尾矿概述
Phu Bia Mining operate two Tailings Storage Facilities (TSFs), Phu Kham TSF and Ban Houayxai TSF.
普巴矿业的两个尾矿坝均由土石填充的横谷主堤坝、鞍形坝和泄洪道组成。堤坝为土石填充堤坝,包括低渗透区、内部过滤区和下游粗结构区。普巴矿业的尾矿坝采用下游施工方法建造,与中心线或上游施工相比,该方法被采矿业普遍认为是最安全的堤坝施工形式。三种施工方法示意图如下:



富康铜金矿和班会赛金矿尾矿坝均设计有泄洪道结构,旨在可以让最大洪水量安全通过,相当于 1:10,000 年一遇的洪水事件。我司已实施适当的处理和环境监测,以证明排放的所有水均符合行业规定。
两座尾矿坝的设计、建造和运营均符合国际大坝委员会和澳大利亚国家大坝委员会的国际标准。
两座尾矿坝的主要特点如下表所示:

普巴矿业举措
普巴矿业致力于建设对环境和社会负责的尾矿管理,以最大限度地减少对人类和环境的健康和安全影响。
普巴矿业已建立全面的尾矿管理系统,包括泛澳公司尾矿治理标准、尾矿审查委员会章程和普巴矿业采矿作业、维护和监控手册。治理标准明确规定了责任和义务、原则和标准,并鼓励持续改进,因为我们将会逐步改进以提高长期安全和环境绩效。泛澳公司尾矿治理标准基于国际准则,包括 MAC、CDA、ICOLD、ANCOLD 和 GISTM。
PanAust has appointed roles that align with the Global Industry Standard on Tailings Management (GISTM). The PBM Managing Director is the appointed Accountable Executive and is accountable for the safety of the tailings facilities. The appointed Responsible Tailings Facility Engineer (RTFE) is the Tailings and Geotechnical Manager. The RTFE is accountable for the integrity of the tailings facilities and is familiar with the design basis, design report and the construction and performance of the tailings facility.
A Tailings Review Working Group (TRWG) is utilised at PanAust to co-ordinate Governance and Management of the TSFs to ensure that strategy and decision making can be practically implemented. The TRWG objectives include informing the Executive Chairman about material risks, overseeing actions related to material risks and providing the necessary support and resources, and agreeing strategic decisions pertaining to the TSF. The TRWG is an internal function and the members include the PanAust General Manager – Project Studies, PanAust Group Manager Risk and Sustainability, PBM Managing Director, PBM General Manager of Growth and Development, PBM General Manager of Operations, PBM Tailings and Geotechnical Manager and PBM Risk Manager.
我们已从一家知名工程公司聘请了一位经验丰富的工程工程师。这位工程师 负责尾矿坝的设计和施工,并负责工程检查和相关报告。尾矿工程师为普巴矿业矿业尾矿团队提供持续支持,并与普巴矿业矿业工程师保持定期联系,包括每周会议。尾矿工程师每年进行三次检查,包括年度大坝安全审查 。尾矿独立审查小组和尾矿管理领域的专家每年进行的独立审查,一家知名工程公司每三到五年完成一次第三方综合大坝安全审查。
为了符合 全球尾矿管理行业标准披露要求,泛澳公司发布了一份符合 GISTM 要求 15.1 B 的普巴矿业尾矿设施披露报告。最新的披露报告可从以下链接下载:
