| Abstract: |
| The study on the stability of the goaf requires the results of rock mass evaluation and the rock mass mechanical parameters of the ore rock as the fundamental support. Through the field of engineering geology of rock mass structure surface sampling survey, core and indoor rock mechanics test, using four different methods for rock mass quality evaluation, learned that the marble, schist and ore body is moderate to poor rock mass, and the quality evaluation of conclusion as the next step the basis of studying the mechanical parameters of rock mass, with the hawk brown, the Moore cullen and the parameters and the parameters of the hawkes and didrich, and the conversion of the Canadian pro software RocLab, the mechanical parameters of the three different mines of the mine are calculated. |
