Having previously said it was weighing up a project to automate around 500 haul trucks across its Western Australia Iron Ore and Queensland Coal sites, BHP has shed more light on its autonomous haulage plans.

The company made the ambitious admission in May 2019. It has since said it will introduce autonomous haulage at the BHP Mitsuibishi Alliance Goonyella Riverside mine, in Queensland, in a staged project that will see up to 86 Komatsu trucks converted to autonomous mode.

In its half-year results released today, BHP said of the 500 haul trucks it previously spoke of 150 are currently “under feasibility or execution” and 350 are included in its “medium-term plans”. Two projects in the former category include the Eastern Ridge mine site, in the Pilbara, which the company is currently using as its proving ground for innovation, and the 4.5 Mt/y Daunia coal mine, in Queensland, which BHP opened in 2013 and has a fleet of 16 226-t payload trucks (including Cat 793Fs).

In terms of capital expenditure, these projects were expected to cost less than $800 million, including $250 million for sites in feasibility and execution and up to $550 million included in the medium-term plans, it said.
