为了避免煤矿深部煤层开采突水事故发生，探索重复采动工作面开采过程中底板潜在导水通道形成规律，以平顶山天安煤业股份有限公司十矿己17-33200工作面为工程背景，在两巷采取“梅花”式布置20个检波器，组成全包围式监测阵列，对工作面进行连续、实时、动态监测，利用微震技术对下层煤重复开采过程中上覆岩层塑性区破坏变化规律及底板深部微震事件进行分析，并结合理论计算探究潜在导水通道的形成规律。

 In order to avoid the occurrence of water outburst accidents in deep coal seam mining, the formation law of potential water conducting channels in the floor during the mining process of repeated mining face was explored. Taking No.Ji 17-33200 Face of No.10 Mine of Pingdingshan Tian 'an Coal Industry Co., Ltd. as the engineering background, 20 geophones were arranged in the ' Meihua ' type in the two roadways to form a fully enclosed monitoring array to continuously, real-time and dynamically monitor the working face. The microseism technology was used to analyze the failure law of the plastic zone of the overlying strata and the deep microseism events of the floor during the repeated mining of the lower coal, and the formation law of the potential water conducting channel was explored in combination with the theoretical calculation.
