Abstract：
Source control of mine drainage and leachate from mining wastes is ideal, but there is limited use of control methods aside from removal of wastes to repositories or capping wastes in situ. In some locations, neither removal nor capping is possible; thus, there is renewed interest in understanding technologies for coating mining wastes. This paper presents the current state of knowledge from a critical review of the few field case studies where chemical coating technologies have been applied to mined surfaces (e.g. a highwall) or mining wastes. It also includes laboratory studies where the same technology was examined on the same type of waste material as the field studies. The chemicals used in field studies for coating mining wastes were magnesium oxide, potassium permanganate, silicate compounds, phosphate compounds, and a furfuryl alcohol resin sealant. Descriptions of the methods employed, and results obtained are provided. Limitations of the individual studies and of the technologies in general are discussed. Potential reasons why coating technologies have not been commonly used are presented, along with further research needs.
摘要：
矿井排水和采矿废物渗滤液的源头控制是理想的，但是除了将废物转移到储存库或就地覆盖废物之外，控制方法的使用有限。在某些地方,既不可能移除也不可能封盖；因此，人们对了解采矿废物涂层技术的兴趣再次增加。本文通过对化学涂层技术已应用于开采表面（例如高墙）或采矿废物的少数现场案例研究的严格审查，介绍了当前的知识状态。它还包括实验室研究，其中对与现场研究相同类型的废物进行了相同的技术检查。在现场研究中用于涂覆采矿废物的化学物质是氧化镁，高锰酸钾,硅酸盐化合物,磷酸盐化合物，和糠醇树脂密封胶。所采用的方法的描述，并提供了获得的结果。讨论了个人研究和一般技术的局限性。提出了涂料技术尚未普遍使用的潜在原因，随着进一步研究的需要。
