WOLLONGONG-headquartered Allied Mining Pty Ltd has formed a marketing and operations alliance with British group Kvaerner Cementation, under which it plans to pursue large-scale underground mine contracting and mine management projects.
Allied business development manager Gary Gibson said the company had completed more than 50 decline, drift and shaft sinking projects, and had moved successfully into the Queensland underground coal market with roadway development projects at Moranbah North, Oaky Creek and now Goonyella. “Allied is developing a highly regarded reputation as a safe underground mine development contractor,” said Gibson.
The Kvaerner Group, a leading international engineering and construction contractor, brought together several independent British mining contractors, including Davey Mining and Cementation, to form Kvaerner Cementation. The company spent last year researching worldwide business opportunities and one of its conclusions was that Australia’s underground coal sector had significant growth potential. Allied was identified as a suitable partner with which to enter the local market.
A joint statement by the two companies said: “The scope of projects envisaged includes contract mine management, development and operation of punch longwall mines, turnkey mine construction and development, major roadway development projects and, potentially, the introduction of new-technology development and mining systems.”
Meanwhile, Allied said it expected to finish roadway development for the Maywin project at Oaky Creek by September this year — six months ahead of schedule — after “handing over” longwall 16 gateroads to mine operator MIM five months ahead of schedule. Development is continuing on longwall 17 and 18 gateroads.
Gibson said development rates had averaged 23-24m per operating shift, or 300m a week, over the life of the Maywin project to date. At Moranbah North, where Allied recently completed 8.5km of the mine’s mains roadway system and panel entries for the next seven longwalls, the contractor averaged more than 240m a week. Development included 6m-high overcast cut-outs and 5m-high longwall drivehead excavations.
“In straight development operations, excluding drivehead and overcast excavations, advancing two three-entry sub-panels to form the six-entry mains, Allied achieved an average 40m per shift in the regular 3m-high roadways,” Gibson said.
More than 500 operating shifts were completed at Moranbah North without a lost time injury, though Allied’s goal of a zero-LTI project was denied by a single LTI incident as the project was wrapping up.
