Abstract: At the Rio Tinto Pilbara iron ore mines of Western Australia, drill and blast operations use autonomous drills. These drills have automated control functions such as tramming (propulsion using tracks), levelling and drilling.
Identified areas are tagged, and then holes are drilled in an appropriate pattern by rigs. The drill holes are filled with an explosive, most often ANFO (Ammonium Nitrate/Fuel Oil) and then charged. The resulting blast breaks the material to a size required for digging.

It is well documented that drill and blast outcomes affect the downstream mining processes of loading, hauling, crushing and grinding but it can also significantly impact on mine profitability via dilution, recovery percentage, lump generation (iron ore), fines generation (coal, iron ore), coal loss and final wall stability.
Once the taconite rock is exposed, large drilling rigs drill blast holes 16" in diameter by 40' deep, in some cases. Nearly 400 of these holes are drilled in a blast pattern.
Effective blasting can deliver consistently fragmented, loose muckpiles of the optimum profile. Advanced blasting technology and clever blast design can improve the utilisation of the drilling fleet and reduce capital and operating …
Effective blasting can deliver consistently fragmented, loose muckpiles of the optimum profile. Advanced blasting technology and clever blast design can improve the utilisation of the drilling fleet and reduce capital and operating costs without compromising productivity.
Drill depths are accounted for more accurately, making it easier to assign the right amount of explosives in blasting. New GPS-enabled applications have improved strata recognition …
The drilling principle is to use a high pull down force (weight-on-bit), rotate the drill bit, and blow the rock cuttings to the surface with compressed air. Hardrock drills typically use the Rotary method to drill blastholes from 200 mm (7 7 /8") to 311 mm (12 ¼") diameter.
At their Australian iron ore mine, Roy Hill monitors excavator hydraulic and telemetry sensor data on an analytics platform. It provides insights to optimize motion, speed, and trajectory. Moreover, they have increased payload sizes and fill factors by smoothing out digging paths.
Advanced blasting technology and clever blast design can improve the utilisation of the drilling fleet and reduce capital and operating costs without compromising productivity. Matching explosive energy to geology enables expanded patterns without affecting fragmentation.
Yin & Thompson have led the implementation of the Stratalogger™ drill monitoring system in iron ore. Dance has described the implementation of the Aquila™ system in open pit copper. …
