【摘要】 本文以拜家河煤矿南下山冒顶区煤炭发生自燃火灾为研究对象,在经过初期封闭井筒、构造密闭等方法进行隔绝法灭火,启封火区后煤炭发生复燃并发生爆炸事故的复杂环境下,该煤矿采用地面钻孔对井下火灾进行灌注清水灭火。该煤矿进行了地面钻孔位置选择设计,计算了灌注清水体积,进行气体、温度和水位监测,为同类型煤矿地面钻孔清水灭火提供工程实践借鉴。更多还原

【Abstract】 The roof caving zone of Nanxiashan in Baijiahe coal mine which has happened spontaneous combustion fire was studied in the thesis. During initial period, we took Isolation method of extinguishing like Closed wellbore and structural trap. After fire zone reopening, coal happened again with explosion, and then we took surface drilling and poured water into the well to put out the fire. We also designed how to choose the ground drilling location; Calculated the volume filling water and monitored gas, temperature and level. These Provide engineering reference for the same type coal mine which using surface drilling and Water fire extinguishing technology.更多还原
