Abstract: Scientized mining is the objective requirements of human beings for coal mining，and the advanced stage for human obtaining coal resources from the nature．The scientized mining has been related to the human social and ecological environment safe and harmonious development，and also healthy and sustainable development．Based on the connotation of scientized mining，guarantee measures and objective analysis of the mining conditions，confirmed the scientific evaluation system which composed of by 5 first-class indexes，33 second-class indexes and 64 third-class indexes．By the use of method with experts-input-parameter，the standard value method，switching function method, sub-function method，qualitative value method，and other means to achieve the evaluation index of the dimensionless processing．Combined with industry characteristics，respectively，in the process of weight determination and quantification，give full play to the role of evaluation expert，and by optimizing subjective weighting of experts participation together，realizes the target weights of evaluation system in dynamic．Using scientized mining coefficient (ScMC) to quantify expression the scientized mining level of the evaluated mine．

Key words: scientized mining, scientized mining coefficient, dynamic weight, quantitative evaluation
