Abstract: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.
Keywords:numerical method  stope size  roof failure  underground mining
