Abstract

Deepening of Chadormalu Iron Mine pit is important from the planning point of view. This paper aims to re-evaluate the pre-designed slope angles of Chadormalu Open pit. In order to update the geological model of open pit and for determination of geological and mechanical properties of rock mass, geotechnical mapping was performed. After obtaining the updated vertical and horizontal planes of open pit, the stability of slopes was investigated using experimental, analytical and NUMERICAL METHODs. MRMR CLASSIFICATION was first used for estimation of primary slope angles. Then, the resultant sections were analyzed using analytical methods. Finally, the stability of the slopes obtained from analytical method was re-evaluated by using a Finite Element Code. Results showed that the inter-ramp slope angle of 55 degrees is not stable in some parts of the pit. Depending on the rock type, the safe slope angles in Chadormalu pit are suggested between 30 to 55 degrees.
