Drawpoint hang-ups represent significant impediments to getting the resource out of the ground in the safest, most expedient way, while oversize blocks of ore are tough for scoops to handle. So the business case for keeping the ore flowing is compelling. A MacLean blog post on addressing the gap between block caving animations and block caving real-life. www.macleanengineering.com

Whether it’s a low hang-up in a drawpoint, or oversize rock on the ground that’s too large for scoops to handle and too disruptive to get rid of with concussion blasting, it’s your secondary reduction rig that solves the problem and ensures that production isn’t held up. And when it’s not tasked with this mission, it can be put to use for ancillary drilling for mine services. www.macleanengineering.com

Drill productivity comes down to two critical factors: speed and accuracy. Sure, an operator can push a drill to its limits and produce a lot of vertical footage quickly. But if the resulting holes don’t stand up or if they’re the wrong depth or in the wrong place, it can result in time-consuming rework, a less-than-ideal shot and unnecessary drill wear and high consumables costs.

This video provides an example of the content and structure of a Performance Associates International computer-based operator training program. In this video, we focus on the user experience of our eLearning module for operators in a gold mill grinding circuit. This example demonstrates the following program features: • Language toggle controls. • Interactive process flowsheets. • Process descriptions. • Principles of operation. • Workbook feature. • Equipment (SAG mill) 3D animation. • Process variables. • Control loops. • Interlocks. • Alarms. • Interactive plot plan. The grinding circuit is just one of 11 modules included in the complete plant operator training program. Each individual module covers the technical aspects of a specific plant area. The program also contains modules presenting basic introductions to many applicable unit operations and a variety of basic mechanical skills. Additionally, detailed maintenance training modules cover each significant piece of equipment in the plant. A comprehensive training component to develop supervisory skills is included as well. Building, running, and maintaining a new plant is a significant investment. A work-force well-trained from top to bottom is the best way to protect that investment by ensuring a successful start-up and continued operations at peak performance. If you are building a plant and preparing your operators and supervisors for start-up and operation, please stop and ask the question “what components of this training program do I NOT want my operations team to be thoroughly familiar with?”

Although many mines and processing plants have sophisticated maintenance cost information systems, cost control relies ultimately on management actions based on the information such systems generate. A systematic management approach to solving problems and implementing solutions is the key to effective maintenance cost control

Effective plant-specific computer-based training (CBT) used in a formal training program can make the difference between a successful start-up and a failure. Or, in the case of an existing plant, it can make a huge difference in the effectiveness of operating results—particularly if turnover of experienced personnel is a factor. Once the plant process design and control strategies have been established, equipment has been ordered, and the plant is either operating or under construction, the only major variable affecting success is the capability of plant operating personnel. It is essential that the myriad details concerning plant operation are documented in a comprehensive CBT system suitable for training the non-technical personnel who will operate the plant.

In this training module, Performance Associates International (PAI) covers the characteristics of a gyratory crusher that’s designed to be the first stage in the size reduction of run-of-mine ore. A gyratory crusher receives ore from a mine and crushes the ore between a gyrating main shaft and stationary liners called concaves. This module explains the gyratory crusher’s principle of operation and provides detailed descriptions of the major components and the role that each component plays in its operation. You'll learn how the drive system operates, the details of the dust sealing system, the importance of the various lubrication systems, and the two functions of the main shaft positioning system, or MPS. We’ll also explain the operation of the balance cylinders and how they’re designed to prevent oversize boulders from causing damage. We’ll also cover the apron feeder, which conveys the crushed ore from the crusher to a downstream discharge conveyor belt. The principle of operation and detailed descriptions of the components of the apron feeder—including the drive chains, pans, rollers, and an electric or hydraulic motor—are illustrated. This is one of many plant area modules that is covered in a typical PAI operations training module.

