研究本矿井煤层底板岩体采动影响特征是研究煤层底板突水的前提条件，确定开采后底板破坏带或底板裂隙带尤为重要，为回采前采取相应的防治水措施提供依据。本文通过采用FLAC3D数值分析方法来模拟研究郭村井田工作面回采过程中底板应力场、变形破坏特征及其影响因素，更切合实际地对郭村井田二1煤层采动过程中底板破坏进行研究，并发现其破坏规律。

Study on the influence of mining feature is the premise condition on water inrush from coal floor of the coal seam floor rock after mining, to determine the breaking zone or floor crack zone is particularly important, and it will provide the basis for water prevention measures before mining. This paper uses FLAC3D method to conduct numerical simulation research on bottom stress field, deformation and failure characteristics and influencing factors in the mining process of Guocun field to more practically study the coal seam floor in Guocun field 2-1 coal mining process and find the failure rule.
