Research on Deformation Mechanism of the Bedding High Rock Slope with Different Interbed Thickness at Jinning Phosphorus Mine

Shi Gang;Liu Huali;Liu Xuezeng;Shanghai Tongyan Civil Engineering Technology Co. Ltd;College of Surveying and Geo-informatics,Tongji University;  
Taking the bedding high rock slope of the eastern mining area in Jinning Phosphorus Mine,Yunnan Province as the research object,based upon the geotechnical exploration,this paper makes statistics and analysis on configuration,failure condition,the slide plane,and the slip mass of the landslides. And the deformation characters,mechanical mechanism,formation and evolution of these landslides were analyzed by geological and mechanical methods. Then,the deformation mechanism was checked by means of distinct element method. The results indicate that the main deformation and destruction mode of the bedding landslide is sliding-tension failure. The rainfall and phosphate rock mining is the important cause of landslide sliding. The exploitation of the phosphorus mine led to formation of some free faces due to cutting off the rock,it caused relax and cracking of the rock mass,and the completelyweathered clay layer gathered plenty of water due to that the rainwater infiltrated along cracks,and there is strong hydrate material,under long-term softening and different weathering,the rock mass strength was attenuating. The landslip slides along the soft slide plane,and the back rocks are pulled,the extension fractures and the soft slide plane appeared,and then the slope deformation appeared,and the main formation mechanism of the sliding-tension cracks was the rock's tension destruction,the main role of rock destruction is the tensile stress σ3. Analysis of the deformation mechanism of the slope from the displacement variation,deformation rate,sliding plane and stress distribution by discrete element method shows that the deformation is of sliding-tension type. The results can provide some reference for stability analysis and strengthening design of the slope at the mine.
