采矿作业会产生大量废物，这些废物通常储存在大型储存设施中，这会造成重大环境问题，必须进行适当监测，以管理灾难性故障的风险，并控制受污染的矿井排水的产生。在这种情况下，延时电阻率断层扫描（TL-ERT）等非侵入性监测技术很有前景，因为它们提供了大规模的地下信息，可以补充地面观测（步行、航空摄影测量或遥感）和传统监测工具，而传统监测工具通常对采矿废物储存设施的一小部分进行采样。本综述的目的如下： (i) 了解 TL-ERT 各种应用的研究现状； (ii) 为 TL-ERT 和地电监测采矿废物的未来研究创建参考图书馆； (iii) 根据我们的经验确定该问题的有前途的发展领域和未来的研究需求。本综述描述了地电监测的理论基础，并通过包含 650 多个案例研究的数据库（不限于采矿作业（例如滑坡、永久冻土））概述了过去 30 年的 TL-ERT 应用和发展。该综述特别关注 ERT 在采矿废物表征和监测方面的应用，并使用包含 150 个案例研究的数据库来确定采矿废物岩土工程和地球化学稳定性长期自主地电监测的有前景的应用。讨论了更广泛地采用 TL-ERT 监测采矿废物可能出现的潜在挑战。该审查还考虑了长期监测的仪器、数据采集、处理和解释方面的最新进展，并提出了未来的研究观点和有前途的途径，这有助于提高未来采矿废物中地电监测项目的设计和准确性。
Mining operations generate large amounts of wastes which are usually stored into large-scale storage facilities which pose major environmental concerns and must be properly monitored to manage the risk of catastrophic failures and also to control the generation of contaminated mine drainage. In this context, non-invasive monitoring techniques such as time-lapse electrical resistivity tomography (TL-ERT) are promising since they provide large-scale subsurface information that complements surface observations (walkover, aerial photogrammetry or remote sensing) and traditional monitoring tools, which often sample a tiny proportion of the mining waste storage facilities. The purposes of this review are as follows: (i) to understand the current state of research on TL-ERT for various applications; (ii) to create a reference library for future research on TL-ERT and geoelectrical monitoring mining waste; and (iii) to identify promising areas of development and future research needs on this issue according to our experience. This review describes the theoretical basis of geoelectrical monitoring and provides an overview of TL-ERT applications and developments over the last 30 years from a database of over 650 case studies, not limited to mining operations (e.g., landslide, permafrost). In particular, the review focuses on the applications of ERT for mining waste characterization and monitoring and a database of 150 case studies is used to identify promising applications for long-term autonomous geoelectrical monitoring of the geotechnical and geochemical stability of mining wastes. Potential challenges that could emerge from a broader adoption of TL-ERT monitoring for mining wastes are discussed. The review also considers recent advances in instrumentation, data acquisition, processing and interpretation for long-term monitoring and draws future research perspectives and promising avenues which could help improve the design and accuracy of future geoelectric monitoring programs in mining wastes.
