根据室内和野外的实验资料,提出某些消除围岩电性不均对联合剖面曲线干扰的方法.一、方法的实质在复杂地电断面上,每个测点的电场强度是给定点源电荷和所有组成复杂断面的各电性体(矿与非矿地质体)感应电荷系所产生的合成场的强度,它和每个电性体单独产生的电场相对值的乘积类似,可由以下经验公式表达:?式中ρ_复——复杂断面的视电阻率ρ_S;
According to the laboratory and field experiments, some methods to eliminate the interference of the electrical unevenness of the surrounding rock to the joint profile curve are proposed.One, the essence of the method On the complex geoelectric section, the electric field strength of each measuring point is given a point source charge And the strength of the resultant field produced by all the charge-inducing charge systems of all the electrical bodies (ore and nonmineral geological bodies) with complex cross sections is similar to the product of the relative values of the electric fields generated by each electrical body separately and can be expressed by the following empirical formula Expression: ρ where ρ_ complex - the apparent resistivity of complex sections ρ_S;
