Design and Simulation Analysis of Hydraulic Control System of Hydraulic Support Before High Mining in the Longitudinal Groove
In order to meet the requirements of automatic control of advance hydraulic support for large mining height along the channel,this paper combined with the action function requirements of advance hydraulic support during the support along the channel,carried out the overall design of support hydraulic control system,designed the control loop of double telescopic column,the push control loop and the side protection control loop respectively,and built the simulation analysis model of the three loops in turn.Then the AMESim hydraulic simulation software is used to carry out simulation analysis,and the displacement changes of each loop are analyzed according to the simulation results,and the loop is adjusted accordingly.The simulation results confirm that the design scheme of the hydraulic control system can realize the automatic support of the coal mine chute and ensure the safety of the coal mining process.
