基于三极装置的三维直流电法探水研究及应用

Research and Application of Three-dimensional Direct Current Electric Method for Water Exploration Based on a Triple Pole Device

为了保证陈蛮庄煤矿3602工作面底板不发生突水事件,需对工作面底板岩层进行富水性探测。通过采用直流电法三极装置对工作面底板进行探查,经处理后绘制3602工作面底板视电阻率三维数据体,并结合相关地质及水文资料,圈定了4个3602工作面低阻异常区。对低阻异常区进行了钻孔验证,发现该异常区富水性强。通过以上实例,说明三维直流电法的探测效果较好,具有很高的实用性。

In order to ensure that there is no water inrush event on the bottom plate of the 3602 working face in Chenmanzhuang Coal Mine,it is necessary to conduct water rich detection on the rock layer of the working face bottom plate.By using a direct current elecric method triple pole device to explore the bottom plate of the working face,a three-dimensional data volume of the apparent resistivity of the 3602 working face bottom plate is drawn after processing,and combined with relevant geological and hydrological data,four low resistance abnormal areas of the 3602 working face are delineated.Drilling verification is conducted on the low resistance abnormal area,and it is found that the abnormal area is highly water rich.Through the above examples,it is demonstrated that the threedimensional direct current electric method has a good detection effect and high practicality.
