通过总结近些年研究所取得的成果,结合数值模拟和现场实践经验,重点分析了充填材料力学性能、墙体几何参数、顶板岩层结构、回采速度等因素对巷旁墙体结构稳定的影响机理及效果,得出高水速凝材料和膏体材料充填墙体具有很好的承载特性、不同地质条件下墙体宽度最优值不同以及施工质量等对巷旁墙体稳定性会产生很大影响等结论。
By summarizing the achievements made in recent years, combined with numerical simulation and field practical experience, the paper mainly analyzes the influence mechanism of mechanical properties of filling material, wall geometry parameters, roof rock strata structure and recovery rate on the stability of roadway wall structure The results show that the high-velocity concrete and paste material filled wall has good bearing characteristics, the optimum width of the wall under different geological conditions and the construction quality will have a great effect on the stability of the roadside wall Impact and other conclusions.
