For the longwall system at the Yalevskogo mine, SUEK combined roof supports from other longwall faces. In total three different types of roof supports were combined – with varying closed and extended heights. And since the longwall system at Yalevskogo mine is fully automated, all three types of roof supports were upgraded with a PMC-R roof support control unit.
Today, more shearers in the U.S. are running with Joy's Advanced Shearer Automation (ASA) and these longwall operators are starting to see the benefits with consistent extraction heights and floor profiles. "The immediate, primary goal with remote management is to keep the operators out of harm's way," Franklin said.
