ENERGY-SAVING MINING COMPLEX Russian patent published in 1997 - IPC

FIELD: mining industry. SUBSTANCE: mechanized mining complex is intended not only for excavation of solid fuel but also its processing for producing high quality fuel of certain class and also utilization of coal fines directly at place of mining without loss in reloading and it can be used for development of thin seams, at local industry quarries where erection of stationary benefication and briquette producing plants is not feasible. In mining coal seam, excavated coal from working member of machine is carried by delivery conveyor to separation and sorting unit. Then sorted coal of certain class is directed by conveyor to packing machine for packing in combustible bags. Coal of other classes is discharged by turning cantilever conveyor to containers carried by transport facilities. Coal fines after separation and sorting is carried to briquetting operation. Thus produced high quality solid fuel in bags and briquettes is loaded to containers which by turning crane are transferred to transport vehicles or placed on ground. Turning crane is also used for unloading of consumable materials (bags, binding matter). Altogether coal can also be dispatched. EFFECT: high efficiency. 1 cl, 3 dwg
