跨孔超高密度电法CT在采空区中的应用

Cross-hole High density Electrical Method CT in the application of the mined-out area

跨孔超高密度电法是利用在平行钻孔中布置电极,通过一孔中的两个电极供电,其余电极同时测量的一种电法勘探方法。它不仅比较准确地解决了孔与孔之间的电阻率问题,对场地要求较低且施工方便。通过对大龙潭采空区的3个钻孔进行施工,充分证明该方法在解决此类工程问题上的有效性和准确性。

The across the hole of the high density electrical method is proposed in the arrangement of electrodes, parallel drilling through a hole in the two electrode power supply, the rest of the electrode measured at the same time a electrical prospecting method. It is not only more accurately solve the problem between holes and hole resistivity, low requirement for site and construction is convenient. Through to dalongtan electrical prospecting mined-out area of three drilling, fully proved the effectiveness of the proposed method to deal with the problem of this kind of project and accuracy.
