1. Introduction. Mining activity is mostly represented by these four main operations: drilling, blasting, loading and hauling. For a proper mine planning and design, all of these operations need to be carefully planned in such a manner that can prevent extra loads such as operating costs, environmental footprints, etc. Amongst these operations, drilling and blasting are known as the pioneers ...

Appropriate blast design is important in order to lessen the production of over size. Secondary blasting can be done by pop shooting (blockholing) and plaster shooting (mudcapping). Shaped charges are sometime used in secondary blasting, but this is much more expensive. Cast Blasting When overburden is removed from a coal or mineral deposit it

Surface miners drive up savings in coal mining. Mine operators for some time now have been increasingly turning to an alternative to conventional ripandstack or drillandblast coal mining: the use of surface miners.
1. Introduction. Rock fragmentation distribution influences a range of mining and milling processes including load and haul rates, crushing and grinding performance and ore recovery in beneficiation processes (Michaud et al., 1997).In opencast mining, where blasting is employed for excavation, the overall cost effectiveness of the production operations is compatible with optimization of ...
Coal prices at surface mines are generally lower than prices at underground mines. In locations where coal beds are thick and near the surface, such as in Wyoming, mining costs and coal prices tend to be lower than in locations where the beds are thinner and deeper, such as in Appalachia. The higher cost of coal from underground mines reflects ...

Blasting is one of the most feared and least understood aspects of mining operations in Ohio and elsewhere. But on a typical workday, over a quarter million pounds of explosives are safely detonated in Ohio''s quarries and surface coal mines.
Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is .
