STUDY ON JOINT ROCK MASS FEATURES OF SLOPE IN SHUICHANG IRON ORE MINE

Study on rock features is premise and basis for mining project design and research.Selection of rational mechanical parameters of rock is very important for safety and economy of engineering.Based on probability analysis of joint rock mass features of slope in Shuichang Iron Ore Mine,a probability model for parameters selection is established.Quality class and macro mechanical parameters of rock mass in Slope are also assessed by means of SMR classification system which is suitable for the case.
