Geochemical characteristics and the increase in the total reactive surface area of the AMD. The study of the changes of geochemical characteristics of sulphide-bearing rocks showed that the oxidation process in waste rock dump in 10 years was more advanced than that of 2 years. As the results of mineralogical investigation, the weathering is easy to accelerate around the surface of dumping area due to climatic conditions and acidification by oxidation of sulphides. Moreover, the study showed that the formation of clay minerals after the weathering processes took place at the dumping area, suggested that the generation of AMD would be minimized because the interior of the waste rock dump provided a barrier to oxygen and water. Moreover, some additional countermeasures should be taken into consideration at the same time such as the dumping method of waste rock and application of low-permeable layer.

地球化学特征和AMD的总反应表面积的增加。对含硫化物岩石的地球化学特征变化的研究表明，在10年内，废岩垃圾场的氧化过程比2年更先进。作为矿物学研究的结果，由于气候条件和硫化物的氧化酸化，风化很容易在倾倒区域周围加速。此外，该研究表明，在垃圾场发生了风化过程后的粘土矿物质形成，这表明将AMD的产生最小化，因为废岩垃圾场的内部为氧气和水提供了障碍。此外，应同时考虑一些其他对策，例如废岩的倾倒方法和可渗透层的应用。
