Drilling and Blasting | Technical Aspects of Mining

Blasting in a mine generally occurs in two phases, primary blasting and secondary blasting. Blasting Primary Blasting is the activity in which in-situ rock is broken in both development and stoping and in surface mining by drilling holes in the rock, charging them with explosives and detonating the holes in a planned sequence.
