摘　　要：基于杉木树煤矿开采强度和深度的日益增加,动压影响的加剧,传统支护体系下巷道底鼓片帮严重,该矿以N26采区轨道下山工程实践为背景,通过应用理论分析和现场观测的手段,研究了复杂矿压下的巷道软岩支护的技术,并在现场试验了采用“高强预应力锚杆﹢W型钢带﹢锚索”的支护方案,通过近150天的观测,最大变形量34mm,主要是较微底鼓造的。实现了复杂矿压下巷道软岩巷道的可靠维护,为今后深部水平的巷道支护提供科学的理论依据。In this paper,based on the theory of high-strength support and the application of high-strength support system in the field of soft rock mining in Shanmushu Coal Mine,the application of high-strength support technology in the field of soft rock support under the inf luence of high-strength support system in the field of soft rock support and support in the field was increased According to the observation of nearly 150 days,the maximum deformation is 34mm,which is mainly caused by the slight floor heave.It realizes the reliable maintenance of soft rock roadway under complex mine pressure,and provides scientific theoretical basis for deep level roadway support in the future.
