中文摘要：

为解决白庙矿二1煤层底板防治水问题，分析了底板含水层赋水特征和矿井历年突水情况，基于渗流转换机理预算了主要断层突水量．结果表明，太原组下部石灰岩含水层和寒武系石灰岩含水层是底板突水的重要水源，云盖山正断层和下白峪正断层是潜在的底板突水通道，一旦发生底板突水，断层突水量将达1000m3／h以上．提出了以疏水降压为主、预注浆堵水为辅的底板综合防治水措施，寒武系石灰岩含水层的疏放效果证明了此措施是可行的．

英文摘要：

To solve the water control problem of Ⅱ1 coal seam floor in Baimiao mine, the water enrichment characteristics of coal seam floor and the water inrush conditions in past years are analyzed. Based on the flow conversion mechanism, the water inrush quantities of main faults are budguted. The results show that the lower limestone aquifer of Taiyuan group and the Cambrian limestone aquifer are the important water inrush sources. And the Yungaishan normal fault and the Xiabaiyu one are the potential water inrush channel of floor. The fault water inrush quantity will be over 1000 m3/h if the floor water inrush happened. Lastly, the integrated water control measures are proposed, including the main method of the dewatering and the subsidiary role of pre - grouting. And its feasibility is proved by the practical dewatering effect of the Cambrian limestone aqui- fer.
