Underground mine planning: stope layout optimisation under grade uncertainty using genetic algorithms Int. J. Min. Reclam. Environ. (IF 1.917) Pub Date : 2018-06-18 Martha E. Villalba Matamoros, Mustafa Kumral
Stope layout optimisation finds a technically producible orebody portion that maximises the profit of the mining operation based on the stoping method used. A three-stage stochastic optimisation model combining genetic algorithms (GA) is proposed to account for grade uncertainty. The first stage computes the stope layout uncertainty, the second stage creates average design and their feasibility evaluation

Dynamic simulation of the sudden settlement of a mine waste dump under earthquake loading Int. J. Min. Reclam. Environ. (IF 1.917) Pub Date : 2018-06-18 William Fuentes, Melany Gil, Jose Duque
The stability of waste dumps of former open-pit mines must be guaranteed for its use on construction and other activities. In this work, a sandy waste dump subjected to a seismic event is carefully analysed. Its sudden settlement is simulated with a Boundary Value Problem (BVP) under dynamic conditions. The Intergranular Strain Anisotropy (ISA) constitutive model, able to simulate the behaviour of
