Blasthole Cone Sampling Experiments For Flitch Mining

2002 due to the shallowhole nature of the drilling application in mining drill bit advancement is not steerable and therefore not as dynamic as in oil and gas for these reasons realtime drill bit positioning would be redundant in the mining industry so long as the drill unit is leveled and in position over the desired blasthole location.
