SCT Operations (Strata Control Technology)

Computer modelling provides a method of simulating overburden caving due to longwall extraction. The computer modelling methodology has been validated in ACARP studies and papers. Computer modelling of caving provides outputs for single and multi-seam extraction in areas of:

  • Surface subsidence
  • Mining induced fracture network
  • Stress redistribution
  • Pillar stability
  • Pore pressure
  • Multi-seam interaction
  • Caving behaviour

Computer modelling of longwall caving is based on site specific data of mine geometry, stratigraphy, lithology, extraction height and extraction method. This provides the ability to conduct parametric assessments for mine options assessments and sensitivities of the caving system.

Results from longwall caving models provide mine design outputs used in feasibility studies and operational mine investigations.
