摘　　要：对于深部矿井,矿建时期遇到岩体围岩应力较大,在应力作用下,容易发生塑性形变,增加了大型硐室施工及维护的难度。本文以高应力不良岩层下大硐室的施工为例,介绍高应力不良岩层中大硐室的掘进、临时支护、永久支护,及巷道冒顸、变形后的处理方法。此方法在此矿区推广应用,提高了工程质量,保证了施工安全。During the construction of deep mine, the large section chamber is prone to plastic deformation because of the large rock stress, which increases the difficulty of chamber construction and maintenance. Based on the construction of large-section chamber in high-stress and weak rock mass, this paper introduced some treating methods in chamber excavation, temporary support, permanent support, roof collapse and deformation. These methods were applied in mining area, which improved the engineering quality and ensured the safety of construction.
