Abstract: With the rapid development of economy，mining enterprises have higher and higher re⁃ quirements for the comprehensive management level of engineering projects，especially cost management and resource optimization. Combined with a large mine，using analytic hierarchy process (AHP) and SPSSPRO analysis software，the weight comparison and data analysis of the eight factors that mainly affect cost management and resource optimization are carried out through expert subjective assignment. The results show that the weight value of the mesh parameters in the eight main influencing factors reaches more than 20%，which should be considered in the process of resource allocation optimization. The second is the charge structure and the detonation network，and the weight ratio of the two is about 15%. Therefore，in or⁃ der to obtain better blasting effect，more refined cost management is needed. Safety investment also has a greater impact on cost management，reaching about 30%. The research results can provide theoretical basis and parameter reference for how to efficiently allocate resources and refine management costs for related en⁃ gineering projects，so as to optimize the cost management of construction projects.
