Study On Steep-slope For Cross Exploitation And Inner Dumping In Zhalainuoer Surface Coal Mine

For seam open-pit mine, adopt cross deep steep slope mining in row tracked mining technology can be meet the slope stability under the premise of maximum recovery of top coal slope in pressure. Ranked top paper to jalainur opencast mine horizontal mining slope as the research object, the integrated use of field research, theoretical analysis and limit equilibrium method and numerical simulation methods and means, on the slope stability and landslide mechanism and so on question has carried on the thorough research.Based on the analysis of slope engineering, on the basis of geological characteristics, determines the influence factors of slope stability and potential landslide model. Combining jalainur open-pit coal mine in the past test results, the slope rock mass physical and mechanical parameters is determined. In a typical engineering geological profile as the object, calculation of the slope stability of various geological section, 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.
