矿产资源的生产对自然环境产生负面影响，这是可持续自然资源使用/管理方面迫切需要讨论的一个议题。在这项研究中，我们探讨了采矿活动的适当环境指标，这些指标可能易于说明，并被认为适合作为总体环境影响的一级估计。我们区分不同业务之间的差异影响，而不是提供严格估计的综合单一指标值。考虑到人们对土地利用变化及其影响的日益关注，选择生态足迹作为第一指标，并选择总物质需求作为生态足迹的补充。本研究以三个铜矿为案例研究，使用了业务卫星数据和遥感卫星数据。结果表明，EF的建设用地工程以及通过显示地上的影响，采矿活动和TMR补充EF的能力，以反映地下活动。
The production of mineral resources negatively affects the natural environment, which is a topic of urgent discussion in sustainable natural resource use/management. In this study, we explored appropriate environmental indicators of mining activities that might be easy to account for and deemed suitable as a first-order estimation of overall environmental impacts. We distinguish the differential impact between operations rather than providing a strictly estimated integrated single indicator value. Considering the increasing interests in land use change and associated impacts, ecological footprint (EF) was chosen as first indicator, and Total Material Requirement (TMR) was also chosen to complement EF. Both the operational and remote-sensing based satellite data were used in this study by using three copper mines as case studies. The results propose that EF for built-up land works well by showing above the ground impacts for mining activities and TMR complements EF with its ability to reflect the underground activities.
