Brune interviewed by Casper Star-Tribune

Jürgen Brune, director of Edgar Experimental Mine Research and professor of practice at Colorado School of Mines, was recently interviewed by the Casper Star-Tribune for a story about safety issues at a southwest Wyoming coal mine where a miner recently died. 

From the story: 

Until the regulators’ reports are published, it is impossible to interpret what happened to Olivas, said Jürgen Brune, director of the Edgar Experimental Mine Research for the Colorado School of Mines, in an email.

“Face or [wall] rolls are unusual but this depends on the circumstances at each mine,” said Brune, an expert in longwall mining. “The type of failure or collapse experienced in this accident — by the limited information we have at this point — appears to have nothing to do with the normal longwall mining process.”
