drill and blast processes in iron mining
Blasthole Sampling VS Reverse Circulation Sampling
Blast Holes and RC drilling have different objectives and use different metrics. Blast holes are very short hole on a very small grid (short spacing) compared to RC drilling. But the most important aspect is that Blast holes are oriented to meet explosive and other mine planning objective. RC drilling is designed to meet geological objectives.

Underground mining (hard rock) Wikipedia
A threedimensional model of a modern underground mine with shaft access. Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.
