摘要
主要介绍了在钻孔中放置供电电源、在地面进行测量的井—地三维电阻率成像数值模拟方法,将其空间分辨率与地面常规电法勘探进行了对比.详细研究了方法的仪器特性及其数据采集过程中的测网布置、装置形式、记录点、采样密度及供电点的深度位置等相关内容,并从中得总结得到了若干结论.
In this paper, we introduce the numerical simulation method for three dimension resistivity tomography of Mine-ground in which the power supply is placed in drill and the measure electrodes are working on the ground. Compare it's resolution with the normal electrical method's. We detail in studied the characters of instrument and the relational contents include the measure modes, array, recording points, sampling density and the power supply’s location in drill all that belong to the data collection process, from which we drew some conclusions.
