Abstract: In order to solve problem of personnel safety caused by manual operation mode of roadheader in underground tunneling face at present, a remote video monitoring system of underground tunneling face was designed based on wireless network transmission, and components, function and application of the system on 12113 tunneling face in Yunjialing Coal Mine were introduced. The application showed that the system can collect, analyze, process and transmit video data in environment with coal dust and voilent vibration with satisfactory operation, and transmitting distance of wireless video signals achieves 40 m in tunnel as well as video monitoring distance is 500~20 000 m. The system realizes remote visual monitoring of roadheader.
