Drilling And Blasting Cost – Mining And Blasting. blasting is only the first step in the production process for mines and quarries and the costs of this first step is normally only 8% to 12% of the total costs. the total product costs are composed of: drilling, blasting, secondary breakage of oversize, digging, haulage, crushing. blasting affects every step in the production cycle.

2.3 Method of Mining The proposed captive mine project is a fully mechanized opencast mining project with 7.0 MTPA capacity. Conventional mining system with shovel dumper combination mining technology will be adopted. The sequence of the operations will be development of mine benches, drilling, blasting, excavation, loading,

At the end of the open-pit mining process in large metal mines, the mining model must change from open-pit mining to underground mining, but the mutual interference between the two mining models leads to poor production safety conditions and difficulties in production convergence during the transition period. To solve these technical problems of poor production safety conditions …
