中间梯度法和电测深法都是常用的物探工作方法,中间梯度法在金属矿普查中使用最多,工作效率较高,而对称四极电测深装置异常形态简单,易于解释,但是工作效率低。提出了一种兼具两种方法优点的工作方法——多极距中梯电测深。
Intermediate gradient method and electric sounding method are commonly used geophysical methods of work, the intermediate gradient method used in metal mine census most, higher efficiency, while the symmetrical quadrupole sounding device abnormal morphology is simple and easy to explain, but the work efficiency low. A working method combining the merits of the two methods is presented.
