Description

Authors have presented the theoretical assumptions for a modified and simplified method of forecasting the inflow of water to underground mine excavations using open-source GIS software. The proposed solution is based on the determination of the value of mine-water inflow index (qA) that represents a unit of mining excavations area.
The proposed version of the method includes the variation of inflows to mining excavations (zonality of inflows) and depends on the volume of inflows from the time that has elapsed since the excavations were made (determination of intervals of characteristic values of inflows within the spatial zones).
The paper compares the values of the mine-water inflow index (qA) that were applied to conduct inflow forecasts to values determined on the basis of actual inflows to mining excavations. Values of mine-water inflow index applied in forecasting based on multiannual verified measurements of inflows to excavations. Data analysis and forecasting were performed for a selected area of the copper ore mine within the boundaries of the Fore-Sudetic Monocline.
