In shovel dumper coination system the main objectives are To increase the productivity and to reduce the time of operation. These are done by: Minimizing shovel wait time (MSWT): The empty truck in this objective is assigned to the shovel which will be

In pit crushing and conveying in surface mines

With the increase in depth of working, generally the unit cost of drilling & blasting remains unchanged, whereas, the unit cost of transportation by dumper for both the ore and waste increases, and the rate of increase in unit transport cost also increases with the increase in depth.

The Volksrust formation shale shows an increase in carbon content with depth and varies from a massive bluish- grey mudstone to carbonaceous shale towards the base. Although the thickness and coal quality of the Volksrust formation are reasonably constant across the coal field, a large variation in the yield of semi-soft coking coal and total sulphur content occurs vertically in the coal

Selection of Open-Pit Dump Trucks during Quarry

1/1/2017· Nowadays and in the near foreseeable future the quarry road transport will be the most common in the open-cut mining method. This is due to a range of advantages of open-pit dump trucks usage as compared with other types of quarry transport, i.e. autonomy, the possibility of using in any mining engineering and climatic conditions etc.

Study on Buffer Zone Optimization between Open Pit and Dumping in Erdenet Mine in Mongolia alongside the pit also gives an advantage to waste hauling cost. However creating a waste dump alongside the pit should be planned well thus it does not give worse affect to pit planning of the mine depth and amount of the waste dump material.
