| Abstract: |
| The stability conditions of ore and rock are the important factors restricting the adoption or not and efficiency of stage backfilling method. Among this, the stability of local broken zone of ore contacted with rock has a serious impact on the stability of overall stope. In this paper, it was taken for engineering background that the test blocks with filling method of the western area in Jinshandian Iron Mine. Based on indoor rock mechanical test, combining GSI surrounding rock classification system, Hoek-Brown strength criterion, M. Georgi method and Γ.ΦИCEHKO method, the test parameters were reduced to more reasonable mechanical parameters of rock mass for the stability analysis and the support design of stopes with the way of rock mechanics. |
