Development of mix designs for the production of backfilling materials
Services
- Development of mix designs for the production of backfilling materials based on industrial wastes for hydraulic methods and mechanical methods (drop backfilling and backfilling with big bags) including
- Determination of the permissible operating range according to the ordinance on the health protection in mining
- Adjustment of the necessary parameters of the process technology (rheology, processing time, dust formation)
- Rejection of heating effects and the gas formation
- Detection of the geo-mechanical suitability
- Detection of the tolerance against the host rock
