Kl9s must have been the brainchild of a nutcase because it was going into faulted ground. The geologists insisted that roof bolting was the way forward, we knew better. Anyway we had to have a go. At the pre start-up meetings it was explained that if we could roof bolt Kl9s Loader Gate Heading, we could roof bolt anywhere. What wasn't made clear was what to do when we found roof bolting a serious problem. They developed a new 38ton road header at Dosco and sent me to the factory for a week to have a look around it. It certainly was an awesome beast, laser controlled with CCTV monitors and two operators. It was loaded up and needed a police escort it was so huge, when they came to move it. Then we had to strip it down to little pieces, to get the thing underground. Hopefully we had got all the bits to reassemble the machine. When the time came to power it up, it fell to me to give life to my 38 ton beast. The management were on hand as were the Dosco bosses to see it at work. Ten minutes in the sweatbox was enough for them and in the year that it took us to cut the roadway we never saw them again. When it broke down, the best brains from the factory were often foxed and when I came on shift I would put my hands on the control covers and I would get a feeling where to look for the fault. Minutes later the head would be spinning and we would be away. Time after time it happened that way, it could have been broken down for two shifts and in ten minutes I would have her running again. I must just add that no one ever actually saw me putting my hands on the machine covers; if they had I would have been thought of as nuts. But then you had to be nuts to work on 19s. Roof bolting was a system where a 10 feet long hole was drilled into the roof using a Wombat machine. Epoxy resin capsules were then inserted into the hole, followed by a ten foot threaded rod the roof bolt, and the whole lot was spun mixing the resin. When the resin went off the roof was supported, in theory. Fine with good strata, it was just lethal here. Who were these superhuman guys who were going to cut and bolt a mile and a quarter? Jacko's super hard rock headers - that's who! |
