13.12.2018It is the most common drilling technique used for mining exploration, particularly in South America and Australia. RC drilling is a form of percussion drilling, by which the rock is made to fail through the use of a piston that delivers rapid impacts to the drill stem, transferring energy to the drill bit. These blows to the rock are delivered
