In order to realize the cantilever machine directional cutting and section cutting automatic control, and further improve the accuracy of automatic cutting forming control, the cantilever machine body posture automatic cutting technology and memory automatic cutting technology were proposed. By automatic testing of cantilever mining machine attitude, the cutting accuracy was improved, combined with computer control unit PCC, memory automatic cutting control system was designed, automation control precision of mining machine was improved. Underground industrial test results showed that the system was stable, with good control accuracy.
