Methodical and Applied Aspects of Hydrodynamic Modeling of Options of Mining Operation Curtailment

Abstract:

The physicomathematical conjugation of filtration models of a flooded and an adjacent mine is carried out with a justification of methodological principles of analysis and prediction of a technogenic mode of groundwater in conditions of operation and flooding of a mine field. The identity of models and real objects is established as a result of solving a series of inverse problems and is confirmed by a water balance discrepancy of 0.003%, the convergence of water inflows in separate layers with a deviation of 5 – 12.5% and the coincidence of groundwater surface levels on models and data of a mode network. According to results of predictive solutions, it is established that dynamics of flooding of a rock massif within old stopes are more intensive than the restoration of a level of groundwater in a mine shaft. The options of technical solutions for curtailment of mining operations are justified, the ecological risks and costs of which can be optimized by constructing a water intake of technical (or drinking) water in the productive stratum of riverbed sandstones, as well as equipment for geocirculation heat supply systems using the capacitive resource of a flooded mine field.
