Sep 05, 2013 This paper presents an approach to waste dump site selection in open pit mines using the integration of multiattribute decision making (MADM) methods. Different MADM methods often produce different outcomes. To make the best decision for dump site selection, the results of subjective and objective MADM methods are considered for a final decision.

There are two waste dumps in close proximity to the two open pit mining operations. The paper covers the slope stability analysis of the active dump as mining expands and the dump develops further. A phased rehabilitation programme will be implemented on the inactive dump. A layout of the open pits and the waste dumps is shown in Figure 1.

Generally, an open pit mine has a higher stripping ratio than an underground mine. Waste rock is often deposited in piles or heaps close to the mine to minimize transports. As waste rock is exposed to air and water, a weathering process will proceed. Weathering of waste rock could contribute to the generation of an acid drainage (called acid ...

Rock or Solid Mine Waste. Open pit mining has several stages of waste. First, to access the actual seams or veins of ore, the top layers of rock or overburden must be removed. Once the overburden has been removed, the seams can be extracted. When extracting the seams, there is additional waste rock that must be separated from the ore.

Oct 26, 2016 There was also limited capacity to move large quantities of materials and so the waste generated was discarded within a few meters of the mine opening or pit. Open-pit mining produces eight to 10 times as much waste as underground mines because a greater amount of topsoil, overburden and barren or waste rock has to be removed.

The mining waste of open pit mines is usually piled-up in dump sites, making a man-made hill more than tens of meters high. Because of the loose structure of the dump sites, landslides or debris flow may occur after heavy rainfall, threatening local lives and properties. Therefore, dump stability analysis is crucial for ensuring local safety.
