酸性矿山废水是由含硫矿山废弃物经空气、水和细菌作用而产生的，由于其pH值极低和重金属超标，被认为是一种严重的环境污染物。为了解决矿山酸性废水带来的生态环境问题，人们开发了中和、吸附、钝化、生物抑制、物理覆盖等处理方法。然而，这些方法都是终端处理方法，无法从源头上防止酸性矿井水的产生。近年来，尾矿覆盖技术因其上级源头控制能力而备受重视。通过减少与空气、水和细菌的接触，硫化物尾矿的氧化作用显著降低，从而避免了酸性矿山废水的产生。迄今为止，人们已经对这些技术进行了大量的研究，部分技术已经得到应用，但对这些技术的原理、过程和应用的综述仍然缺乏。因此，本综述旨在增加与尾矿覆盖技术最相关应用相关的知识，包括以下方面：（i）尾矿覆盖技术的背景，概念和性能;（ii）每种尾矿覆盖系统的适用条件及其优点和局限性;以及（iii）该技术的未来前景。
Acid mine drainage, produced from sulfur-containing mine waste exposed to air, water, and bacteria, is considered as a serious environmental pollutant because of its extremely low pH and excessive heavy metals. In order to solve the ecological environment problems caused by the acid mine drainage, treatment methods such as neutralization, adsorption, passivation, bio-inhibition, and physical coverage have been developed. Nevertheless, these methods are terminal treatment methods, which are unable to prevent the generation of acid mine drainage at the source. Recently, it is noteworthy that the tailing covering technology is particularly emphasized, owing to its superior source control capability. By reducing the contact with air, water, and bacteria, the oxidation of sulfide tailings is significantly reduced, thus avoiding the production of acid mine drainage. To date, massive research has been studied and parts of technologies have been applied, but the review on the principles, processes, and applications of these technologies are still lacking. Thus, the present review aims to increase the knowledge related to the most relevant application of tailing covering technology with the following aspects: (i) the background, concepts, and performance of tailing covering technology; (ii) the applicable conditions for each tailings coverage system and their advantages and limitations; and (iii) the future perspective of this technology.
