Abstract: After 40 years' mining in Maluping mine of Kaiyang Phosphorus Mine Group,some of its level positions are coming into the deep mining. In order to predict the orientation of rock-burst for four kinds of rocks in 750 level,700 level and 600 level respectively,the systematical experiments for the four kinds of rocks have been performed. At the same time,various evaluation criteria on the different influence factors were put forwards. And the theoretical prediction method was used to realize its fuzzy mathematics evaluation of rock-burst. At last,the level-variables Eigenvalue was used as the judge criteria to estimate the orientation of rock-burst in three level sections for these four kinds of rocks,and it is concluded that the rock-burst tendency will be up with the depth of these four rocks increase.
