ABB mining robot has a blast with automated charge handling

The ABB Robot Charger uses a combination of machine vision, automation and precision robotics to identify boreholes in the rockface, then prime them with explosive charges and detonators. According to ABB, the system can be retrofitted to any truck, with the robot deployed to multiple blasting sites over the course of a day.

Blasting schedules in mines vary widely, but in some mines can take place up to 15 times per day. Currently, setting charges is one of the last remaining mining processes that is fully manual, with miners working at unsupported rockfaces. ABB said the Robot Charger will be a leap forward for mine safety, automating this potentially dangerous task.

“This is a significant technology development for ABB and the wider industry where safety is part of overall ESG commitments,” said Vedrana Spudic, head of Technology, Business Line Mining, ABB.

“The robot locates the drilled holes on the rock face using a vision system, and these recent tests show all can be reached and charged with the cycle fully automated. This removes the need for human operators in a small, unsupported area right at the face.”
