摘要 沿空留巷技术推广过程中部分留巷变形严重,无法继续为下一个工作面服务。通过对留巷工作面侧巷帮采用掘进机扩帮、全断面拉底维修,满足了巷道回采需要,缓解了矿井采掘接续紧张问题,为切顶沿空留巷巷道快速维修提供了借鉴。 During the popularization of gob-side entry retaining technology,some of the gob-side retaining roadways are seriously deformed and cannot continue to serve the next working face.By using roadheader to expand the sides of roadway and carrying out bottom-drawing maintenance on the full section,it can meet the needs of roadway stoping and relieve the tension of mining continuity,which provides a reference for the rapid maintenance of retained roadway along the goaf with roof cutting.
