摘要
依据电磁场理论,构建地电模型,利用有限差分对矿井三维地电异常体进行数值模拟,得到异常体在电阻率不同、至巷道距离不同、及测点不同情况下的层测深曲线,并对其分布规律进行分析研究。通过模拟矿井三维地质异常体地电异常响应特征,并与井下实测层测深曲线对比和分析,论证了矿井三维地电体数值模拟的正确性。
On the basis of theory of electromagnetic field, setting up a geoelectric model, carry out mine 3D geoelectric anomalous body numerical simulation through the use of finite difference method. We get electric sounding curves of the anomalous body in different resistivity, different distance to roadways and different survey station, and analyzed their distribution regular patterns. Through simulate mine 3D geoelectric anomalous body's geoelectric anomalous response features, and analyzed the contrast underground actual measurement sounding curves. Finally demonstrated the correctness of mine 3D geoelectric body numerical simulation.
