The Hidden Weapon for Cost Reduction: Lifecycle Management of Jumbo Drill Tools Based on Cost Per Meter (CPM)
Under relentless pressure to reduce OPEX (Operating Expenses), mine procurement departments frequently tender drill bits and rods based solely on the lowest unit purchase price. However, in the context of mechanized underground drilling, rock tools follow a classic "Iceberg Cost Model..

Ending Frequent Rod Breakages and Stuck Drills: The Complete Manual for Jumbo Drill String Maintenance and Failure Analysis
In modern mechanized underground mining, the hourly owning and operating cost of a twin-boom or three-boom jumbo drill is astronomical. When a jumbo is sidelined at the face because a drill rod snapped inside a 4-meter hole, or the drifter is struggling to pull a stuck string, the financial loss is not merely the $200 cost of the broken steel..
