Research on explosion-proof technology for coal mine rescue robot

The paper introduced general situation of explosion-proof technology of coal mine rescue robot, and summarized the research status and application of explosion-proof technology of coal mine rescue robot at home and abroad, and pointed out some progress of explosion-proof technology for coal mine rescue robot, especially in explosion-proof motor, explosion-proof shell and power supply. However, there are still problems in explosion-proof material application technology, energy power technology, intrinsic safety control technology, fault diagnosis and fault-tolerant control technology, it needs to be constantly improved in the aspects of processing materials lightweight, power supply efficiency, intrinsic safety of explosion protection technology, intelligent control system, so as to ensure the explosion-proof technology of each component of coal mine rescue robot is more mature.
