Abstract
The technique of hydro-geological forecasts of conditions of flooding of coal mines is considered. The urgency of this question is determined by mass flooding of mines in the main coal-mining areas, at which serious problems arise connected with ensuring of ecological and industrial safety of liquidation works. Hydrodynamic processes, developing at flooding of mines, are very specific, that defines necessity of additional analysis and perfection of existing numerical geofiltration models. Among methodological techniques, used in prognostic assessments of mine flooding conditions, special attention is given to methodology of solving so called test tasks, reflecting typical conditions of mine flooding. As an example, the results of numerical modeling, obtained for three tests, are offered. Recommendations on the application of numerical models under different hydrogeological conditions are developed.
