摘要
为解决双侧沿空留巷开采技术中所面临的支护困难、围岩破坏严重以及稳定性差的问题,在对8号煤层顶底板条件分析的基础上,对其煤岩顶底板的力学参数进行测定,并针对巷内和巷旁分别提出了支护优化方案,为后续双侧采空沿空留巷开采技术的推广应用奠定基础。
In order to solve the problems of difficult support,serious damage to the surrounding rock and poor stability faced by the double-side airside lane mining technology,the mechanical parameters of the top and bottom slab of coal rock were determined based on the analysis of the top and bottom slab conditions of the No.8 coal seam.Through the actual problems faced by the current in-road support and alongside-road support,the support optimization plan is proposed for the in-road and alongside-road respectively,laying the foundation for the subsequent promotion and application of the double-sided mining along-road mining technology.
