Modern longwall mining employs hydraulic powered supports at the face area. 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. Keywords:ZY3500/25/47 type root support shield; hydraulic support; structure design; strength analysis
