Development and substantiation of technological facility of coal mining and processing

A process design is developed and substantiated for a technological facility composed of a coal mine (open pit mine) and moduli meant for coal preparation, coal–water slurry fuel production, power generation and manufacture of paste backfill. According to the elaborated concept, coal from underground or surface mines goes to wet processing in the coal preparation module which produces coal concentrate, rock refuse (0–200 mm) and coal slurry (0–0.5 (3.0) mm). Coal slurry is forwarded to the module of production of coal–water slurry fuel which is fed in the boilers of the power generation module which generates electrical and (or) heat energy for self-consumption and external supplies. Rock refuse of coal preparation and ash after combustion of coal–water slurry fuel at the power generation plant are sent to the module of manufacture of paste backfill. The produced paste backfill with the required rheological and textural characteristics is transported using special pumps and pipelines to mined-out voids in underground or surface mines. The ecological and economic efficiency of the technological facility results from the use of the backfill made of the rock refuse and ash waste to be placed in mined-out voids, and from the use of the own and cheap electrical energy produced at the power generation module.

Keywords: technological facility, coal mining and processing, coal–water slurry fuel, coal preparation refuse, ash, power generation module, paste backfill.
