Strata Consolidation is a necessary procedure to solve geological problems in mining and tunneling.
For example, unstable and loose rock can lead to excavations, convergences, or subsidence at the surface during drivage or roadway heading. The specific nature and composition of the rock dictate how the mining excavation must be designed.
This difficulties can arise because of the properties of the rock. It is therefore important to ensure that, after the rock has been excavated in the mining progress, there is no critical relaxation and thus loosening of the surrounding rock. Therefore, initial securing measures immediately before or after excavation are indispensable.
The use of injection products leads to a rehabilitation of the rock stress, and the relaxed rock regains the required stability.
