在井下采掘生产过程中,煤层一旦被揭露,则有自燃的可能,可在氧化的过程中自燃,有的煤发火期只有2～3个月。如平顶山高庄矿1/3焦煤就是如此,笔者积十多年与煤自燃处理过程中之经验,总结处理方法有下列六种方法: 一、仓帮仓顶法:在施工巷道通过老巷或上分层停采线的局部地段发现有一氧化碳溢出(煤自燃征兆),可采用 In underground mining production process, the coal seam once exposed, there is the possibility of spontaneous combustion, spontaneous combustion in the oxidation process, and some coal firing period of only 2 to 3 months. Such as Pingdingshan Gaozhuang 1/3 coking coal is true, the author accumulated more than 10 years of experience in the process of spontaneous combustion of coal, summarized in the following six ways: First, the warehouse to help the top law: the roadway through the lanes or Upper stratified cut-off line of local lots found carbon monoxide overflow (coal spontaneous combustion signs), can be used
