Justification of Bottom-Up Cut-and-Dry Fill Approach to Mining Gold Reserves under Open Pit Bottom

Journal of Mining Science Aims and scope

Abstract

The geomechanical conditions of underground gold ore mining in thin and steeply dipping ore body under open pit bottom are assessed using the dedicated 3D parameter-oriented model of mine design. The numerical model has produced the forecast stress pattern maps of ore and rock mass disturbed by mining operations. Stability justification is implemented for a sill pillar at a depth of 140 m in case of active stoping two levels above and below the pillar. Safe parameters and conditions are determined for the cut-and-dry fill mining operations.
