FRAMENTATION - THE VITAL LINK IN THE DRILL TO MILL PROCESS INFORMATION SYSTEM

CIM MineSpace 2001
Abstract Both hard rock and coal surface mines have been pursuing a drill to mill (or coal plant) process information system: drill - blast - excavate - haul - dump. Until now the tools have not been available to link the drilling and blasting techniques to the ease of excavation. However, today drill navigation is the tool that records for the mine where every hole has been drilled and to what elevation above sea level. Drill monitoring records for the mine how difficult the rock was to drill by associating a rock index to every few centimeters of drilling. Lastly electric shovel monitoring and dragline monitoring records for the mine the ease of excavation of every dipper / bucket and supplies, using GPS, the source location of every dipper / bucket as well. Hence the wisdom of the drilling and blasting techniques adopted are verified by the ease of excavation. Comparing drilling and blasting to ease of excavation has only become simple for engineers to do with the advent of onboard PC based tools linked to GPS receivers. Diggability maps graphically displaying the results of excavating a whole drill pattern are available in the office with a few mouse clicks.
