掌握地雷的大数据

三年前，墨西哥的Del Mayo（CDM）试图在其位于索诺拉南部的开放坑铜矿上解决常见但复杂的问题，距阿拉莫斯镇21公里。那时，公司开始使用Hexagon Mining的车队管理解决方案。bob体育报道结果令人印象深刻。

Three challenges to overcome
The geology of the mine presented CDM with its first mining challenge. CDM produces grade-A copper cathode, supplied as refractory, and vein-type ore for processing into concentrate. The mine is a copper porphyry system, structurally controlled by shear faulting with mineralisation stockwork, disseminated and variable depth ranging oxidation.

Oxidation is from the surface up to 430 metres, with chalcocite from 40 to 430m. The challenge lies in two types of minerals that cannot be processed the same way. The dominant alteration is quartz-sericite and sporadic areas with intense argillic alterations, meaning that close control is essential in the dilution and the selectivity of the ore.

The next challenge to overcome was fleet management.
CDM’s fleet comprises the following:

• Three hydraulic shovels, Komatsu and Terex
• 两个复古挖掘机，Komatsu和Caterpillar
• 三个装载机和三个高精度第一加载器
• 26 haul trucks (20 789s and six 777s)
• 三个练习，Sandvik，D75KS和一个高精度的推土机
• Auxiliary equipment, including dozers, graders and water trucks
• Retro excavators, which are roughly the size of the ore polygons (deposit areas)

The potential 2,000 tonnes in one polygon make a system for dilution control essential.

最后，跟踪和报告可能是一项压倒性的任务。

CDM must deal with waste in various forms, from low-grade to medium- and high-grade. Constant awareness of waste type is important because the loading equipment can be working with three or more polygons simultaneously, requiring frequent changes from truck to truck. So, like any mine, fleet management is important to CDM. The complicated ore distribution means CDM’s teams of operators must use the best tools to avoid dilution and improve selectivity.

Even great systems and great tools can fall short, however, if reliable and accurate reporting is not part of the process. Since CDM began commercial production in 2006, operators had compiled reports manually in the absence of an automated reporting process. Truck operators would include their cycles from origin to destination, and the dispatcher would capture all the information from the operators by hand and compile them. CDM tracked usage times and equipment delays by hand and by radio. Real-time alerts of delays were unavailable and receiving reliable data from the drill operator was difficult. Without a system to automate tracking and reporting, valuable time was being squandered.

Hexagon Mining solution selected
Hexagon Mining’s fleet management solution, Jigsaw, was among six systems evaluated by CDM to help solve these issues. After careful analysis, CDM selected Jigsaw.

“The best option was Hexagon Mining,” said CDM’s Dispatch Manager Victor Rodriguez. “The evaluation process was done in the form of a cost evaluation, as well as with a group of people who visited various mines. Most of them were in Chile and observed firsthand the Jigsaw system working.”

The system installation included a room for the dispatch in the highest part of the mine. This offered a full view of mine operations via visual controls. Three 52-inch screens were installed to display different dashboard views of the mine. Each dispatcher was supplied with three additional 32-inch screen displays. The smaller screens manage the roads on Jview and allow for realtime reports. The other dispatcher handles control of the operation and production equipment, including loaders and trucks.

清洁发展机制的核心implementation timeframe from first installment to go-live was roughly three months. Like most mines, CDM’s overriding objective is to produce more while lowering costs. Armed with Hexagon Mining’s fleet management solution, CDM was quickly able to increase safe mining operations and production output, while managing cost, quality and control.

Real-time information for better decision making
Now CDM has designated maintenance dispatchers equipped with the proper notification systems, preventing maintenance issues from draining time and resources. Operators needing support or experiencing problems with equipment can speak directly with maintenance or text messages from the system, thus reducing radio frequency demands.

The primary crusher is now monitored in real time. Any delay generates an immediate alert, avoiding the need for phone calls or radios, which can sometimes be unreliable. Individual dumps in the crusher, waste, leach pads, and stockpiles are monitored and reported on. With multiple destinations, every truck is unloading exactly where and when it needs to be.

“Prior to partnering with Hexagon Mining, it had been extremely difficult for us to achieve precision in our extraction, given the size of our equipment,” said Rodriguez. “Since the implementation, significant improvements have been achieved in our ore control, as can be seen in our current production increases.

“The solution provides reliable and flexible and automatic reporting, for production, productivity, availability, drilling information, and many other aspects of the mine operation,” concludes Rodriguez.
