The Effects of Cutting Speed on Continuous Miner Cutting Performance

Abstract

In order to study the effects of cutting speed on a continuous miner cutting performance, set up the equations of Cantilever’s swing speed, draw graph of chips in different swing speed and rotate speed, analysis the effects of them on continuous miner cutting performance. In order to reduce the fluctuation of cutting speed and get large lump coal rate , reduce the rotate speed of drum and swing speed of cantilever as far as possible, and reduce the maximum swing angle.
