The CMS Continuous Loader Development And Application In Tunnelling

Continuous Mining Systems Limited have developed an efficient, high-capacity, in-line loading unit capable of handling shot rock in tunnel driveages at extraction rates up to 970 tonnes (1,000 tons) per hour. A smaller 408 tonnes (450 tons) per hour loader is also available These in-line loading units called "Osciloaders"® provide a continuous flow of material from the muck pile to an anciliary conveyance eliminating the cyclic or interrupted movement noramlly associated with gathering arm or bucket type loaders. The osillating lip fluidizes the material, reduces the penetration force required and facilitates and regulates the material flow onto the adjacent conveyor. The conveyor is wide and accommodates very large material with ease, transporting and elevating it to a height suitable for a waiting conveyance at the rear of the machine. The "Osciloader"® is currently being utilized for production mining by a major company in Sudbury, Ontario. Both truck and conveyor anciliary haulage are being utilized. The paper describes the development of the loader and how it may be applied in tunnelling applications.
