Suspended dump truck body reduces environmental noise levels

摘要

The Moolarben Coal Operations joint venture, the operator of the Moolarben coal complex in the Hunter Valley region, in New South Wales, Australia, has invested about $3-million to buy six new Komatsu 830E haul dump trucks, with customised suspended dump bodies (SDBs) from SDB supplier Duratray. The investment was prompted by an environmental noise-reduction trial at the mine, last year, during which a SDB was used. In terms of the New South Wales Protection of the Environment Operations (PoEO) Act of 1997, which is enforced by the New South Wales Environment Protection Authority, some mines must establish a noise-management plan and be subject to the calibration and monitoring of acoustic sound levels.
