Abstract：Taking the 12402 super-high fully mechanized working face of Shangwan Coal Mine as the background,aiming at the problem that the low operation rate seriously restricts the high production and high efficiency mining,through the analysis of the correlation diagram,it was concluded that the maintenance,the project quality control,and the organization and coordination were not in place,which were the three factors restricting the operation rate.It was also confirmed that the maintenance and engineering quality control are the crucial factors.And to deal with that,it was proposed to enhance mine pressure prediction,predict the strike of coal seam,improve equipment maintenance standards,develop key maintenance projects.After the implementation of the scheme,the operation rate was significantly improved,bringing huge economic benefits for the enterprise.
