Abstract: In order to study the equipment selection and matching of large mining height working face in closed distance seam, focusing on 2-512 working face of Sanjiaohe Mine, according to the geological conditions of 2-512 working face, the type selection calculation of shearer, scraper conveyor, gateway reprint machine, crusher and hydraulic support are implemented. The feasibility of the equipment selection and matching in working face is analyzed according to the calculation results. The calculation results show that shearer, scraper conveyor, consecutive stage machine, crusher and hydraulic support all satisfy the requirements of working face.
