Ore Control Technological Innovations at Goldcorp Peñasquito Mine

作者：Christian H. Calderón Arteaga

Peñasquito位于墨西哥的Zacatecas State的东北角，是墨西哥最大的黄金生产商，由两个开放坑 - Peñasco和智利科罗拉多州组成，其中包含金，银，铅和锌。采矿（预动图）始于2010年，并于2011年全部产量。开阔的矿山矿山均供应硫化物浓缩器（磨坊）和堆浸垫。Peñasquito的项目归Goldcorp，Inc。拥有，是金属矿床，带有黄金，银，锌和铅作为应付金属的回收。

新的矿石控制技术

Due to expected lower grade ores with advancing mine-life, Peñasquito is facing a declining metal production profile. The requirement of the ore control system to accurately predict ore feed characteristics is critical to maximising metal recovery at Peñasquito, while the ability to accurately route materials from the ore control system is critical to site success. These challenges have been overcome by the adoption and implementation of a new ore control (OC) technology from Hexagon’s Mining division.

该解决方案改善了地段，材料路由和模型对帐。该技术的实施也显着提高了选择性，性能和数据管理，同时减少了计划和执行之间的差异。这有助于推动整个操作的整体改进。

该项目需要管理Blasthole数据，模型插值和模型计算以及其他相关任务。还需要创建新的矿石控制数据库，以管理材料路由，每日采矿，模型对帐以及与矿山的第三方系统的通信。实施的解决方案使用Blasthole数据库作为主要输入，同时还用作车队管理系统的材料路由输入，并作为生成各种报告。The OC system data is turned into information that supports the decisions and evaluation making processes at the mine.

从弱到明智的工作流程

Peñasquito的矿石控制团队用于更新OC模型的过程存在问题：缺乏对用户的中间步骤的了解，多数步骤的数量以及在过程中出现错误时进行故障排除的能力。这些问题阻止了Peñasquito运行强大的矿石控制模型，这可能对矿山的新需求负责。团队在模型中寻求更大的信心和可靠性。

这个旧过程被较新的，standardised workflowthat allows the users to trust in the results and to make informed decisions with higher confidence. Using HxGN MinePlan Operations (formerly MineSight Axis), a new workflow for Peñasquito’s OC was designed and implemented. The new workflow includes the usage of different tools to解决使用先前过程面临的矿石控制器面临的问题。

“多亏了新技术，我们提高了模型的可靠性，从而提高了对我们的储备的信心，”said Juan Barrios, ore controller for Peñasquito。“We have also reduced the working time to process a blast polygon, and now we can visualise and report the results almost in real time.”

改善矿石控制过程

The implemented solution includes new tools to:

• 管理OC模型更新过程
• 管理多边形路由和进度
• 向所有矿山消费者报告并发布必要的信息
• 运行模型对帐，其中将勘探模型与OC模型进行比较。

These tools were placed together in一种自定义设计，使他们能够在逐步的过程中工作。Information flows between the tools so the users can report the necessary information to make informed decisions with more confidence.

自实施以来，已经记录了定性，定量和抵押品的改进。

Qualitative improvements include:

1. a) Data security has improved by implementing the usage of SQL server technology;
2. b）现在，该过程是通过自动计算自动化的，即：OC剪切的自动命名，或基于块模型的储备金的切口的自动材料分配；
3. c) Process is auditable, meaning that the results are repeatable even after a long period of time;
4. d）用户现在可以与数据进行交互以做出明智的决策。

Quantitative improvements include:

1. a) The new OC process is much faster with an average reduction of 75 per cent in the processing time;
2. b) Monthly reconciliation processing time was reduced by approximately 80 per cent.

抵押品改进包括：

1. a) Density calculations are now reconciled between exploration and OC models;
2. b）新坑已经开始，不需要其他项目设置；
3. c）实施了针对规划部门可用材料的新预测报告；
4. d）现在可以实现新的每日和每周对帐报告，并由最终用户实施。

新矿控制系统的实现rom Hexagon’s MinePlan software narrows the gap between what is and what should be. The software helps to not only shape smart change, but also to unlock and realiseOC过程的重大改进。
