Abstract: This paper introduces a kind of coal dust inhibitor in the fully mechanized coal face mining process played in the process of dust removal effect, in 1327 fully mechanized coal mining face spray nozzle in proportion to adding coal dust inhibitor in the face of the drum cutting process through The coal dust can be controlled and suppressed by the internal and external spraying of the shearer. At the same time, the use of coal dust inhibitor in the process of water injection in the 1327 face, effectively improve the dust removal efficiency.
