Unsuccessful Experience in Restructuring the Unique Factory Manufactoring Bricks From Waste Coal and Possible Ways for its Renovation
In the conditions of a necessary transition to wastes-free technologies and rational use of mineral resources the experience of operation of a unique in the world practice factory producingceramic bricks from 100% of waste coal by the method of semi-dry molding in Novokuznetsk (Russia) is described. The main factors for decrease in the production volumes and thefactory shutdown after more than 20 years of trouble-free operation are provided. The attempts to restructure the bricks manufacturing factory to production of coke and coal briquettesare considered. The examination results of chemical, mineralogical composition and technological properties of the current waste coal from different coal mines, located in the south ofKuzbass, at the Central Processing Plant “Abashevskaya” in Kemerovo region are given. The perspective scheme of the brick factory renovation including a complex processing of wastecoal, irrespective of the residual carbon content in the wastes, is offered.