What would it mean to your process if the variation in your key process variables could be cut in half? For example, consider greatly reduced variation in: • Leach circuit pH. • Thickener flocculant concentration. • CIL circuit cyanide concentration. • Cyclone feed density. Do your operators know if variation is random or non-random? If your operators were more familiar with the process control methodology, would it make a difference? What would be the result if your operators could troubleshoot and optimize each process control loop? At Performance Associates International (PAI) we believe that if the process variables in the plant are controlled at or very near their individual target ranges, the plant should be operating at near optimal efficiency. This translates into the lowest operating cost per unit production. This white paper describes how PAI approaches this component of training for your specific plant. We train on your process variables, their target ranges, the method of controlling those process variables, as well as the impact on the process if the process variables are not properly controlled.

Far too often, natural resource companies start up new plants without a properly trained operations and maintenance team. The results can be disastrous for both safety and revenue. Obviously the ultimate objective is a plant that operates in a safe and profitable manner. In most cases, the pre-start-up safety training is satisfactory, resulting in few if any accidents during start-up and ongoing operations. However, many plants drop the ball when it comes to properly training operations and maintenance personnel. The payback on a properly executed training program far outweighs the cost. If you are going to budget for high-quality engineering, efficient procurement, and experienced and proven construction management (including commissioning), why leave training open to chance? Performance Associates International (PAI) developed an extensive operations and maintenance training program for Torex Gold’s El Limón-Guajes project in the state of Guerrero, Mexico. In 2015, PAI industry training specialists traveled to the project site to carry out the training for Torex Gold employees in anticipation of plant start-up and gold production. The venture was a “massive success,” according to Nelson Bodnarchuk, Director, Operational Systems. This video tells the story of that success, including generous feedback from the executive officers at Torex recognizing our role in the partnership.

Con demasiada frecuencia, las compañías de recursos naturales ponen en marcha plantas nuevas sin contar con un equipo de operaciones y mantenimiento debidamente capacitado. El resultado puede ser desastroso tanto en términos de seguridad como de ingresos. Obviamente el objetivo fundamental es una planta que funciona de forma segura y rentable. En la mayoría de los casos, la capacitación sobre seguridad que se da antes del arranque de la planta es satisfactoria, resultando en pocos accidentes (o ninguno) durante la puesta en marcha y operaciones subsecuentes. Sin embargo, muchas plantas son negligentes cuando se trata de la buena capacitación de su personal de operaciones y mantenimiento. Un programa de capacitación bien ejecutado compensa con creces los costos de ejecución del mismo. Si se va a presupuestar una ingeniería de alta calidad, un proceso de adquisición eficiente y una gestión de construcción experimentada y comprobada (incluyendo el comisionamiento), ¿por qué dejar a la suerte la capacitación? Performance Associates International (PAI) desarrolló un programa de capacitación por computadora comprensivo, el cual abarca operaciones y mantenimiento, para su planta de oro El Limón-Guajes en el estado de Guerrero, México. En el 2015, los especialistas de capacitación industrial de PAI viajaron al lugar del proyecto para entrenar a los empleados de Torex Gold en anticipación de la puesta de marcha de la planta y la producción de oro. El emprendimiento fue un “éxito masivo,” según Nelson Bodnarchuk, Director, Sistemas Operacionales. Este video cuenta la historia de ese éxito, incluyendo comentarios generosos de los oficiales ejecutivos de Torex, quienes reconocen nuestro papel en la colaboración.

483 MSHA reportable injuries involving jacklegs occurred at US mines between 2003 and 2012, according to a recent study published by NIOSH (Clark et al., 2016). And these are just the reportable injuries - if you consider the “Heinrich Safety Triangle”, this can be viewed as the tip of the iceberg. What are the options for mechanization?

Project goal is to remove a small section of bench and creating a final wall catch bench without disturbing neighboring homes within 750 feet of blast area.

An application to determine how various blast patterns proposed for a project would perform in the field.

A fragmentation model developed in-house by Dyno Nobel was employed to model the fragmentation that would result from changes in the various blast design parameters.

The use of SHA (Signature Hole Analysis) and electronic detonators allowed the mine to dial in optimum timing sequences regardless of the number of holes per delay, resulting in reduced vibration and better digging rates allowing for faster removal of overburden.

As a new mine starting up development, this gold mine in Northern Ontario used much of the blasted rock for infrastructure in building up roads and construction pads.

This operation was undergoing a complete review of its blasting practices and blast designs in order to ensure the most optimized results were being achieved.

