Canada remains at the forefront of continuous mining development and application. In particular the coal and potash mines are applying state-of-the-art equipment and the potash operators continue to refine automation of their machines. In hard rock at least three machines have been field tested in Canada cutting rocks up to a UCS of 300 MPa (43 500 psi): the HDRK/Wirth Continuous Mining Machine; the HDRK TM60 roadheader; and the joint venture Compact Underground Borer. There are others elswhere, such as the Robbins Mobile Miner in Australia. Key issues that will continue to be addressed include: improved machine reliability, better operating savings to offset high initial capital costs, increased efficiency of cutting and successful commercialization of the technologies involved. While the ultimate goal of 1 million tonnes of ore mined in one year from a single machine remains to be achieved, it appears to be within reach. The challenge will then be passed on to operating managers, engineers and planners to design applications of continuous mining technologies to optimize their benefits in both development and production operations, following the trial already blazed by their counterparts in soft rock.
