Slope Design and Implementation in Open Pit Mines

2012-1-1  This article reminds the principles of slope design in open pit mines, and presents techniques and tools available to address the successive stages of slope design. Their practical implementation is then illustrated by two case studies of open pit mines. * Corresponding author. Tel.: +33 1-6469-4813; fax: +33 1-6469-4711.

SLOPE STABILITY ANALYSIS OF WASTE DUMP IN

Abstract This paper presents the slope stability analysis for the current as well as projected (final) geometry of waste dump Sandstone Open Pit “Osielec”. For the stability analysis six sections were selected. Then, the final geometry of the waste dump was designed and the stability analysis was conducted. On the basis of the analysis results the opportunities to improve the stability of

PREDICTION OF SLOPE FAILURE AT LETLHAKANE MINE

2006-3-22  is 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.

SLOPE STABILITY ANALYSIS FOR OPEN PITS 1

2018-9-21  Analyses of a deep wall in an open pit mine in the Peruvian Andes are used to compare limit equilibrium methods (SLIDE) with distinct element methods (UDEC) when the stability is controlled by rock mass strength. The pit wall has an overall slope angle of 37º and a height of 600 metres with an inter-ramp angle of 45º.

DESIGN OF STABLE SLOPE FOR OPENCAST MINES

2009-5-18  Slope stability analysis forms an integral part of the opencast mining operations during the life cycle of the project. In Indian mining conditions, slope design guidelines are yet to be formulated for different types of mining practices and there is a growing need to develop such guidelines for maintaining safety and productivity.

Pit wall optimisation and effective wall management

The requirements for open pit wall optimisation are often reliant on the drive for maximum ore extraction while maintaining the stability of the individual benches and overall slopes. In a very basic sense, slope optimisation can mean increasing the slope angles and/or bench heights and deepening of the pit against the original design with an objective to integrate the allowable factor of safety into the mine planning. This exercise comes along with the implementation of effective wall management practices such as attaining operable berm catch capacity, drill and blast design practices and procedures that address poor batter condition. The optimisation of pit slopes to achieve a steep deep pit and still maintain slope stability is often seen as challenging without the integration of batter steepening trials within selected geotechnical domains to understand if the rock mass can support the steep slope

Analysis of a slope failure in an open pit mine using

In 1996 a slope failure occurred at the Round Hill open pit mine, operated by Macraes Mining Company Ltd. The failure as shown in Figure 1, involved three benches at an intermediate slope that was being pushed back towards the final high wall location.
