Stability Evaluation and Cooperative Monitoring Analysis of Open-pit Slope in Henan Province
The safety problem of high steep rock slope in large open-pit mine is becoming more and more prominent,so it is of important significance to carry out regional stability evaluation and collaborative monitoring analysis of slope.Taking a molybdenum mine in Henan province as the research object,a de-tailed engineering geological survey and slope zoning are carried out.According to the results of slope stabili-ty analysis,online real-time monitoring of potential risk areas is carried out to study the slope deformation rule under the action of continuous rainfall.The results show that the safety factor of A2 area under the influ-ence of dead-weight,groundwater and blasting vibration is 0.971,which has potential landslide risk.Rain-fall is the main adverse factor affecting slope safety,and the shallow slope deformation caused by continuous rainfall is the main cause of slope instability.
