Abstract (en)

Method for obtaining aggregate of post-mining gangue obtained from the process of classification and concentration of coal and from underground preparatory works and coal seam works, characterized in that the gangue is driven by belt conveyors to the hopper (3), from where it is redirected through a magnetic separator (4) eliminating metal contamination, to the selective impact crusher (5) of first degree comminution, wherein the product obtained from this crusher is initially screened through a double-deck vibrating screen (6), wherein the under-screen product is stored as material for backfilling of mining workings, and the over-screen product is subjected to a subsequent process of crushing in an impact selective crusher of second stage comminution (7) and then the crushing products are targeted to triple-deck vibrating screen (8) to undergo a process of classification. The system of devices for obtaining aggregate of post-mining gangue contains consecutively arranged devices: hopper (3), magnetic separator (4), selective impact crusher (5) of first-degree comminution, double-deck vibrating screen (6), selective impact crusher of second-degree comminution (7), and triple-deck vibrating screen (8), wherein the devices included in the system are joint by a system of central dedusting (9), which captures dust generated during operation of crushers (5) and (7) and vibrating screens (6) and (8).
