摘要

ZZ5200/11/18 powered support, made in China, is the first set of support with a full-face electro-hydraulic control system, operating with 4LS - 8 shearer and LX (3B) 1500 - 830 conveyor under an average seam height of 1.5 m, creating daily reacord of 7200 tons. This paper focuses on the characteristics and its designs, particularly in detials the hydraulic system. It also explains the technology of electro-hydraulic control or manual pilot control, of auto-setting to forward beam following front leg, of differential conveyor advance and rapid advance with a high flow rate system, which has played an active part in the roof control and rapid advance.
