Abstract: ZDY850LK type drilling rig is newly designed for deep loose and soft outburst seams. The drilling rig is the core of the remote control technology of underground tunnel drilling rig, three key technologies of drilling rod automatic handling, state test and remote-operation and control were specially studied. State test with operation and control system equipped with domestic drilling rig were developed. In the ground field test, it was validated that drilling rig can be handled automatically, condition parameters can be monitored, and drilling rig can be remote controlled.
