Abstract:

Blasting at the rock face is one of the few manual processes left in mining. This is a typically dangerous phase of mining, it requires people to be present for charging explosives at the unsupported rock face, meaning they are exposed to rock bursts.

The Robot Charger technology automates charging at the rock face, meaning that humans no longer need to be present in this part of the mining process. The robot charger can be remotely controlled, safely charging the bored holes without the need for human intervention.

The new technology is developing in close collaboration with Boliden and LKAB and it helps put the end user in control but also with explosive supplier Forcit and LKAB Kimit. The Robot Charger technology comprises vision system and automation solutions which communicate with both truck and crane as well as the ABB industrial robot arm.

The robot is fitted to a charging carrier vehicle, which enters the mine face, detects boreholes, and fills them with explosives and detonators. The solution can be retrofitted to an existing truck, making adoption seamless for customers and the incorporation of a second robot arm which assembles detonators and primers, ensures automation of the full charging process and full reach to all boreholes and areas of the rock face.

ABB will present this new technology, technology steps and results from on-site tests in Boliden and LKAB mines.
