Automatic Matching Equipment and Technology of Fully Coal Mining Face in Thin Seam

In order to improve the resource mining rate of the thin seam and the mining efficiency,based on the practices on the mining in the thin seam coal mining face,the theoretical analysis and the industrial trial were applied to study the mining equipment selection for the automatic coal mining face in thin seam.The hydraulic powered support,coal shearer and scrape conveyer suitable for the fully mechanized mining in thin seam were researched and manufactured.With the automatic platform of the coal mining face established with the video monitoring and control functions,the automatic level of the coal mining face was improved.A industrial trial was conducted in Huangsha Mine,an automatic mining in a thin seam with a thickness of 0.75 m was realized.The month production of the trial face was 36,700 t.The coal mining rate of the mine was increased by 4% and the mine service life was ecteded by five years.
