3、oal, the technician do a lot of work, accumulate much information and get abundant experiences from supporting theory and practice. Recently pin timbering has been extensive used because the bo

4、lting of coal road has mellowed, however the problem of difficult tunnel reinforcement haven’t been solved properly, for example, wide span tunnel, heavy section. All in all, whether can we wor

5、k out the problem is a critical issue for coal exploitation and safety in production. By means of theoretical analysis and field practice, bolt supporting of wide span tunnel is studied wholl

6、y and systematically. This paper summarizes the mechanism of destabilization in bolting roadway and supporting theory. Based on generalizing the method which the design of bolt supporting, this

7、thesis study the parameter designing method which about bolt supporting in big section of rectangle tunnel. Through using the way that rectangle roadway equivalent ellipse, to determine the floo

8、r of tunnel’s plastic zone. On the base of establishing mechanical mode, the paper analysis the wall of tunnel’s plastic width. It is based on elastic- plasticity theory of limiting equilibrium

9、. The parameters of bolt supporting are designed after defining the plastic zone. We carried out the practical study on the ground of large span coal that the second Huangling coal. The bolt
