研究采矿活动对厚松散含水层扰动影响是一项很有现实意义的工作，可以为厚松散含水层下隐伏矿井的安全开采提供科学保障依据。以河南永城煤田某矿13021工作面为研究原型，通过相关地质条件建立工程地质模型，借助有限元分析方法，对采动过程中底部含水层特定监测位置的应力路径及体变特征进行了相关研究，分析认为各点的应力状态及体积应变均受。工作面推进距离的控制，一定程度上解释了采动水压力的变化机制。

Study of disturbing effects of mining activity to thick aqueous soil layer could provided scientific guarantee basis for safety mining of hidden mine below thick aqueous soil layer and had practical significance. Took 13021 working face of a coal mine at Yongeheng in Henan province as the study model, engineering geological model established through relative geological conditions and by means of finite element method, relative study was done on stress path and strength characteristics of specific monitoring position at bottom aquifer in mining process, the result indicated stress state and volumetric strain of each points were both controlled by working face advancing distance, which explained changing mechanism of mining water pressure at a certain degree.
