    Abstract: A highwall mining equipment extraction and retrieval apparatus and method is disclosed. It includes remotely operable hydraulic cylinders fixed to the mining head and stabilizing arms which brace the mining platform against the face of a mine. Wire ropes extend from hydraulic cylinders, through channels in the pushbeams, through lockable blocks fixed to the mining platform, and onto storage spools. The hydraulic cylinders operate from an extended to a retracted position. When a mine collapse occurs, an operator can remotely actuate the lockable blocks and the hydraulic cylinders, thereby locking the wire rope to the platform and pulling the mining head and pushbeams towards the platform. If the obstruction remains, the locking blocks can be unlocked, the hydraulic cylinders extended from the retracted position, the excess wire rope pulled from the mine, and the process can then be repeated until the equipment is free from the obstruction.
