摘　　要：近距离采空区对于下层煤采掘工作面稳定性具有显著影响,严重时会导致下层煤采掘工作面难以正常支护和生产。为保障三交河煤矿2^(-2#)近距离采空区下掘进工作面的安全高效生产,借助数值模拟、理论分析、现场调研等方法,开展工作面顺槽合理位置及支护方案的研究。2^(-2#)煤层回采工作面顺槽设计为同向内错布置方式,并采用锚网梁、锚索、架棚组合支护技术;实践表明,该顺槽巷道掘进阶段未出现明显的矿压现象,其工作面布置及支护方式可推广应用。Aiming at the influence of close-distance goaf on the stability of mining face in underlying coal bed in 2^(-2#) mining face of Sanjiaohe Colliery,the paper probes into the rational position of crossheading and support scheme by means of numerical simulation,theoretical analysis and on-site survey,and proposes the layout pattern of copropagating inner alternate and the combined support with anchor-mesh-beam,cable and scaffold,whose application results show there is no obvious strata behavior again during the roadway driving with the value of popularization and application.
