A system-wide approach to minimize the operational cost of

The production cycle of open-cast coal mines generally includes drilling, blasting, loading, hauling and coal preparation activities. Individual optimization of these activities does not mean that the whole system is optimized. This paper proposes a cost model considering all activities in mining cycle and system-wide approach to minimize Finally the coal is further conveyed to a 2-station train loading system.

In-Pit Crushing & Conveying Insights from IPCC 2012

The advantages of In-Pit Crushing & Conveying, in the right context, are irrefutable. In this month's Spotlight Feature Article, from the pages of the January issue of International Mining, Editor Paul Moore reports on IPCC 2012 in Bali, an IM Events conference. The conference highlighted current progress with record orders for IPCC ABSTRACT Three transportation systems In surface coal mines; 1- Truck Haulage. 2- Belt Conveying, and 3- Coarse-Coal Slurry Transportation are compared from the operations and cost points of view. Computerized design and cost models were developed and cost data banks were compiled for each system. These models can be used to evaluate Comparative economic analysis of transportation systems in surface coal
