Preparation of Coal Mines to Localization of Water Leakage

The threat water breakthrough into coal mines has been assessed. The operation of drainage system elements in normal and emergency modes has been examined. The data about the sources of water flow and the amount of the maximum and steady inflows of water has been collected. The prospects of the accident development, depending on the value of entering the production stream have been studied. Degradation drainage system increases the risk of complications of accidents and threatens the lives of miners.
