Abstract: Puzzles mine roadway floor heave governance seriously affect the safety of mining operations mine for artificial as a low bottom efficiency, labor-intensive and so the status quo, developed WPZ-55 / 50L roadway repair machine, with a high degree of mechanization, construction and high efficiency, low labor intensity, and grew up in a Buddhist temple in Shaanxi Coal Bin conducted a field test and promote the use of good results. And according to the characteristics of the construction site, summed up a set repair machine since the end of the construction process for the standardization of the construction machine repair has laid a good foundation.
