摘　　要：常规井下瞬变电磁超前探测技术存在体积效应,仅能确定富水采空区的方位,难以对其边界进行精确探测,为了查明朝阳煤矿9101巷道掘进前方的采空区及其富水情况,基于矿井瞬变电磁超前探测方法,采用瞬变电磁超前探测波场成像技术进行处理,结果表明,同传统全空间数据处理视电阻率结果相比,瞬变电磁超前探测波场成像技术能够确定采空区富水边界位置,波场曲线幅值同含水采空区出水位置对应较好,采空区的富水边界位置同全空间波场成像结果更为吻合。Traditional mine transient electromagnetic advance detection technology has volume effect.The technology can only detect the position of watery goaf,but it is difficult to accurately detect the boundary.In order to accurately detect the distribution and watery boundary of goaf in front of 9101 roadway in Chaoyang Coal Mine,advance detection data is processed by wave field imaging system based on mine transient electromagnetic method.The results showe that watery boundary position of the watery goaf can be delimited by the wave field imaging system.The amplitude of the wave field curve corresponds well to the position of the watery goaf.Boundary position of the watery goaf is more consistent with the wave field imaging results.
