前言煤矿井下自然发火是煤矿生产中的重大灾害之一,它既影响正常生产,损失大量煤炭资源,还威胁工人生命安全。但是,只要措施得力,煤矿的自然发火是完全可以控制和预防的。我国大多数煤矿都是采用黄泥灌浆防灭火。近10年来,有些局矿采用了均压和各种泥浆代用材料灌浆等手段防火。随着煤炭工业的迅速发展,现有的防火技术已不能满足生产需要。特别是西北、西南缺水少土的
Preface Coal spontaneous combustion is one of the major disasters in coal mine production. It affects normal production, loses large amounts of coal resources and threatens workers’ life safety. However, as long as the measures are effective, spontaneous combustion in coal mines can be completely controlled and prevented. Most coal mines in our country use yellow mud grouting to prevent fire. In the past 10 years, some bureau mines have adopted means of pressure equalization and grouting of various mud substitute materials to prevent fire. With the rapid development of the coal industry, the existing fire prevention technology can no longer meet the production needs. Especially the northwest, southwest water shortage of soil
