Selection of practical bench height in open pit mining

Key words: Open pit mining, bench height, multi-criteria decision making. INTRODUCTION As a definition in open pit mining, bench height is the vertical distance between crest and toe of the bench (Fourie and Dohm, 1992). Determination of optimum bench height is a major concern in most open pit

Open pit mining SlideShare

Jul 31, 2017 Open pit mining The ores in an open pit mine are covered by overburden. Both the ores and overburden are removed in benches ranging from height 9 m to 30 m. A thin deposit may require one or few benches but a thick deposit needs more number of benches and the pit in its production stage resembles like an inverted cone. 4.

Major Mines & Projects Boroo Mine

The Boroo deposit was mined using conventionalb open pit mining methods. Mining was done with bench heights of five metres, with ore mined on half-benches for improved grade control in the flat lying ore. Three to four benches were typically under development at any given time. Blast hole drilling was carried out with two rotary-percussion

Open-Pit Mining Methods

Apr 09, 2017 The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit-wall slopes must be such as to prevent sloughing of overburden onto the ore area. Where the ore is to be hauled from the pit by locomotive or trucks, additional excavation is required to provide an approach on a grade suitable for haulage
