Study on improving efficiency of BWE system in Heidaigou Strip Mine

For improve the efficiency of the BWE (bucket wheel excavator) system in Heidaigou Strip Mine, a method of appraising the scheme of improving the efficiency of BWE system in Heidaigou Strip Mine was proposed. After studying main indexes of affecting the efficiency of the BWE system in Heidaigou Strip Mine, the AHP (analytic hierarchy process) model of improving the efficiency of the BWE system in Heidaigou Strip Mine was established. At last, the optimal scheme of improving the efficiency of the BWE system in Heidaigou Strip Mine was obtained. The study method and obtained conclusion were of significance for the mines with similar geological conditions.
