A tailings dam is the most common waste disposal method for a mining company, whether it is mining iron ore, gold or copper.

尾矿坝是矿业公司处理废弃物最常见的方法，废弃物包括但不限于铁矿石、金子、铜。

Yet there are no established standards, or rules, defining what a tailings dam is, how to build one and how to care for a dam when it is no longer in use.

但目前并没有明确的标准、规定，没有关于尾矿坝的明确定义，没有规定如何建造并维护已经弃之不用的尾矿坝。
