A continuous mining machine for excavating a longitudinal shaft or tunnel underneath the surface of the earth. The machine has a working platform that mounted on the transport mechanism, and a cutter platform is mounted to the working platform. The cutter platform pivots on the working platform, such that the cutter platform moves in a reciprocating, arcuate movement around the forward end of the working platform. A cutter member mounted to the cutter platform through a cutter mounting module moves in a reciprocating, linear motion on the cutter platform. The cutter member is capable of performing a forward, backward and circular cutting pattern. The machine is capable of roof bolting operations simultaneous with the cutting operation. The machine is mounted to the transport mechanism to pivot about a vertical axis through the transport mechanism. A lift is provided for lifting the working platform upwardly from the floor of the excavation to support the entire mining machine on the life and suspend the transport mechanism above the floor. The transport mechanism can then be turned and the machine lowered to the floor of the excavation to change the direction of advance of the mining machine.
