com- bustion with the incubation period of only 7 to 15 days.Based on the analysis of the causes of spontaneous combustion in seams in question and the fire prevention practice therein,it is pointed out that the comprehensive measures for fire prevention,namely,the organic combination of various fire prevention approaches,are technically feasible and obviously ef- fective for fire prevention.
