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.

H BLASTING IN SURFACE EXCAVATION

Blasthole diameter (D): Generally, the cost of drilling and blasting decreases as hole diameter increases. The relation between blasthole diameter and face height is approximately: D = 0.001 to 0.02 H Since iron ore is hard rock, and referring to Table 1 the rock factor A can be taken as 11. Assuming flyrock has to be controlled, Z=1.25.
