| Abstract: | According to the site condition of the No. 1304 working ace of a underground mine, by using flac 3D technique, simulate the developing principle of 3-D stress field in the case of large mining height and large dip angel. Studying the ore rock stress changing symbol of large mining height stope, also the mining wall damage and spaiing analysis.By using Numerical simulation software, research the mine wall stability in the case of large mining height and large dip angel ,and analyzing the relationship among Dip angle of rock stratum , stope height and spailing. |
