The reform of the system concerns the reinforcement of the links among the criminal technology organs, the positive construction of market system and the rational resource distribution.
This article has made an photoelastic study of the influences of geological structure on the stress distribution of wall rocks and an estimate of the rational range of reinforcement.

The results show that the homogeneous stress and strain profiles can be obtained by adjusting the distribution of hole for a given number of holes on the surface of the reinforcement.
