本文以正演、模型实验、野外实例支持了固定点电源装置可作测深法的结论,探讨了该装置异常幅度与h、ρ曲线与R、MN、Y及组合球体的关系,指出ρ曲线极值点对应极距与矿体中心埋深近似相等。并对该装置的信号、克服覆盖层能力、地形和旁侧体对ρ曲线的影响进行了讨论,认为可用比值法压制地表局部不均匀体对ρ线的影响。该装置ρ曲线确定矿体中心埋深时,等值干扰不影响解的唯一性。专门将该装置与五极纵轴测装置进行对比,前者比后者布极简单,装备轻便,地质效能也优于后者,故能够取代五极纵轴测深法。该方法探明局部地质体应有独到功效,适于解决工程、水文以及其他找矿等地质问题。
In this paper, the conclusion that the fixed-point power supply device can be used as the sounding method is supported by the forward modeling, the model experiment and the field examples. The relationship between the anomaly amplitude, h, ρ curve and R, MN, Y and combination sphere of the device is discussed. The extreme points corresponding to the polar distance and the ore body center buried depth approximately equal. The influence of overburden abilities, topography and lateral body on ρ curve is discussed. It is considered that the ratio method can suppress the influence of local inhomogeneous bodies on ρ line. When the ρ curve of this device determines the depth of the orebody center, the equivalent disturbance does not affect the uniqueness of solution. Specifically compared with the five-axis longitudinal axis measuring device, the former is more simple than the latter, equipped with light, geological performance is also better than the latter, it can replace the five-polar longitudinal sounding method. The method proved that the local geological body should have its unique effect and is suitable for solving geological problems such as engineering, hydrology and other prospecting.
