Study and Practice on Automatic Mining Technology Applied to Fully- Mechanized Coal Mining Face in Thin- Medium Thick Seam

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 con trol system, powered support electrohydraulic control system, coal mining face conveying control system, three machine control system, pump station control system an d 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 gatew ay and an automatic production of the coal mining process was realized. The site application results in Huangling No. 1 Mine showed that, after using this technology, t he average output per day was 6 400 t, and the efficiency was increased in the fully- mechanized coal mining face.
