MWD For Super-resolution Control Of R.A.B. Drilled Blast-hole Stand-off Distances

Get Report
C1902301/02/2011
Author: Iain Mason | University of Sydney

Open-cut coal mine blasting losses are serious. Incorrect blast stand-off cost the equivalent of one unnecessary mine for every 10 existing Australian open cut mines. The 3D models now used to prescribe drill-bit direction are constrained in accuracy by pierce point affordability until ....  read more

RAB Drill Rig Top Of Coal Detection While Drilling

Get Report
C2100516/11/2015
Author: Enver Bajram, Daniel Hudson & Scott Adam | CRCMining

Accurately detecting the approaching top of a coal seam prior to blasting is fundamental to efficient coal recovery. Previous investigations by member mining companies reported a 66% reduction in coal dilution through disciplined and detailed overburden drilling and blasting practises. Through ....  read more

 

Slotting While Drilling for Reduced Blast Damage to Coal Seam: Stage 2

Get Report
C1405601/05/2007
Author: Matt Stockwell, D Tadic | CRCMining
