文摘The comprehensive evaluation of the schemes of coal mine design often involves some factors that are difficult to be expressed in quantity and these factors are often described qualitatively.Therefore, it is difficult for us to adopt uniformly concrete evaluation value to appraise each design plan.

Thus the quantitative model for evaluating design is set up by means of Fuzzy Mathematics and a concrete calculating example is given in this paper.\;The Fuzzy mathematical model proposed in this paper is good in adaptability and convenience.

After simple calculation, the quantitative result or comprehensive evaluation value that evaluates each design plan can be obtained,which provides a scientific basis for design personnel to choose the optimum scheme.
