Failure Mode Analysis And Risk Zoning Of Slope In Changshanhao Gold Mine

In the mining process of open-pit mines,geological disasters such as landslides and collapses caused by slope instability often cause strong damage and losses.This paper takes the Changshanhao Gold Mine as the research area.In recent years,after the Northeast Mine and Southwest Mine were transferred to deep mining,it has been many slope damages of varying degrees,which seriously threatened the safety and economic benefits of open-pit mining operations.The study area is divided according to the different danger levels of the open pit slope,which plays a guiding role in the safety protection and landslide warning of the open pit slope.In recent years,in the face of serious landslides in the study area,the pole analysis method is used to judge the failure mode of the slope in the study area by comprehensively analyzing the engineering geological survey data and statistical results.By analyzing the geological characteristics,six influencing factors of slope risk are selected,and the weights are calculated by factor analysis.The k-means clustering analysis method based on SPSS software was used to analyze the quantitative values of the risk factors of the study area,and the area was divided according to the different degrees of risk,and then the dangerous zoning map of the stope slope was drawn.By comparing the areas with different risk level and the actual situation of the stope slope,it is concluded that most of the slope failure occurs in the extremely dangerous area and the dangerous area,which verifies the rationality of the dangerous zoning results.This proves that the k-means clustering analysis method based on SPSS has practical value for the research on the dangerous zoning of open-pit mine slopes.The result can provide some reference for the reinforcement design of the slope.It can provide a reliable basis for the safety production prevention and control of the research object.At the same time,it provides a theoretical basis for the slope failure modes of other mines,and provides a method reference for further research on related topics such as the division of slope danger zones and risk assessment in other mines.Figure 55;Table 28;Reference 59...
