在煤矿工作面回采过程中，背向斜构造的出现极易影响工作面安全。基于赵固一矿16091工作面微震监测数据，对通过背斜前期、中期、后期三阶段时空、能量动态演化特征进行总结。研究表明，上分层回采遇背斜构造时，微震事件频次呈现W型变化趋势；顶底板比例变化明显，由推采至背斜轴部中间位置之后，顶板事件占比大；通过背斜过程中，底板事件分布呈“单峰偏态”分布向“单支双曲线”型分布转化；通过背斜前期底板事件密度大，底板扰动深度较其他阶段要深，能量指数高，对应的涌水量高，呈现“前段危险”现象，结合微震、水位观测等做好预警工作，以保障工作面的回采安全。

 In the mining process of coal mine working face, the emergence of anticline and syncline structure can easily affect the safety of working face. Based on the microseism monitoring data of No.16091 Face in Zhaogu No.1 Coal Mine, the spatial-temporal and energy dynamic evolution characteristics of the three stages of the early, middle and late stages of the anticline were summarized. The research showed that the frequency of microseism events presented a W-shaped trend when the upper layer mining met the anticline structure. The proportion of roof and floor changes obviously. After the mining was pushed to the middle position of the anticline axis, the proportion of roof events was large. In the process of anticline passing through, the distribution of floor events was transformed from ' single peak skewness ' distribution to ' single branch hyperbolic ' distribution ; the density of floor events was large in the early stage of passing through anticline, the depth of floor disturbance was deeper than that in other stages, the energy index was high, the corresponding water inflow was high, and the phenomenon of ' front section danger ' was presented. Combined with microseism and water level observation, forewarning work was done to ensure the safety of mining face.
