Prediction Of Slope Failure At Letlhakane Mine

2006322is planned to continue with the open cast mining system until a depth of 400m below surface. Deepening of the pit and mining of Sandstone waste rock has brought about geotechnical challenges the most critical being slope stability. In order to manage the slope failure risk better a Geomos slope monitoring system has been installed at the mine.

Shear Strength Parameters For Assessing Geotechnical

Abstract As open pit coal mines venture to previously unchartered depths the importance of ensuring the geotechnical slope stability of high spoil piles becomes critical. However a reasonable understanding of material parameters under the high stresses involved is yet to be achieved. Of particular interest is the necessity and effectiveness of testing scalped specimens in the laboratory and
