| 摘 要： | 介绍一种井下探测构造和含水体的三极电阻率法。它根据点电源电场在均匀介质中的球对称特点,采取一定的布极方式,利用岩性和岩层富水性的电性差异,通过分析异常场,不仅可定性判断地质体的富水性,还可定量判断异常场的方位及其与点电源的距离。实践证明,该方法可节省大量钻探工程,是矿井防治水中一种有效的物探手段。

| Abstract: | Method of three-electrode resistivity is provided for prospecting underground structure andaquifers.It is on the basis of the characteristics of the electric field of point source having a ball symmetry inhomogeneous medium and of certain electrod spread.By analysing the abnormal electric field and thedistinction of electrical para meters between good aquifers and poor aquifers,the water abundance ofgeological bodies can be qualitatively estimated.Further the direction of abnormal electric field and thedistance from the point source can be quantitatively indicated.It is proved that using this method,a great dealof drill projects can be decreased and this is an efficient and economic geophysical method for mine watercontrol. |
