矿用防灭火注浆装置应用工艺
首先:在常规情况下在掘进巷道中,每隔10m预先埋一个1.5m的一寸花管,如遇特殊的地质情况,如顶板不好,煤比较的破碎,在顶板上形成了比较大的空间,采用埋2.0m—2.4m长的花管,并将常规埋管和特殊地点埋管记录在案。
第二:将白泥(电厂粉煤灰或洗煤厂尾矿、水泥)和水按照一定比例在搅拌机中搅拌均匀,过滤后(过滤器在搅拌桶内),由螺杆注浆泵经?25胶管至插入顶板的花管到达指定的区域。
The death toll in a coal mine explosion in Chinas northwest Xinjiang Uygur Autonomous Region has risen to 76 with another 7 still missing by Tuesday.
The blast ripped through the Shenlong Coal Mine of Fukang County on Monday, when 87 miners were working in the tunnel.
Four workers are known to have survived the tragedy.
Director of the State Administration for Work Safety, Li Yizhong, says there is little chance of survival for the 7 missing miners due to the high density of gas underground.
