等值反磁通瞬变电磁法在矿山采空区隐蔽致灾水害勘查中的应用

Application of the opposing-coils transient electromagnetic method in the survey of hidden disaster water hazard in Mining Goaf

等值反磁通瞬变电磁法具有抗干扰能力强、受场地限制小、分辨率高、不受高阻屏蔽、对低阻敏感等特点,广泛应用于工程勘查中。本次工作采用等值反磁通瞬变电磁法对地下富水采空区和导水裂隙、破碎带进行探测,取得了良好的效果,为矿山隐蔽致灾水害治理提供了参考。

Opposing-coils transient electromagnetic method is widely used in engineering investigation because of its strong anti-interference ability,small site restrictions,high resolution,not shielded by high resistance and sensitive to low resistance.In this work,the opposing-coils transient electromagnetic method is used to detect the underground water-rich goaf,water flowing fracture and fracture zone,and good results are achieved,which provides a reference for the management of hidden disaster-causing water in mines.
