Abstract: Abstract:In view of this situation that there are many types of potential roof pressure relief technical solutions, but under most conditions, qualitative methods are used to optimize among many alternatives,In this paper, the technical solutions selecting of the top-cutting roof pressure relief for 6105 working face of Yuan Bao Wan Coal Mine is taken as an example,by the method of hierarchical analysis which can achieve quantitative selection determining the top-cutting roof pressure relief measure.This method comprehensively analyzes the influence weight of each factor on the top-cutting pressure relief plan, avoiding the one-sided expansion of the influence weight of a certain factor, and displaying all the influence weights of each factor on the final plan in a quantitative form, the conclusion is more logical and scientific , having a strong guiding significance and reference value for the selection and optimization of the top-cutting pressure relief technology program with any other options which have many options to choose from.The results of the hierarchical analysis method show that the weight of the directional hydraulic fracturing top-cutting pressure relief scheme is higher than that of the blasting top-cutting pressure relief scheme aimed at the roof of 4# coal room pillar goaf overlying 6105 working face ,good results have also been achieved through practice.
