Remote-control underground gas extraction drilling machine

The invention discloses a remote-control underground gas extraction drilling machine. The drilling machine comprises a host machine of the drilling machine and an electric control system, wherein the electric control system is used for controlling the operation of the host machine of the drilling machine and comprises a main control station, a remote control station and a communication device; and the communication device is used for transferring information between the remote control station and the main control station. In the remote-control underground gas extraction drilling machine provided by the invention, the operation of the host machine of the drilling machine is controlled by the remote control station arranged on the ground, so unmanned operation of the host machine of the drilling machine is realized, an operator does not need to enter a site of a severe environment and the life safety of the operator is guaranteed; at the same time, the operation process of the host machine of the remote-control drilling machine is fully automatic operation, so the operation efficiency is high; and signals acquired by a video acquisition device and a sensor which are arranged on the host machine of the drilling machine can help the operator in the remote control station to know the operation condition of the host machine of the drilling machine at any time, so the reliable operation of the host machine of the drilling machine can be guaranteed.
