| Abstract: |
| on account of the conditions of engineering geology and mineral deposit in a mine, the basic idea of this paper is to determine the limit exposure area of the stope, the structure parameters of the stope are optimized according to the results. First of all, the maximum exposure area of the mining field was preliminarily determined by using the Mathew stable chart method and According to the orthogonal numerical simulation test, work out the mechanics of mining field under different exposed area are obtained. The conclusion is analyzed by two methods, the two kinds of data can be verified and make comprehensive decision, with a more comprehensive way, the parameters of the mining structure are optimized. |
