Study on Dynamic Characteristics of Hydraulic Combination Support in Coal Mine Roadway
To further explore the dynamic characteristics of the hydraulic combination support in coal mine tunnels,the hydraulic combination support used in conjunction with the EBZ260 tunneling machine in a coal mine comprehensive excavation working face was taken as the research object.Based on its specific parameters,a finite element model was built,and the dynamic characteristics of the hydraulic combination support were determined using simulation analysis methods to determine possible optimization strategies in the future.Meanwhile,further combined with on-site experiments,the effectiveness of the simulation analysis results was verified.This study will provide some reference and inspiration for the optimization design of hydraulic combination supports in the future.
