深部A组煤层底板灰岩含水层疏放性评价

摘要

In that paper, based on the analysis of geological and hydrogeological conditions , the - 660m level of C3 Ⅰlimestone aquifer hydrogeological conceptual model and mathematical model is established; by using numerical methods, the hydrogeological model is identified and verified, the aquifer hydrogeologic parameters is obtained; through the water inrush codfficient methods,water inrush danger of the floor water invasion is evaluated, and dis- charge of the krast water was evaluated by using established model.%该文在分析研究区地质及水文地质条件基础上，建立了-660m水平C3Ⅰ组灰岩含水层水文地质概念模型和数学模型；利用数值计算方法，对水文地质模型进行了识别和验证，得出含水层水文地质参数；采用突水系数法对底板突水危险性进行评价，并利用所建模型进行灰岩水疏放性评价。
