Aug 15, 2018· Those samples were compared with similar ones taken from the conventional mining equipment and identical mining fields. Significant advantages emerged when working with the surface miner, which produced 14% fewer fines at grain sizes of less than 2 mm compared to the conventional mining .
This paper provides information on the severity of dust sources in conventional coal mining operations, and presents guidelines on the use and implementation of dust control procedures to reduce respirable dust levels.
In the mine, the coal is extracted from the seam by conventional mining, or by continuous mining, or by longwall mining, or by shortwall mining, or by room and pillar mining. Conventional mining (also called cyclic mining) involves a sequence of operations in the order: (1) supporting the roof, (2) cutting, (3) drilling, (4) blasting, (5) coal ...
