Abstract

A method and apparatus for continuously transporting mined material for a determined distance from a continuous mining machine in a mine having a roof and a floor to a permanently installed extendable length conveyor in a mine. The method is accomplished by installing an overhead rail supported conveyor along and above the fixed and extendable length conveyor. The overhead rail supported conveyor has at least a length equal to the determined distance and in addition the overhead rail supported conveyor includes a pivoted feed. A self-propelled tramming conveyor is installed having a length at least equal to the determined distance with its discharge cooperating with the pivoted feed of the overhead rail supported conveyor and its feed adapted to receive the material mined by a continuous mining machine. When the conveyors have travelled the determined distance, the overhead rail supported conveyor has its feed pivoted upwards flush with the remaining portion of the conveyor and rolled back over the fixed conveyor. The fixed conveyor is extended the length of a new determined distance. The overhead rail supported conveyor is then moved again over the fixed conveyor with its feed repivoted downwards in position to receive material from the tramming conveyor. The tramming conveyor is then moved back into position for a new mining sequence.
