摘　　要：为了提高煤炭资源的回采率和缓解采掘接替紧张,采用了无煤柱开采技术。在无煤柱开采技术中,切顶卸压沿空成巷无煤柱开采是目前广泛应用的主流技术。分析了切顶卸压沿空成巷无煤柱开采技术的关键内容,主要是巷道恒阻锚索支护和定向预裂切顶,并分析了该技术在山西A矿的应用。切顶卸压沿空成巷无煤柱开采技术的应用,不仅提高了煤炭资源回收率,还降低了成本,缓解了采掘接替紧张。In order to improve the recovery rate of coal resources and relieve the tension of mining and tunnelling replacement,the non-pillar mining technology is adopted.In non-pillar mining technology,non-pillar mining technology of top-cutting pressure relief roadway formed along gob widely used at present.This paper analyzedthe key content of non-pillar mining technology of top-cutting pressure relief roadway formed along gob,mainly including roadway constant resistance anchor cable support and directional pre-split roof cutting,and analyzed the application of this technology in A Mine of Shanxi.The application of non-pillar mining technology of top-cutting pressure relief roadway formed along gob can not only improve the recovery rate of coal resources,but also reduce the cost and relieves the tension of mining and tunnelling.
