摘　　要：金属矿产在开采过程中上覆岩层发生破坏,沟通顶板富水区,严重危害安全生产。为预防水害,应用矿井瞬变电磁法透视顶板区域,从而圈定富水区域。通过瞬变电磁法采集数据,经数据反演后,直观展示顶板高阻异常与低阻异常的分布范围。通过分析高阻异常与低阻异常分布,查明并圈定了富水区域11个,其中强富水性区域5个,中等富水性区域2个,弱富水性区域4个。结果表明:矿井瞬变电磁法应用于顶板富水区域探测、富水性研究效果良好,准确性较高,能够为水害预警提供可靠资料。During the mining process of metal minerals,the overlying strata are destroyed,and the water-rich area of the roof is communicated,which seriously endangers the safe production.In order to pre vent water disaster,the mine transient electromagnetic method is used to penetrate the roof area,so as to de lineate the water-rich area.The data are collected by transient electromagnetic method.After data inver sion,the distribution range of high resistance anomaly and low resistance anomaly of roof is visually dis played.By analyzing the distribution of high resistance anomaly and low resistance anomaly,11 water-rich areas were identified and delineated,including 5 strong water-rich areas,2 medium water-rich areas and 4 weak water-rich areas.The results show that the mine transient electromagnetic method is applied to the roof water-rich area detection and water-rich research with good effect and high accuracy,which can provide re liable data for water disaster warning.
