为了提高井下瞬变电磁水害探测准确性,降低探测过程中井下巷道存在的金属物及带电体对探测结果的影响。通过物理模拟、数值模拟等技术手段,对瞬变电磁测量的采集观测系统进行优化设计,对探测的电磁数据质量进行评估,结合瞬变电磁数据正反演算法软件的处理与校正,从而达到提高煤矿含水异常体的解释精度,及时预报掘进前方或侧帮的隐伏导含水构造,为煤矿能安全掘进提供有力技术保障。
In order to improve the accuracy of underground transient electromagnetic water damage detection and reduce the influence of the metal and charged body in the underground roadway on the detection results during the detection process, through physical simulation, numerical simulation and other technical means, the acquisition and observation system of transient electromagnetic measurement was optimized, and the quality of detected electromagnetic data was evaluated. Combined with the processing and correction of transient electromagnetic data forward and inverse algorithm software, the interpretation accuracy of water-bearing abnormal body in coal mine was improved, and the hidden water-bearing structure in front or side of excavation was predicted in time, which provided a strong technical guarantee for safe excavation of coal mine.
