Abstract

For profitability steep overall slope angle is essential for openpit mines without endangering the safety for the life time of the pit. Openpits have been designed to depths of 150 to 200 metres. For optimum slope angles of the footwall and the hanging wall of a rock phosphate mine, near Udaipur, Rajasthan , geotechnical investigation covering discontinuity mapping, analysis of data, testing of geo-mechanical properties in laboratory and in in-situ condition were conducted. Slope monitoring was done by precise surveying instruments to give advance warning of impending ground movement. On the basis of geotechnical studies the mine has been designed with an overall slope angle of 33 degrees up to 200 metres depth.

Openpit Mine Slope Stability – A Case Study

For profitability steep overall slope angle is essential for openpit mines without endangering the safety for the life time of the pit. Openpits have been designed to depths of 150 to 200 metres. For optimum slope angles of the footwall and the hanging wall of a rock phosphate mine, near Udaipur, Rajasthan , geotechnical investigation covering discontinuity mapping, analysis of data, testing of geo-mechanical properties in laboratory and in in-situ condition were conducted.
