Sensors for Precise Underground Localization
Important results from the project
The main goal of this project was to evaluate the feasibility of an onboard sensor to enable precise localization of a machine in an underground mining tunnel. We performed this evaluation by integrating several sensor and an industrial computer on a mobile platform and scanning an underground mine. The preliminary results showed that there is a large variance between techniques, with some laser-based localization methods showing promising performance.
Expected long term effects
We expect that in the long term the project will enable further research on underground localization and result in technology that allows machines to navigate autonomously. A future system based on the data collected and concepts developed would allow an operator to control a drilling rig remotely, something that is difficult to do today, due to the sub-centimeter localization precision required for drilling operations.
Approach and implementation
The project was carried out according to the initial time plan. We were able to collect data, as planned, within the first 4 months of the project, and spent the remaining two months analyzing. We decided not to do a second data collection at Boliden, resulting in a slightly lower participation rate of the end user. The collaboration worked well, with monthly management meetings, and frequent technical discussions. Engineering support by Epiroc was particularly valuable to the end result.
