Olympic Dam 64L Dump Station Rail Beams Replacement
WGA assisted BHP to develop a procedure for removal and reinstatement of two rail beams with depth 2500mm and 1500mm. The beams provide support for the wagons tipping the ore in the crusher at level 64L. WGA carried out the structural design for the new reinforced concrete in which the two new beams will be embedded and the wear plates liner protecting the concrete from abrasion. Laser scans of the mine surface were used for 3D modelling of the lifting and the manouevring of the new beams in their final position within the mine’s highly restrictive space.
