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.

mining - mining - Blasthole stoping: When the dip of a deposit is steep greater than about 55& 176; , ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough. At the end of the trough, a raise is driven to the drilling

Drilling and blasting - Wikipedia

A number of holes are drilled into the rock, which are then partially filled with explosives. Stemming, inert material, is packed into the holes to direct the explosive force into the surrounding rock. Detonating the explosive causes the rock to collapse. Rubble is removed and the new tunnel surface is reinforced.
