摘要
阐述了地下采场顶板破坏的机理和防治方法,根据顶板岩层的破坏条件,利用数值分析方法对铅硐山矿地下开采的矿岩稳定性进行了研究,并对地下采场结构尺寸进行了调整,有效地解决了顶板冒落,保证了地下矿产资源安全高效地回采。
The mechanism of the roof failure of underground stope and countermeasures against the failure were described. According to the conditions under which the roof stratum breaks, a numerical method was applied to analyzing the stability of rock mass during the underground mining in Qiandongshan. The structure dimension of the underground stope was adjusted, effectively solving the problem of roof inbreak. The research results provide a guarantee for safe and effective stoping of underground mineral resources.
