To address the frequent occurrence of surrounding rock instability such as roof fall and rib spalling in roadways with weak interlayers at a working face of Wengfu Phosphate Mine, field investigations and FLAC3D numerical simulations were conducted, and the surrounding rock control effects of conventional bolt-mesh-shotcrete support and the composite support technology of "bolt-mesh-shotcrete+steel arch+advanced support" were systematically compared. The research results show that the weak interlayer contains 3.9% kaolinite, and expansion and softening after water immersion are the main causes of surrounding rock deterioration. The vertical displacement of the roadway is reduced from -8.33 mm to -6.67 mm by the composite support technology, with a decrease of 19.93%. The horizontal displacements in X and Y directions are decreased from 2.61 mm and -1.64 mm to 1.27 mm and -0.58 mm, with reductions of 51.34% and 64.63% respectively. The stress concentration is remarkably alleviated, and the total number of failure units is lowered by 13.82%. It is shown by field application that the average monthly accident rate is reduced from 0.6 times to 0.27 times, with a decrease of 55.0%. The large deformation of surrounding rock under multi-thin interbed conditions is effectively controlled by the composite support technology. A theoretical basis and key technical paradigm are provided for the safe excavation of roadways containing dense weak interlayers.

针对瓮福磷矿某工作面含软弱夹层巷道冒顶、片帮等围岩失稳现象频发的难题，通过现场调查与FLAC3D数值模拟，系统对比了常规锚网喷支护与“锚网喷+钢拱架+超前支护”复合支护技术的围岩控制效果。研究结果表明：软弱夹层含3.9%高岭石，遇水膨胀软化是围岩劣化的主因；复合支护技术使巷道竖向位移由-8.33 mm降至-6.67 mm，降幅达19.93%，X、Y方向的水平位移由2.61 mm、-1.64 mm分别降至1.27 mm、-0.58 mm，降幅分别达51.34%、64.63%，应力集中显著缓解，总破坏单元降低13.82%。现场应用表明，月均事故率由0.6次降至0.27次，降幅达55.0%。复合支护技术有效控制了多薄层互层条件下的围岩大变形，为含密集软弱夹层巷道的安全掘进提供了理论依据与关键技术范式。
