摘要:

根据新城金矿顶底柱开采的技术条件,应用极限分析法导出了人工假顶最大变形量和水平临界载荷计算式,并据此对新城金矿顶底柱开采稳定性进行了监测。试验研究期间,运用YZY型应变式刚性钻孔应力传感器、收敛计分别对回采过程中岩体内应力变化、进路的收缩变形进行实测,为类似条件下矿柱开采的稳定性监测探索出一种行之有效的方法。

关键词: 人工假顶, 稳定性, 变形极值, 临界载荷, 监测, 新城金矿

Abstract:

According to the technological mining conditions of the roof and bottom pillar in Xincheng gold mine , the calculation formula of maximum deformation and horizontal critical load on artificial roof have been deduced by applying limit analytical method. The stability of the roof and bottom pillar has been monitored. During the test , the YZYof drilling hole st ress sensor with st rain and rigidity and the ast rictive meter have been used and tested separately the variation of st ress in the rock and the cooling strain in the drift road. A effective method has been t racked out for monitoring the stability of the analogical pillars.

Key words: artificial roof, stability, maximum deformation, ext reme load, monitoring
