Mining production system consists of drilling, blasting, loading, hauling and crushing subsystems. The mean fragmentation size is related to the cost of all subsystems. To minimize the mining cost, the relation between the mean fragmentation size and the cost of each activity should be analyzed. The total mining cost of a bench (C M), consists of

The production process in a mine is divided into four parts of drilling, blasting, loading and hauling. The later two aspects i.e. loading and hauling allocate more than half of the total mining cost. The cost related to purchasing loading equipment is more than the vehicles needed for other sections.

Drilling. Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases, in the ASM sector, by hand, using a hammer and chisel. This is obviously tedious and slow, especially in hard-rock mining conditions.

Rock blasting for mining - SlideShare

21 This diagram illustrates the overall organisational structure of a mine cycle. Once the ore body is investigated through detailed surveys, the next steps include drilling and blasting, followed by loading, hauling, primary crushing and other ore-dressing operations. Blasting helps in not only in rock breaking, but also in primary crushing.

A system-wide approach to minimize the operational

12-12-2018  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 the total mining cost of bench production.
