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.

2016125Abstract The issues concerned with slope stability in the open cast mines have come to forefront in the mining operations due to increasing pit depth. The cut slope stability has the most prominent influence in the productivity and longevity of a mine collapse of which can lead enormous damages to man and machinery.

In other words a quarry is a big manmade hole in the ground from where minerals or rock are taken out. Quarries are made when big deposits of commercially helpful minerals or rock are found close to the Earths surface. Quarrying is a type of mining and is also called as open pit mining or strip mining.

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
