How might we crush rocks in a more efficient way than today
Rock crushing & Preparation in Iron-ore Mines
Working in a mine is a hard job. It also is quite dangerous. After blowing up explosives to loosen rocks inside the mine, the LHD collects and brings the rocks to a Rock Breaker, which is taking its time to place and break rocks. Could this be a more efficient process? - Yes, it can. With the MRC15, a combined force of the LHD and the Rock Breaker.
A TRIP to the biggest iron-ore Mine in the world - Kiruna
After a nearly 9 hours ride we arrived at Kiruna, to get a broad overview of the mine and to hear about the situation and problems that mine workers have during their work. This project was carried out in collaboration with ATLAS COPCO and LKAB.
- Interviewing to mine workers
- Introduction to machines
- Introduction to equipment
- Tour guide through mine
- Presentation von LKAB & Atlas Copco
We visualized the mining process in Kiruna and presented the interviews we had with mine workers. Hereby we already analyzed problem areas, open questions and possible solutions. Our priority was to document what was going on, where the users were working and exploring their daily tasks.
For the different research phases we worked in teams, afterwards each of us decided on their personal area of interest to develop a concept.
The mining process - How it is today vs. a more efficient process
Increased efficiency with combined Loading-Crushing-Dumping
While working with different design methods, the shape of the Mobile Rock Crusher developed. The hydraulic arms collect the rocks, while - at the same time - the rocks get transported over conveyor belts inside the body and getting crushed. When they achieve the proper size (0.5m), they get dumped onto the oncoming trucks.
