整合是成功采矿的关键

Hexagon Mining customer, Pena Colorada, is one of the largest iron ore operations in Mexico. Located in the state of Colima, Pena Colorada's operations consist of an open pit mine in Minatitlán and a pellet plant in the port city of Manzanillo.

尽管每年的浓缩量为每年410万吨，但PeñaColorada仍面临矿石成绩下降。作为回应，该公司必须进一步扩大生产。这种扩展带来了挑战，这些挑战通过采用和应用新技术以及改进地板，矿山规划和矿山运营而克服了挑战。

这些技术的成功实施已多次支付，并导致了生产和绩效的显着改善，同时降低了运营成本并减少了计划和执行之间的差异。

善于做好

The first step was to increase the confidence and reliability of the resource model. The Peña Colorada deposit comprises three main geologic structures affected by a moderate fault system. These three structures control the geology in terms of minable material characteristics.

The mineral resource model was constructed in two stages:

1. 地质模型的建造
2. Numerical modelling of attributes

地质模型的建造involves three steps:

1. Processing of the drilling campaign
2. 计算地质解释的最低规模
3. 构造周围固体。

The drilling campaign was processed through Hexagon Mining's mine planning suite, MineSight; specifically, its drillhole manager, MineSight Torque, and its 3D visualiser, MineSight 3D.

The geological envelopes were constructed as geometric solids using MineSight Implicit Modeler (MSIM) to accurately characterise the geological contacts. MSIM has since been replaced by Geologic, which leverages the power of implicit modelling by sequencing surfaces and solids to create an airtight geological model. The numerical modelling of attributes comprises the estimation of grades by localised ordinary kriging.

Once the block model was completed, new optimisation studies were evaluated with MineSight Economic Planner (MSEP) and new production schedules were completed with MineSight Schedule Optimizer (MSSO), which improved many aspects of the mine plan. For example, MSSO was used to evaluate and optimise the dump discharge plan.

从计划到现实

The results of the optimisation generated a plan with less stripping required in the earlier periods and a combination of short and long dumps, which balanced the truck hours over the life of the schedule and reduced the number of trucks required. The estimated gains from this optimisation study amounted to approximately $35 million in project value.

同样，MSSO也被用来评估扩展项目和更大的铁锹（P＆H 4100 XPC）和更大的卡车（CAT 789C和793F）。

"Mine expansion projects cost millions, if not billions of dollars," said Jose Villa, head of mine planning, Peña Colorada. "Investing in MSSO is easy to justify since it can guide important capital investment decisions and it costs less than the tires of an off-highway haul truck."

Additionally, new geotechnical studies were prepared, which provided new guidelines for pit slope design. New technology was implemented to monitor ground movement and slope stability.

Pena Colorada implemented Hexagon Mining's fleet management system (FMS) to monitor the operation and ensure plan execution and compliance. This enabled the company to capture in the field the value of the project as forecasted in the mine plan.

"However, there is always a variance between plan and reality," said Villa. "This has been significantly reduced with the adoption of best-in-class mine planning software and fleet management system."

在FMS实施之前，必须由测量师固定设计的生产钻头的Blasthole项圈。然而，在雨季，天气会延迟测量师，因此延迟了演习，这损害了产量。实施FMS之后，计划/设计的蓝晶石将以数字方式转移到配备高精度指南的钻头上，以确保准确的Blasthole位置，因此不再需要验证师将领域的项圈放在现场中。现在生产保持正轨。

"Hexagon Mining's mine planning software and fleet management system has narrowed the gap between what is and what should be," said Villa. "It has helped to unlock and realise significant project value."
