The support not only holds up the roof , pushes the face chain conveyor , and advances itself , but also provides a safe environment for all associated mining activities . Its successful selection and application are the prerequisite for successful longwall mining .Therefore the coal mining of comprehensive mechanization is the way that must be taken to increase significantly coal output and enhance the economic efficiency. In order to meet the needs which grows day by day to the coal, we must largely produce comprehensive mechanization mining coal equipment, rapidly increase the comprehensive mechanization mining coal working surface. The followings are introduced in this paper: the develop history and latest dynamic state of the support equipments at domestic and international; the develop history and develop direction of the hydraulic support; components, functions, and types of the hydraulic support; the hydraulic control system of the hydraulic support; the normal design process of the hydraulic support; the hydraulic support’s operation, maintenance, fault analysis and processing and so on. In the design process of ZY3500/25/47 type root support shield, this paper will focus on the analysis and design of canopy, caving shield, base and hydraulic legs, as well as the connection method of leg with base and canopy. The important structure, such as canopy, base, hydraulic legs and so on, are analyzed. According to its failures, affecting factors and basic considerations, the design method of the strength and stiffness of the important structure is introduced. Finally, this paper describes using, maintenance, development tendency of hydraulic support. Keywords：ZY3500/25/47 type root support shield; hydraulic support; structure design; strength analysis
