Abstract
In a mining scheme, a mobile continuous haulage system follows a miner and transports material onto a floor mounted beltway. The beltway supports a roadway on which the haulage system is carried. The roadway has wheels captured in outboard rails on the beltway and lift cylinders on the roadway when lowered, raise the beltway off the floor so that the beltway can be advanced for a belt move to facilitate adding additional belt sections.
