整合是成功采矿的关键

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

第一步是提高资源模型的信心和可靠性。PeñaColorada沉积物包括三个受中度断层系统影响的主要地质结构。这三个结构以最新的材料特征来控制地质。

The mineral resource model was constructed in two stages:

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

地质模型的构建涉及三个步骤：

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 MSIM has since been replaced by Geologic, which leverages the power of implicit modelling by sequencing surfaces and solids to create an airtight geological model.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."

此外，还准备了新的岩土工程研究，为坑坡设计提供了新的指南。实施了新技术来监视地面运动和坡度稳定性。

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.

维拉说：“但是，计划与现实之间总是有差异。”“通过采用一流的矿山计划软件和车队管理系统，这大大降低了。”

Before the FMS implementation the designed blasthole collars for the production drills had to be staked out by surveyors. During the rainy season, however, the weather would delay the surveyors and consequently delay the drills, which hurt production. After the implementation of the FMS, the planned/design blastholes are transferred digitally to the drill equipped with high-precision guidance for accurate blasthole location, so there is no need for the surveyors to stake out the collars in the field anymore. Now production stays on track.
