Study and Practice on Automatic Mining Technology Applied to Fully-Mechanized Coal Mining Face in Thin-Medium Thick Seam
XU Jian-jun
Abstract：In order to improve a coal recovery rate of coal resources from a thin-medium thick seam,taking an unstable thin-medium thickseam in Huangling No.1 Mine as a study object,a matched technology plan of a high automatic fully-mechanized coal mining face was provided.With an organic integration of coal shearer control system,powered support electrohydraulic control system,coal mining face con-veying control system,three machine control system,pump station control system and power supply system,a centralized equipment control of the fully-mechanized coal mining face was realized by the monitoring and control center in the mining gateway and an automatic produc-tion of the coal mining process was realized.The site application results in Huangling No.1 Mine showed that,after using this technology, the average output per day was 6 400 t,and the efficiency was increased in the fully-mechanized coal mining face.
