YANCOAL Austar 300 Mains Surge Bin misting chambers
Design and installation of surge bin enclosure upgrades and misting chambers, verified by benchmark and post-install efficiency respirable dust testing.
Client / Location:
Austar Coal Mine (YANCOAL)
Near Cessnock, NSW (underground, 300 Mains panel surge bin)
Problem
-
Substantial dust cloud generated at the point where coal drops from the crusher to the underground bin, causing severe contamination and hazardous conditions.
-
Existing dust suppression system was not effective in mitigating the problem.
Solution
-
Enclosed the top of the surge bin and sizer using conveyor belt material to contain dust generated from the sizer.
-
Improved spray system on top of the sizer intake by installing an additional spray bar.
-
Installed two misting chambers to treat displaced air from surge bin filling using super-fine water mist.
-
Included water traps to reduce water carry-over and an air fan to ventilate the surge bin when idle to prevent methane accumulation.
