大功率激电测深在铜多金属矿勘查中的应用
|
摘要
文章介绍在矿区外围地区开展激电中梯、激电测深等工作,通过时间域激发极化法所测得视电阻率ρs和视充电率Ms电性异常特征,通过中间梯度法推测出铜多金属矿(化)体在平面上走向和范围,根据单机-偶极测深有效确定铜多金属硫化物矿体的空间位置,推测极化体的产状,取得较好的勘查效果。
In this article, the paper introduces the operation of the excitable medium ladder and the excitation sounding in the periphery of the mining area. Through the time domain excitation polarization method, the anomalous characteristics of the apparent resistivity(p s) and the apparent charge rate Ms are measured. The direction and range of the copper polymetallic ore(chemical) body in the plane are speculated by the intermediate gradient method, and the validity of the single machine dipole sounding is effective. The spatial location of copper polymetallic sulfide ore bodies is determined, and the occurrence of the polarizing bodies is predicted, and a better exploration effect is achieved.
