| It is an important method for the rationality evaluation of roadway design that to prejudge the supporting effect before tunneling. and there has a positive significance for support design with a accurately prejudge of upporting effect in advance.There are many factors that impact tunnel support effect, such as Rock integrity, impact mining, coal size, surrounding rock stress,Should also be considered to be parameters used in bolting;The factors mentioned above mutual restraint, mutual association.Anchor for the Pingdingshan mining deep research supporting roadway, select a representative, detailed observations of rock pressure of 20 roadway, through the support index for judging the effectiveness studies to determine the strength bolting, rock strength, rock integrity, tunnel depth, impact of mining, roadway cross-section size of the roadway as a deep supporting effect evaluation index; rate according to experts, with the comparison matrix analysis method to determine the evaluation index weights. Fuzzy clustering analysis, give full consideration to supporting the effect of roadway impact on the effect of sample roadway classification,20 deep roadway divided into 4 categories, and identified the various types of cluster centers. Under specific conditions surrounding the D5-6-26071 Wind Tunnel excavation of its supporting effect to evaluate the use of the above findings, based on the evaluation results, supporting the original roadway under the program of supporting effect for the third category, support less effective; Therefore, this roadway support scheme adjustment. Supporting the new design, the effects of roadway anticipation, the result is a kind of anticipation, supporting effective. After a long time industrial test and pressure observation, tunnel deformation, roadway shrinkage was 12.4%, indicating that the effect of supporting the right to judge the results. Roadway support deep mining fuzzy comprehensive evaluation of the design of roadway has a certain significance.
