深部巷道由于赋存环境复杂及受到深部地应力作用，加上断面形状尺寸多样，使得巷道的破坏形式多元化。通过系统分析深井软岩巷道受到高应力、动压等因素影响，对比了最大地应力、最大抗压强度以及相对应的支护方式，提出采用应力强度比来评价巷道围岩支护的难易程度。进一步提出了深部巷道主被动全空间协同控制理念，其核心为通过卸压、注浆和锚杆−索等主动支护方式来控制巷道变形，发挥围岩的自承能力，形成主动支护体，恢复其部分承载能力；使用钢管混凝土支架、U型钢等具有较高支护阻力的被动支护方式，构成被动支撑圈，协助或调动巷道围岩发挥承载能力。进而分析了钢管混凝土支架与锚杆−索的协同支护力学机理，形成了主被动全空间协同控制技术及施工工艺并进行了现场应用。研究表明，打设锚杆−索可以降低钢管混凝土支架的弯矩和剪力，同时降低了支架轴力，保护了钢管和抗拉性能较差的核心混凝土，保证了钢管混凝土支架能够提供较高的支护阻力；主被动全空间协同控制技术在晋城胡底煤矿、阳泉新元煤矿等深部动压巷道与软岩巷道中进行了成功应用，进一步发展了深部巷道等强支护理论与技术。

Due to the complex environment and ground stress at depth, and the various cross-sectional shapes and sizes, the damage types of deep roadways are diversified. The maximum ground stress, maximum compressive strength, and the corresponding support methods are compared by systematically analyzing the influence of high stress and dynamic pressure on the deep weak surrounding rock of roadways. And the stress intensity ratio is proposed to evaluate the support difficulty of surrounding rock of roadways. Then, the concept of active-passive full space collaborative control is proposed, and the core of the concept is to control the deformation of the roadway through active support methods such as destressing, grouting and bolt-cable to bring the self-supporting capacity of the surrounding rock of roadway into play, forming an active support body, and restoring its partial bearing capacity. Using passive support methods such as concrete-filled steel tube sets and U-shaped steel sets with high support resistance to form a passive support ring to assist or mobilize the bearing capacity of the rock surrounding roadways. Additionally, the mechanical mechanism of the collaborative support for concrete-filled steel tube sets and bolt-cable were analyzed, and the active-passive full space collaborative control technology and construction technique were developed and applied in the field. The study shows that the bolt-cable can reduce the bending moment and shear force of the concrete-filled steel tube sets, while reducing the axial force of the support and protecting the steel tube and the core concrete with poor tensile properties. The active-passive full space cooperative control technology has been successfully applied in deep roadway subjected to dynamic pressure and weak rock roadway in Jincheng Hudi Coal Mine and Yangquan Xinyuan Coal Mine, which has further developed the theory and technology of equal-strength support in deep roadway.
