1985年9月5日,芙蓉煤矿上平硐63114和63116采煤工作面采空区煤炭自然发火.矿指挥组先后采用调节风压、减少风量、“抢采”的方案进行处理,收到较好效果.一、简要情况芙蓉煤矿上平硐年产30万吨,平硐开拓,采用边界抽出式通风,属高沼气矿井.火区发生在63114与63116两个正在回采的毗邻工作面采空区.63114工作面系单一工作面,U型通风;63116工作面系对拉工作面,工作面上下段系串联渗新方式通风.两个工作面
September 5, 1985, Furong Coal Mine Cave 63114 and 63116 coal mining face spontaneous combustion spontaneous coal mine command group has adopted the regulation of wind pressure, reduce air flow, “grab mining” program for processing, received more Good results First, a brief situation Furong coal mine with an annual output of 300000 tons, open access, the use of border extraction type ventilation, is a high biogas mine.The fire zone occurred in 63114 and 63116 are mining adjacent working face goaf District 6363 working face is a single face, U-type ventilation; 63116 working face pull the working face, the upper and lower face of the work area in series ventilation new way of ventilation. Two working face
