摘　　要：无煤柱开采是提升矿井采掘效率、提高煤炭资源采出率的重要途径。以山西某矿W1319工作面巷道布置为例,提出了留煤柱护巷、无煤柱护巷、工作面过空巷3种巷道布置方式,通过现场调研、理论分析、工程实践论证了无煤柱护巷的可行性,对山西某矿或其他类似条件下矿井进行无煤柱护巷具有良好的指导和借鉴意义。Coal pillarless mining is an important way to increase the recovery rate of coal resources,production and efficiency.The paper is based on the mining design of the W1319 working face of a mine in Shanxi Province.Three kinds of roadway layout were put forward,including retaining coal pillar,protecting roadway without coal pillar and passing through gob roadway.Field investigation,theoretical analysis and engineering practice demonstrate the feasibility of roadway protection without coal pillars.The research results have good guidance and reference significance for the mine in Shanxi Province or other mines with similar conditions.
