A mine of structural and civil engineering and support structures for raisebore shafts

Our work in the expanding and often far flung mining sector around rural and regional Australia, and abroad, involves both general and specialist projects that include:

  • design of concrete collars and support steelwork for raisebored airshafts and the like and
  • design of general structures, projects and infrastructure for mining companies

Raisebore mining of shafts consists of:

  • constructing a concrete collar on the ground surface or at the top of the shaft
  • drilling a pilot hole from the surface to intersect an underground drive
  • taking a reaming (mining) head into the mine drive and attaching it to the end of the drill rod used for the pilot hole. The reaming head, powered by a unit on the surface, is rotated and pulled back up to the surface, creating a shaft, with the spoil falling into the drive below for removal by loader

Shafts, either vertical or inclined, may be up to 6m in diameter and up to 1,000m deep.

While the raiseboring is undertaken by specialist mining companies, we are engaged to design the concrete surface footings and support steelwork.

General Mining Projects

General mining projects in the form of civil and structural engineering design for mining companies span:

  • roadway and hardstand areas
  • conveyor supports
  • crusher support frames
  • general steelwork assessments and design
  • equipment footing design
  • work stage design
  • raisebore collar designs
  • specialised design projects

Specialised Design Projects

Specialised design projects cover areas such as the refurbishment of ore bins, ore pass chutes and conveyor support systems, as well as general services support.  They are undertaken, on behalf of clients, on an as needs basis.
