Реферат: eng: Industrial wastewaters disposal, in particular wastewaters appearing from the coal extraction and enrichment, is an important national economic task of preserving environment. At the same time, the applied wastewater disposal technologies must be ecologically safe and do not requires large financial expenses. This task is quite relevant for Kuzbass due to territory saturation of the coal, metallurgical and chemical industrial enterprises. The paper discusses a mathematical model of one of these technologies -the wastewater treatment in spent workings of closed and flooded coal mines. The proposed mathematical model allows studying the treatment processes occurring in the flooded mine workings, that using numerical experiments and taking into account the slurry water characteristics and changes of the incoming groundwater volume and of the injected wastewater volume. The process of suspended in mine waters coal and rock particles sedimentation and sediment compaction is given special attention in the model. Numerical experiments results, that allowing estimating the safe time mine act as a wastewater treatment plant, are presented. © Published under licence by IOP Publishing Ltd.
