Abstract	Slope height gradually increased with the increase of mining depth. While the probability of slope instability and the difficulty of preventing a growing stope from destruction give mine a huge security risk and economic losses. By means of the slope simulation experiments we can directly observe and record the deformation, damage evolution of the object and each stage of the deformation of the stress can be obtained in stress analysis. Analyzing the stability of slope in 2-2 profile of Luming molybdenum West-I district by a similar simulation has these advantages: intuitive, clear, short test cycle and low-cost. And some important factors hard to be considered in calculating mathematical analysis can be considered. First, get the ratio number of each simulation stratified by similar material ratio test. Followed by the establishment of a similar model and simulating the excavation process, directly observing and recording the displacement of test model with every step of the slope excavation as well as the stress changes of strain gauges. Through the analysis of experimental data, a conclusion is drawn: stress concentration is most likely to occur in 180-meter platform and 240-meter platform located in F3 and F4 fault. And they should be a priority in slope monitoring and reinforcement of governance. The study plays a role to protect the safety of Luming molybdenum production.
