Improved mining machine and method of control

摘要

A system for controlling a mining machine comprises a co-ordinate position determining device, at least one co-ordinate reference point and a processor. The processor is 5 connected to receive data relating to an absolute co-ordinate position determined by the position determining device and the at least one reference point. Data relating to the determined absolute co-ordinate position is corrected by reference to the at least one reference point. The processor is connected to generate further signals to activate a mining machine actuator, rail actuator and/or extraction device actuator based on the corrected 0 absolute co-ordinate position, the processor operating with at least one of the actuators such that the extraction device will cut, or attempt to cut to an intended cut profile.
