Application Analysis of Hydraulic Bracket Guard Plate Retraction and Release Monitoring System
Based on the comprehensive mining face hydraulic support gangplank in the support process due to the poor level of monitoring technology,monitoring is not in place gangplank collision deformation is serious,the support is not in place,the support effect is poor and other technical difficulties,Hanjiawa Coal Mine,through technical research,the 22403 working face ZF13000/25/38 hydraulic support gangplank of the roof coal discharge designed a set of gangplank receiving and releasing monitoring system,analyzed the monitoring system structure,working principle and function,and through the actual application results to see the gangplank receiving and releasing monitoring system,the monitoring system structure,working principle and function,and through the actual application results.The structure,working principle and function of the monitoring system are analyzed,and the actual application effect shows that the collision accident rate of the gangplank is reduced to 4％after the system is put into use,and the maintenance cost of the gangplank is reduced by 475,000 yuan/a,which has achieved significant application effect.
