The deformation control of surrounding rocks is one of the key problems in deep mining, especially floor heave control. In view of coal mine disaster caused by roadway surrounding rock under complex geological conditions, the lack of special mechanical control technology and equipment, the construction characteristics of the surrounding rock maintenance technology is analyzed, the roadway multifunction repair machine and the floor anchor drill rig are developed and applied at Binchang Coalmine of shaanxi province. The field test results show that the set of technical equipment can effectively improve the mechanization and technology level of the coal mine roadway surrounding rock control. The study provides a reliable guarantee for the safe and efficient production, and has significance in the downsizing for efficiency in coalmines.
