Abstract: The measure evaluation of synergy degree of synergy mining methods has been an unsolved scientific problem in mining engineering.Mining methods were divided into the system structure of three-layer sub-system，and on this basis，the structure pattern graph of the synergy elements in the synergy mining method was drawn.A measure evaluation model of synergy degree of synergy mining methods was created by introducing the concept of synergy entropy.Based on the revised analytic hierarchy process and entropy weight method，the weighting method of each subsystem's synergy degree evaluation index was determined.According to the classification standard of the system synergy degree，the application process of the synergy entropy evaluation model is comprehensively illustrated with the example of pseudo-inclined pillar mining method for combined operation of electric rake and blasting force，and the statistical analysis of the synergy degree of the 19 synergy mining methods invented by Chinese scholars in the recent decade was made.The study results show that the structure pattern diagram of the synergy elements in the synergy mining method clearly shows the synergy relations among the elements and the structural relations among the technological links.The sample mining method is generally in the state of a basic synergy，in which stope mining， stope structure，ore removal and ore transport are in the states of good synergy，slightly unsynergy and highly synergy respectively.Among the 19 synergy mining methods，8 are in a basic synergy state，7 are in a good synergy state and 4 are in a highly synergy state.The above discussion results can provide reference for the evaluation of technical level of synergy mining methods.
