[QUOTE="cml, post: 311616, member: 9449"] And in case some people interpret that as meaning that shotcreted and bolted roofs are safe ... I worked for Freeport in Papua a few years ago. They had a smaller mine under the open cut at Grasberg which they used for training. On May 14, 2013, 30 or so, mostly contractors, reported to the OH&S training room in that mine for their regular refresher, The room was a separate construction inside a large tunnel maybe 10 or 15m across and a similar height, all rock bolted, shotcreted etc, inspection regime in place. Class was just about to start, so the instructor walked out of the room to get the last couple of attendees inside, and without warning the roof collapsed and squashed 28 people to a pulp. I THINK there might have been four survivors in the room. [/QUOTE]
