摘要
基于并行采集方式的矿井三维直流电法作为传统高密度电法技术基础上的改进,具有采集效率高、数据量大、观测系统布置灵活等优势。鉴于煤矿探查回采工作面煤层顶板含水构造的实际需求,对矿井三维直流电法勘探进行研究,设计出O型观测系统进行井下全空间电位数据的同步采集,并采用相应的正反演算法,实现含水构造的三维全空间电阻率反演成像。相似的物理模拟实验与工程实际应用结果验证了矿井三维直流电法探测方法及反演解释手段在煤层顶板水害探查方面的有效性和可靠性。
As an improvement of the traditional high density electric method,the mine three-dimensional direct current method based on parallel acquisition has the advantages of high acquisition efficiency,large amount of data and flexible arrangement of observation system;in view of the actual demand of coal mine exploration of water-bearing structure in coal seam roof of mining face,the mine three-dimensional direct current exploration method is studied,and an O-type observation system is designed to carry out synchronous collection of underground full-space potential data,and the corresponding forward and inversion algorithm is adopted to realize three-dimensional full-space resistivity inversion imaging of water-bearing structure.The similar physical simulation experiment and engineering application results verify the validity and reliability of the three dimensional direct current detection method and inversion interpretation method in coal seam roof water damage detection.
