Drilling and Blasting Technical Aspects of Mining

Drilling. Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases, in the ASM sector, by hand, using a hammer and chisel. This is obviously tedious and slow, especially in hard-rock mining

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.
