Abstract: In view of requirement of safe and high efficient mining for protection layer of thin seam of a coal mine, the paper proposed a design scheme of unmanned coal face mining for upper protection layer of No.2 thin seam of the coal mine. According to actual situation of 22201 first coal face of the No.2 thin seam, it gave matching equipment selection of shearer, hydraulic support and scraper conveyor of the 22201 unmanned coal face, and introduced network structure and mining process of automatic control system of the 22201 unmanned coal face in details. The industrial test result shows that the scheme can automatically finish production process of coal cutting, support advancing, scraper conveyor pushing and roof supporting, and realizes automatic mining for thin seam coal face.
