Abstract: In order to solve the problem of lack of special and reliable equipment in the safe and efficient treatment construction of low deformation roadway in coal mine, in response to the construction goal of "mechanized replacement, automatic reduction, intelligent unmanned" put forward by the State Administration of work safety, wpz is developed by analyzing the construction characteristics and functional requirements of equipment and adopting the way of mutual communication between wireless receiver and wireless remote controller- 45 / 700ly coal mine remote control repair machine, and detailed analysis of the repair machine working device, hydraulic system, remote control system, crawler body composition and working principle. Taking the floor heave treatment construction of Guqiao Coal Mine as an example, the performance of the electric control system of the remote control repair machine is stable, reliable and fast response. At the same time, a set of operation technology is summarized, which is convenient for the replacement of the crushing hammer and the side dump bucket and the replacement of the anchor rod (cable) construction, so as to provide a reference for the development of similar coal mine roadway floor heave remote treatment construction technology and equipment.
