摘要: 为更好地解决井旁矿体的勘探及盲矿的预测问题,探讨了地-井方式激发极化法对于井旁的规则形体(矿体)的激电影响;采用解析投影法,以球体和板状体两种模型为例,遵循"单井—多井"的激电规律来判别矿体的空间位置. 最后,归纳总结出地-井方式激电在实际工作中的使用条件,能够快速判别井旁盲矿体的空间位置. 结论指出,合理的施工方式以及适量的观测数据对预测矿体的产状具有积极作用.Abstract: The surface-to-borehole IP method, as an actually widely used ore exploration means, has aroused a lot of interest among geologists both in China and abroad. In this paper, the authors probed into the IP effects of the surface-to-wells IP method on the regu-lar orebody beside the well so as to solve the problem of predicting the exploration of the orebody beside the well and the blind orebody. In this paper, the authors mainly studied the spherical and the platy orebodies of different IP modes on the generated curve,and then explored multi-well cases. Finally, the authors discussed how to determine the spatial location of the orebody based on multi-wells law. The results obtained by the authors are helpful to the related research fields. In conclusion, reasonable construction method and proper quantity of observed data have positive effect on the prognosis of the orebody.
