Using of Shell Filtering Constructions for Concentrating Plant’s Coal Slurry Dewatering

The urgency of using mining waste is also emphasized by the environmental component: reducing the anthropogenic load on the region through the integrated development of mineral resources with an increase in the waste-free component of technological processes will undoubtedly improve the difficult environmental situation in Kuzbass. This will be reflected in the reduction of pollution of surface and groundwater, the atmosphere, the soil, the reduction of the land capacity of mining enterprises by reducing the area occupied by the treatment facilities. The study of the state of the issue of coal sludge dewatering showed that at present there is no unified technology of dewatering using geotextile materials (Geotube® etc.). With the general similarity of existing technologies, there were no uniform requirements for the preparation of raw materials, the site for work, the type, properties and parameters of the geotextile used, etc., which makes it difficult to apply this or that technology in industrial conditions and large-scale coal sludge. Thus, the purpose of this study is to select the most optimal geotextile material (in terms of price / quality ratio) and to develop a technological scheme for the dewatering of water-coal pulp formed in the radial thickener of the concentrating plant
