摘要：阐述了煤矿巷道围岩的破坏形式，将围岩破坏分为拉裂破坏和剪切破坏 2 种类型，将地层压力分为变形压力、
松动压力和膨胀压力，分别详述了不同压力下巷道围岩失稳机理，结合巷道围岩破坏类型及失稳机理，提出了煤矿巷道
锚杆（索）分次支护技术。

Abstract: This paper expounded the failure forms of surrounding rock of coal mine roadways, which divided the surrounding rock
failure into tension fracture failure and shear failure, divided the formation pressure into deformation pressure, loosening pressure
and expansion pressure, and detailed the instability mechanism of surrounding rock of roadways under different pressures, puts
forward the bolt (cable) graded support technology of coal mine roadway combined with the failure types and instability mechanism
of surrounding rock of roadways.
