摘　　要：为了研究新安煤矿13151采煤工作面煤壁侧底板奥灰突水机理,结合物探、钻探和数值模拟等成果,从径流带、原岩应力、奥灰水原始导升、采动矿压持续作用等方面做了综合分析。研究表明:本次突水是地下水径流通过、原岩应力、水压和矿压综合作用的结果;为避免奥灰突水,可综合使用瞬变电磁法、槽波地震等多种物探方法来提高预测效果,薄弱区注浆改造必须彻底有效,停采线应避免靠近物探异常区等薄弱区段。To investigate the mechanism of Ordovician limestone floor water inrush at the downside of coal wall in No. 13151 working face in Xin＇an Coal Mine, the following factors were analyzed, such as underground water runoff zone, stress of primary rock, original guide rise of Ordovician water and continued effect of mining pressure. The research results showed that the water inrush was the results of the combined effects of these factors. In order to avoid the water inrush in Ordovician limestone, the comprehensive utilization of transient electromagnetic method and channel wave seismic exploration method could improve effectively the forecast results, then grouting and reconstruction should be thorough and effective in weak zone, and the stopping line should be avoided closing to the risk area such as the geophysical anomaly zone.
