Abstract: In order to solve the problem of the lack of the special and reliable equipment in the low and deformation roadway roof and side caving danger areas in coal mines, the selection requirements of the roadway treatment construction model and technology were proposed, and the WPZ-45/700LY remote control repair for coal mine was developed. We studied the key technologies of working mechanism, actuator, quick change device, hydraulic system and remote control system, analyzed the function and technical characteristics of each component of the repair machine, and conducted type tests on the ground. The cumulative ground repair footage was 50 m. The repair thickness was 0.3 m to 1.2 m, the remote control distance was 20 m, and the average lifting efficiency was about 2.8 m/h. The test showed that the remote control roadway repair machine has reasonable structural design, reliable hydraulic and electronic control systems, and high construction efficiency. It satisfies the technical requirements of construction equipment for roadway surrounding rock treatment.
