Geomechanical conditions of gold mining in Charmitan Mine

Charmitan Gold Mine is rockburst-hazardous, which requires geomechanical assessment of mining conditions. The investigation used the method of geodynamic zoning. The block structure and the behavior of rock mass blocks are determined, and the stress state of rock mass is modeled with identification of high concentration areas of tectonic stresses. Three jointing systems are distinguished. The implemented prediction says that roadways driven along the strike of longitudinal and diagonal cracks, or cutting the cracks at skew angles are the least stable, especially in the high concentration zones of stresses. The research results are usable in project designing and in development of recommendations on safe deep-level mining.

Keywords: Charmitan Mine, rockburst hazard, geodynamic zoning method, rock mass, stress state, jointing, safety, mining.
