摘要
采用工程地质力学方法、岩土工程实验技术和有限元数值分析计算方法,综合研究了某矿Ⅱ号矿体7-9线-55m中段以上采区系统的稳定性和采场结构;改进和优化了采场结构参数,确定了合理的回采顺序和回采方案,从而保障了在该矿采掘过程中的安全性和可靠性.
In this paper, engineering geomechanics, the technology of geotechnical engineering and the finite element numerical method were used. The stability of system and the mining technological data above -55 meters lever in 7-9 line of some mine II ore-body was researched. The improved and optimized mining technological data was brought forward. A good sloping sequence and project were made to project the security and reliability in the process of excavation.
