Underground mining modifies the in situ stressfield and results in stress redistribution around the excavations. Depending on the mine geometry and geotechnical environment, failure of the surrounding rock mass can result in the release of seismic energy.
SCT has developed the field capability to study and monitor overburden caving behaviour above longwall panels. This capability complements and informs a range of control strategies using hydraulic fracturing that have also been developed.
