Underground Dust Control Technology in Daliuta Mine

In order to solve the high dust density problem in the underground of Daliuta Coal Mine, a negative pressure inducted dust collector, dustfall agent of the fully- mechanized coal mining face, dust online monitoring and measuring and automatic spraying device, dust collected mesh of the fully- mechanized coal mining fac e, high pressure spraying device, HBKO 1 /600 mode dry dust control system and other means were applied to control the dust in the underground mine. The results sh owed that comprehensive dust collection rate of the fully- mechanized coal mining face and the driving face were 96. 71% and 97. 01 % individually and the undergroun d mine dust in Daliuta Coal Mine was effectively controlled.
