The study of failure status and treatment methods of open-mining rock slope in Chongqing

摘要

Open-mining forms high steep rock slope, slope stability is affected by geological environment, structure, stratum, lithology, hydro-geology, rock structure, structural plane appearance, slope azimuth with spatial combination relations. After mining the bared slope with weathering, due to heavy rainfall, earthquake and other factors causes secondary disasters and serious impact on people's life and property safety. This paper is based on a comprehensive investigation, statistic and classification of the status quo and failure patterns of the rock slope and treatment method is simulated and analyzed, pros and cons of various treatment methods were compared, to provide the decision-making reference for similar mines management, and basis of theory and practice, to build green mines and sustainable environment.
