The CAN was first introduced to underground coal mines in Australia in the early 1990s by Burrell Mining. In October 2024 Burrell Mining sold to an Australian Small Business owner and was renamed Burrell Services Australia Pty Ltd. Burrell Services is located in Mackay, North Queensland.
The CAN is a yieldable secondary roof support cylinder. The CAN system is engineered to combine the superior load characteristics of concrete and steel.
The uniformly consistent core blend ensures each CAN delivers the same high load carrying performance.
The CAN cylinders with either a Steel or Fiberglass shell can be manufactured to the Underground Mines height requirements. Steel Cans are made in 760mm or 915mm diameter, fiberglass is generally 900mm diameter.
Burrell FRC Blocks are manufactured with controlled blending, mixing and forming techniques to assure a uniform dispersion of nylon fibers throughout each block.
Quality controlled batching, mixing and pouring, designed to meet or exceed Bureau of Mines standards and testing by independent laboratories assure constant strength control.
Cribbing, constructed with the superior strength and stiffness of FRC Blocks are better able to take slack in the mine roof, greatly reducing the roof-to-floor closure, without failure.
