Stability analysis of open-pit mining slope in metal mine
In order to realize that mining enterprises can provide a steady supply of mineral resources for the market economy,it is necessary to reasonably control various factors affecting mining in order to ensure the smooth progress of mining work.In open-pit mining of metal mine,the stability of slope directly affects the safety factor of mining,directly causes the stagnation of mining work,and even causes major safety accidents,which endangers the life safety of mining personnel.Based on this situation,the open-pit mining method of metal mine not only improves the mining speed,but also aggravates the problem of slope instability,which poses a threat to the economic benefits of the mine.In the research process,a certain metal mine is selected as the basis.The overlying rock in this mine is covered by quaternary aeolian sand,and the surface loess joints are developed,which is easy to form cracks or even landslide geological disasters.In addition,most of the geological layers in the region are composed of conglomerate and sand conglomerate.Causing frequent instability.At present,the whole mining area is in the stripping and mining stage.With the acceleration of mining work,more and more areas have not carried out construction operations and are increasingly affected by weathering.It is urgent to analyze slope stability and find out scientific and reasonable slope reinforcement methods,so as to improve the stability coefficient of slope and ensure the smooth development of mining work.
