Blasting Practices in Mining what you need to know

2021-4-6  Blasting in mining is a chemical and physical process that occurs through the firing of explosives. It breaks mineral-bearing materials. These materials can be coal, ore and mineral stone. Blasting fragments materials, splits off rock blocks, and demolishes existing structures. The process of blasting goes through blast design prior any

Explosives Used in Mining: Properties, Types, Transport

2022-2-6  Explosives differ widely in resistance to water and moisture penetration. Some explosives deteriorate rapidly under wet conditions, but others are designed to stand water long enough to enable the work to be done. When blasting is to be performed under wet conditions a gelatinous or slurry explosive should be used.
