To do quantitative evaluation of the geo-environmental carrying capacity and the pressureof coal mine through analytic hierarchy process, thus four factors such as geology geomorphology, }ov-er properties, hydrogeology and structural interface, will be chosen as the criterion layer of cariyingcapacity;land pressure, coal pressure and hydraulic pressure will be selected to be as the criterionlayer of pressure, arid the key factors included in the criterion layer will be regarded as evaluation in-dex system of indicator layer establishment.The indicator layer is assigned by using standard quattti-zation and rise semi-trapezoid distribution function;otherwise, the eigenvalue method will be usedto evaluate all the weight value of the indicator layer trough normalization processing.The carrying in-dex and pressure index are used to work out evaluation score by weighted computing layer by layerwhich aims at target layer.Taking Yunjialing mine for an example, the quantitative evaluation of thegeo-environmental carrying capacity and the pressure of coal mine are established by applying the e-valuation index system, the result turned out that the capacity is the higher capacity, the pressure isthe medium pressure, and the condition of the geo-environment of mine is good.
