Integrated characterization of waste rock at the Detour Lake Mine

德图尔湖金矿的露天开采产生了大量废石，需要对其进行管理，以最大限度地减少酸性岩石废水的排放。1983年至1999年，在德图湖遗址进行的采矿作业导致建造了四个废石堆积场。其中两个库存是在目前的德图湖矿开发过程中挖掘出来的。目前仍有两个库存。这些储存库在现场条件下有16年的运行历史和15年的关闭后历史，是一个宝贵的机会来检查迪图湖遗址的岩石类型的反应性，可以用来改善水质预测。这些库存还提供了一个机会，以了解前一次作业后使用的废石关闭战略的执行情况，并为

Open pit mining at the Detour Lake gold mine is generating large volumes of waste rock that need to be managed to minimize the release of acid rock drainage. Previous mining operations at the Detour Lake site, from 1983 to 1999, resulted in the construction of four waste-rock stockpiles. Two of these stockpiles were excavated during the development of the current Detour Lake mine. Two stockpiles remain in place. These stockpiles have 16 years of operating history and 15 years of post-closure history under site conditions, and represent a valuable opportunity to examine the reactivity of rock types from the Detour Lake site, which can be used to improve water quality predictions. The stockpiles also provide an opportunity to understand the performance of waste-rock closure strategies used following the previous operation and provide a basis for
