Canadian companies are responsible for nearly half of mining activities worldwide, and mining operations are expanding in Canada; creating jobs and revenue for the country and providing necessary resources for society. The KGHM Ajax project is a proposed mine near Kamloops, BC that is in its operational and environmental planning phase. The provincial government has identified the protection of the environment as a key component of mineral exploration and mining. Towards this goal, the BC Mines Act includes legislation for mine closure. Ecological restoration is a developing field of science that is ideally positioned to provide the knowledge tools for successful recovery of disturbed lands due to the extraction of metals in the mining process. We propose a fully factorial experimental design on mine tailings to test the effect of plant species seed composition (natives and agronomics), a nurse plant (sage brush) and ash as a carbon supplement on the development of the soil and plant communities. The research will provide essential information for the restoration of an historic Afton tailings storage facility owned by KGHM International Ltd. The information will also be critical for future reclamation of mine tailings at other mines in the southern interior of BC.

加拿大公司负责全球近一半的采矿活动， 在加拿大扩张;为国家创造就业机会和收入，并为社会提供必要的资源。 KGHM Ajax项目是一个位于不列颠哥伦比亚省坎卢普斯附近的拟建矿山， 规划阶段。省政府把保护环境确定为一个重点 矿产勘探和开采的组成部分。为实现这一目标，《不列颠哥伦比亚矿业法》包括以下立法： 矿井关闭生态恢复是一个发展中的科学领域，其理想定位是提供 成功恢复采矿金属开采造成的扰动土地的知识工具 过程我们提出了一个完全析因的实验设计，对矿山尾矿，以测试植物物种的影响 种子组合物（本地人和农艺学），一个护士植物（鼠尾草刷）和灰作为碳补充剂上 土壤和植物群落的发展。这项研究将提供必要的信息， KGHM国际有限公司拥有的历史性Afton尾矿储存设施的恢复。信息 对于不列颠哥伦比亚省南部内陆其他矿山未来的尾矿回收也至关重要。
