Shearer self-adaptive adjusting high has an important effect on coal mining automation and high efficiency, this paper will pres-sure compensation valve used in coal mining machine hydraulic height adjusting system, cylinder flow is not affected by load but its open-ing only depends on the valve port, the method solves the problem caused by change of load flow uncertainty the problem of the drum, the precision of adaptive control of high is more higher than before.
