Research and Application of Fully Mechanized and Digitalized Unmanned Coal Mining Face in Thin Seam

In order to realize a digitalized unmanned mining of No.94702 fully mechanized coal mining face in thin seam of Xuecun Mine,according to the geological conditions of the coal mining face,the paper introduced the equipment selection process of the coal shearer,hydraulic powered supports and scraper conveyor.The location detection of the coal shearer,the automatic height adjustment of the memory cutting,the real time monitoring and control of the operation status,the automatic control of the hydraulic powered support electric and hydraulic control system and other functions were designed and realized.The results showed that with the rational coal mining method and the coal mining technique,the mining technology of the fully mechanized digitalized unmanned coal mining face was safety and reliable and could automatically realize the coal cutting,powered support moving forward,scraper conveyor and roof support and other production process.
