明矾沟煤矿主副斜井突出煤层联合揭煤方法探讨

摘要

通过对明矾沟煤矿主副斜井揭煤区域巷道施工情况、揭穿煤层赋存状况及煤层瓦斯基本参数的分析，提出了主副斜井联合揭煤的技术方法。该联合揭煤方法既可以提高揭煤速度、减少措施工程量、缩短工期，又可节约成本，缓解安全投入少的压力。%In this paper,a combined exposing outburst coal seams in the main and auxiliary inclined shafts in Mingfangou Mine was put forward through the analysis on the roadway construction in the outburst seam exposing area of the main and auxiliary shafts,the occurrence of the outburst seam to be exposed and the basic parameters of coal-seam gas of the mine. This technology of combined exposing outburst seams can not only increase the speed of driving through outburst coal seam,reduce the engineering quantity of outburst-prevention measures and shorten the construction time, but also save the cost and release the pressure of insufficient safety investment.
