Abstract

The article is devoted to the development of a technology for the destruction of coal mass in the form of a coal-water suspension (CWS) by exposing it to extreme mechanochemical and electrophysical methods. This technology is a further development of the known method of mechanochemical processing of coals. The created test bench is described, including sections for the enrichment of fine coal and coal sludge by the oil granulation method, mechanochemical processing in a rotary-pulsation pump- cavitator (PPC) and a centrifugal cavitator (CC), and electropulse processing of CWS. A description of the improved design of the discharge chamber is given. The results obtained in the enrichment of fine coal and coal sludge by the oil granulation method, processing of the obtained coal-water and coal- water-oil suspensions (CWS) in PPC and CC, as well as electropulse processing (EI) are presented. The results of the experiments showed that the new design of the chamber for the electric pulse treatment of water- coal and water- coal-oil suspensions allows for the reliable destruction of the flowing mass in a continuous mode
