利用直流电法技术在探测煤矿岩层富水性时,顶板或者底板的低阻异常体彼此容易引起旁侧干扰,传统的数据处理过程并没有对其处理,致使成果图中出现一些假异常,给解释工作带来很大困难.为了准确探查目标区,本文基于以上问题,利用ANSYS软件自带的APDLP模块进行编程,建立全空间环境下不同位置异常体的三维模型,使用三极装置模仿现场数据采集,提取模拟数据并成图,得到不同位置异常体电阻率变化曲线,分析电阻率曲线变化特征,剔除旁侧干扰,为准确探测目标区岩层富水性打下基础.
When using direct current method to detect water-rich coal seam rock formations, the low-resistivity anomaly of the roof or floor easily cause side-by-side interference with each other, and the traditional data processing did not process it, resulting in some false anomalies in the results map, In order to accurately explore the target area, based on the above problems, this paper uses the APDLP module built in ANSYS software to program, build the three-dimensional model of the abnormal body in different positions in the full space environment, use the three-pole device to simulate the field data acquisition, The simulation data are extracted and plotted to get the curve of the resistivity variation of the anomalous body in different positions. The variation of the resistivity curve is analyzed, and the side interferences are removed, laying the foundation for accurately detecting the water-bearing property of the rock formation in the target area.
