Method for setting up an electrical transportation infrastructure of a mine, method of mining in a mine, and a planning system for a mine

PendingUS20260119736A1Geometric CADForecastingTransportation infrastructureElectric transport
A method for setting up an electrical transportation infrastructure in a mine includes receiving mining data for different time periods of a mining interval. The data identifies expected source locations where material is extracted and destination locations where it is delivered. Using this data, a time-dependent 3D network of the mine is determined for each period, either as separate networks of paths connecting the source and destination locations or as a single network covering all periods. Based on this network, a planned placement of the electrical transportation infrastructure is numerically determined to at least approximately minimize the expected total costs of the mine over the mining interval. These costs include estimated environmental costs from transporting material between source and destination locations, subject to mining constraints. Finally, the electrical transportation infrastructure is initialized in the mine according to the planned placement.
