Research On Steep End-slope Technology Of Antaibao Surface Coal Mine

Due to the end-slope involve the safety of the open-pit mine slope form,also closely connected with the economic benefits of open-pit mine,so the help stability problem is one of the focus of the researches on the strip mining.According to different engineering geological conditions of open-pit mine,the design meet the requirements of side slope in form,it is the guarantee of the basic elements of open-pit mine maximum recovery of coal.Paper to Antaibao open-pit coal mine side slope as the research object,using the site investigation,open-air mining theory knowledge,limit equilibrium method and numerical simulation method,in combination with rock mass mechanics parameters,selection of the mine end for typical geological section,on the slope stability and landslide mechanism and so on question has carried on the thorough research.Fort on the analysis of the Antaibao open-pit mine is the formative characteristics of slope in end-slope,based on the investigation,the occurrence condition of the mine end help structure surface collected end for rock specimens for point load test,combined with Antaibao open-pit coal mine geological data,determine the physical and mechanical parameters for rock and soil body.In a typical engineering geological section as the research object,analyzes the relationship between slope Angle and slope stability,sure can meet the safety coefficient of slope angle;Under the condition of different pressure for high slope stability are analyzed,the reasonable pressure for height.Slope stability before and after the pressure for the numerical simulation research,determine the destroy of slope rock mass,and reveals the mechanism of the landslide.
