矿山酸性排水的测量方法及评价

文章讨论了近年来提出的几种由于金属矿山(特别是金属硫化物矿山)的开采活动而导致酸性排水发生可能性的预测方法,其中,主要是针对产酸能力和酸中和潜力进行确定的静态实验室方法和计算方法,因为各有优、缺点,故给出了计算方法评价,并说明一些酸性排水预测结果检验技术。

Test methods of the acid drainage of metal mines and their evaluation

Metal mine exploitation,especially the mining activities on metallic sulfide mines,usually causes the acid mine drainage(AMD),which influences seriously the ecological environment. The methods to predict the AMD are discussed,including the stationary test methods used in the laboratory and the calculation methods. The acid potential(AP) and neutralization potential(NP) of the mining wastes should be determined in the test and calculation. An evaluation of the advantages and disadvantages of the methods is also made. Some techniques that can be used to examine the test results are presented.
