摘要
针对梅花井煤矿当前长距离单巷、大断面、大埋深、高应力问题,以该矿1104207工作面运输巷为例,介绍了长距离单巷掘进布置方式及支护形式的优化,达到了安全快速掘进的目的。
Aiming at the long-distance single-roadway,large section,great buried depth and high stress ofMeihuajing Coal Mine,the long-distance single roadway driving deployment mode and optimization of thesupport form are outlined in this paper by taking the transport roadway for the mining face 1104207 as anexample for the purpose of driving quickly and safely.
