随着煤矿综采机械化程度的提高,在采煤工作面发生突水事故时,准确查明突水水源位置及补给水源方向显得尤为重要.采用矿井瞬变电磁法“扇形扫描”探测技术,在采煤工作面预测突水点靠近的巷道内,距离工作面30～50 m,选择巷道环境较好位置进行数据采集,单个测点设计多角度探测,通过对采集的原始数据进行处理形成扇形图件,结合矿井水文地质资料综合分析,从而可确定采煤工作面突水水源位置和补给水源方向.%With the improvement of the mechanization degree of fully-mechanized mining in coal mine,the ability of detecting the position of the water inrush sources and the direction of the recharge water precisely is important when water bursting occurs on working face.In this paper,using mine transient electromagnetic method "sector scan" detection technology to predict the coal face on the water bursting point close to the roadway,from the face 30 ～ 50 m range,select the location of the roadway environment is better for data collection,at the single measuring point designing multi-angle detection.By processing the collected raw data form pie chart pieces,a comprehensive analysis was carried out combined with hydro-geological data of mine,which can determine the location of water bursting and direction of water supply sources on working face.
