Study on Fully-Mechanized Face Quick Withdrawal Suite of Hydraulic Support Design and Application

Abstract

This paper mainly analyzes suite of hydraulic support technical parameters and structure design applied to fully-mechanized faces withdrawal, according to coordinating with auxiliary roadway multi-channel crafts, which achieves fully mechanized support in the fully-mechanized face in Inner Mongolia and Shenmu. It provides automatic essential equipment for fully-mechanized face withdrawal. Using computer technology to study the suite of hydraulic support: Using designed analysis software optimizes and designs the support the structure parameter to achieve the optional performance and enhance stability, supporting performance and anti-twisting property. Experiment of prototype was produced to simulate the moving process exactly by virtual prototype technology and three-dimensional entity design software, optimizing the original project. Operating condition of supports in the underground mine was simulated for overall strength analysis with virtual prototype technology.