Using Differential Energy, Dyno Nobel was able to reduce the number of boulders at a quarry without adding more blast holes.

Dyno Nobel’s Titan ∆E 1000 was trialed over a period of four (4) months at AngloGold Ashanti's Cripple Creek & Victor Gold Mining Co. (CC&V) in Cripple Creek, Colorado. Performance of the Titan ∆E 1000 product was measured against typically loaded production blasts of similar size, in similar geology. Blast designs (drill pattern and blast hole sequence) for the performance and baseline blasts were not altered during the trial, and all blasts, except for one, were initiated using Dyno Nobel’s DigiShot® Plus electronic initiation system. Measured results confirmed that significant value in productivity, cost and blast performance were delivered. The mine reduced its overall powder factor by 18%, realized an 8% increase in shovel productivity in both waste and ore, and in the case of ore, experienced no reduction in crusher throughput. Additionally, they completely eliminated visible NOx after blast fumes in even the wettest areas of the pit.

The primary benefit from the TITAN emulsion technology is being able to note on the post blast reports that no postblast NOx fumes were present. Additional benefits include increased water resistance, increased actual energy yield verses theoretical value, increased product sensitivity resulting in high order detonation, ability to control density, redistribution of energy, increased detonation pressure, same cost per loaded foot, greater fragmentation versus cast movement, and allowing emulsion to be loaded to a lower density in highwall row resulting in the same pounds stretched to a greater height. Success measurements in the overburden truck/shovel blasts included consistent productivity (bucket fill times and bucket volumes) even in harder material located below the sandy strata, reduced post blast NOx fumes based on fume classification chart, few shovel operator complaints, and equal or reduced drill and blast budget. Seventeen blasts were completed without NOx fumes. The pounds per loaded foot was reduced from 51.5 with 40/60 HANFO to 43.1-47.1 range loading TITAN XL 1000. The average difference lbs/ft = 12.36% when 7.6% was needed for cost neutral. Stemming height was reduced from 22 ft to 20 feet to improve surface material displacement. Success measurements in the coal blasts included no roll crusher plugs from slabs, improved shovel production through uniform fragmentation, and equal or reduced drill and blast budget. Ten blasts were completed over afive-week period with no post blast fumes. There was good material movement, uniform fragmentation and generally no complaints or negative comments from shovel operators. Average difference lbs/ft = 11.98% when 4.5% was needed for cost neutral. Pounds per loaded foot averaged 45.33 compared to 51.5 with HANFO.

A review of seismic data from both blasts showed a twenty percent reduction in vibration using the timing solution developed using DYNO 42 compared to competitor timing sequence.

After speaking with Dyno Nobel, the mine decided to implement BlastWeb®, a centralised blasting system that is specifically designed for use in underground mining operations. BlastWeb allows reliable remote initiation of development, production and stope blasting from a safe and controlled location on the surface. The blast areas can be completely evacuated as no-one is required to be underground for the blasting. In addition to the obvious safety benefits, the other main benefit of the system at this mine is a reduction in the re-entry time. After the implementation of BlastWeb, a comparison was made of the blast completion times before and after its introduction. It was determined that centralised blasting reduced the blast completion time, on average, by 10 minutes. The implementation of Dyno Nobel’s Centralised Blasting System supports both the safety of the mine employees during blasting and an increase in production time.

This underground nickel mine in the Midwest United States is relatively young with only a few years of production blasting. The operation is employing a sublevel stope mining technique. The operator purchases Dyno TITAN® RU emulsion and electronic detonators for blasting. The customer was experiencing poor blast results over a substantial period of time. When the customer first contacted DynoConsult® for assistance, the concern was the under-breaking of the ore which left valuable material along the ribs. At that time the mine engineers were looking for guidance on the delay times they should be using to improve the recovery of ore. During the site visit by DynoConsult, it was also discovered that there were a few instances of benches and bridges being left in the stope after mucking. In one stope it was estimated that over $1 million worth of ore was left unrecoverable in the stope. It was also revealed during the site visit that there were issues related to tight digging of the muckpile even though the fragmentation was adequate.
