| Abstract: | According to disease mechanism of roadway, the tunnel design and technology is optimized, with the replacement of small section joist steel supporting with large section u--steel supporting. This optimization has brought about real increase in tunneling efficiency, thus solved the problem of tunneling in the unstable coal seam. |
