Monitoring rock mass transformation under induced movements

The article reports the underground mining-induced movement monitoring using a combination of geodesy survey and geophysical exploration methods in Vysokogorsky Iron Ore Mine where a geodynamic movement has occurred. The geodesy survey methods are the conventional observation of the daylight surface deformation and the spectral seismic profiling of changes in the undermined rock mass structure. The monitoring objective was to find spatial parameters of disintegrated rock zone, to make recommendations on continuing mining operations in the subsidence trough zone where protected objects are situated, and to identify causes of the enclosing rock instability.
