In this study, a three-dimensional finite difference numerical model of the Jinfeng Gold Mine, including surface topography, ore body, shafts, and main faults, was built to estimate shaft stability deformation induced by underground mining transferred from open-pit mining. Satellite monitoring data displacement at several points used calibrate model. The sequence excavation filling in simulatio...

In order to carry out an open pit mining operation, planners must periodically prepare what is known as strategic mine plan. This is a tentative production schedule for the remaining life of the mine that defines which area of a mining reserve will be extracted, in what years this extraction will take place, which resources will be used for the extraction, and how the extracted material will be...

In this study, a hybrid intelligent model has been designed to predict groundwater inflow to a mine pit during its advance. Novel hybrid method coupling artificial neural network (ANN) with genetic algorithm (GA) called ANN-GA, was utilised. Ratios of pit depth to aquifer thickness, pit bottom radius to its top radius, inverse of pit advance time and the hydraulic head (HH) in the observation w...

In this paper, an infrastructure for monitoring remote equipment and solving some of the logistic challenges of operating satellite surface mines is presented. This infrastructure includes strategies for communicating timely and accurate information amongst operators, planners and supervisors, using off-the-shelf network protocols. Advanced data visualization techniques are implemented, so user...

This paper proposes a newmathematical framework for the open pit mine planning problem, based on continuous functional analysis. The main challenge for engineers is to determine a sequence of nested profiles maximizing the net present value of the mining operation. The traditional models for this problem have been constructed by using binary decision variables, giving rise to large-scale combin...
