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)

一个多边形中的2,000吨潜在的2,000吨是一个用于稀释控制的系统。

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.
