Stability Analysis And Controlling Of The East Slope In Yimin Open-pit Mine

In this article ,We studied the stabilization and controlling-exploitation of slope distorting region which is in the east slope of the strip mine belonging to The Yimin coal-electricity company .We obtained detailed and credible basic data through studying the condition of engineering geology water geology and the intension of rock .We also studied the mechanism of the slope distorting region using the examination on the bottom friction and numerical simulation (ANASYS 5.5program) and provided the distorting-breakage pattern ;on the basis of applying the SARMA's program which is used to calculate the stabilization of slope .we designed the controlling-exploitation scheme using the rheology theory of soft rock .We also analysed the correlativity about exploitation and distortion observation displacement distorting speed and the quotient of stabilization.
