Abstract: Slope slip has occurred at the highway outside the concentrate bin of Yichun Tantalum-Niobium Mine, where the hidden danger of slope slip still exists. Therefore, analysis is made of the formation mechanism of the internal factors, external factors and inducement of the slope slip and its characteristics, and also of the slope stability. Based on this, scheme comparison is made. The comprehensive control measures such as support and block, surface regulation of the slope mass, slope protection and drainage can ensure the safety operation of the concentrate bin of the concentrator.

Key words: Analysis of slope slip formation, Stability analysis, Comprehensive regulation
