Risk management enables the mining operators to address the most burning tasks of operational decisions and define the fundamental aspects of corporate culture, such as safety and equipment maintenance. As productivity depends on a smooth usage of equipment, resources and workforce, everything that happens unplanned may disrupt the complex choreography of mining processes. Risk management is best supported by solid data from the field - monitoring the conditions of machines, the site and the workforce in real-time.

The mining industry has always been risky, with worker safety concerns representing only a portion of the challenges. Increasingly strict regulations, reliance on technology, inconsistent demand for raw materials and high commodity prices are matters of high importance for a mining company. Fortunately, most mining corporations can offset this with effective risk management programs. Moreover, many industry executives are already ahead in effectively managing risks. They understand that significant gains often come with considerable risks, and well-designed programs enable them to pursue those opportunities safely.
Some of the top risks in the mining business include:
A risk management program allows mining companies to ensure the success of their operations. The key lies in understanding all the risks before committing to any specific project. For example, one of the leading concerns is a skills shortage. A significant portion of miners are retiring, and there isn't an influx of talented workers to substitute them, especially in remote regions. This can lead to project delays, higher labour costs and other production impacts such as reduced risk awareness. Another key risk is 'resource nationalism'. Countries are starting to acknowledge the value of the raw materials that originate from their land and, as such, are beginning to set higher taxes on foreign mining companies. This can increase the cost of operations significantly.
Besides external risk factors, which are impossible or hard to influence, cost and productivity are the fundamental elements determining an outfit's success. Excellent equipment and skills, favourable ore conditions and outstanding safety culture influence cost and productivity most and make risk management of these factors mandatory.
Favourable ore conditions
The ore conditions—the size, shape, and orientation of the ore body, as well as the grade of mineralization, the strength of rock materials, and even the depths you are working with—will all directly affect which mining method you utilize. The ore conditions will also affect how much your project will ultimately cost. High-grade ore is what every mine operator strives for. Still, when discontinuities accompany that high-grade ore body in the seam, variabilities in the seam with inclusions of waste rock or slips requiring mechanical supports, the costs per ton can escalate. The better exploration, the better you can assess the ore quality risk.
Everyone in the world of mining knows there is a dreaded word: downtime. When operations slow due to equipment failure (or, in a worst-case scenario, halt altogether), productivity suffers, and profits plummet. Risk management of equipment failure means moving away from reactive approaches to maintenance and heading toward preventive—and predictive—maintenance. The preventative approach does just as its name suggests. You can reduce downtime by regularly inspecting equipment to catch any minor problems and immediately fixing them before any more significant issues have time to develop. Ideally, a company's equipment will move from one planned service to the next without experiencing severe equipment or system failures, thus reducing costs and keeping productivity at its peak.
Consumables cost and availability
Ensuring you have the necessary parts and "ingredients" to keep your operations running is essential, regardless of how prices ebb and flow. For this reason, proper and intelligent management of your commodities is vital. This could mean keeping a certain amount of spare parts in stock. But, as with everything, stockpiling too many will result in tying up the necessary capital. Appropriate risk management manages an accurate stockpile of your necessities.
Labour costs and availability
Very similar to consumables, labour costs and availability must be considered. Much depends on the ability to procure and retain a well-trained staff, who can ensure a consistent flow of good work organization and help to maintain a high level of mining process mechanization—all of which optimize productivity and reduce underground facilities' overall costs. Risk management includes foremost safety and health conditions, hazard evaluation and risk analysis.
As we now understand the main drivers of costs and the need to manage them from a long-term perspective, let's dive into the domain of productivity.
Hard Fact Copper Production Worldwide: in 2020, global production increased in 1.36% to 20.7 Mio tons. Copper is one of the most important minerals to enable the green energy transition.
In general, productivity means higher output with the same amount of input. For example, productivity in the mining industry means the following:
There are many ways to increase productivity along these four general aspects of mining operations. Let's pick (deliberately) two of them: personnel and equipment. Optimizing available hours and assets helps work more efficiently, protects profits, and gives your business a cutting edge over the competition.
Manage Your Equipment
Manage your tools and equipment to keep operating smoothly and avoid expensive repairs, replacements, and unexpected downtime. The best way to do this is to establish an equipment management plan that accounts for every machine's needs, like regular servicing, preventive maintenance, troubleshooting, and fuel consumption.
Include the following in your equipment management plan:
A strong team
Your crew plays the most prominent role in your mine's productivity. You can create a strong team by setting up a program covering the following aspects:
As labour is the most critical asset of your operation, you don't want to sit them idle; you don't want to pay them for waiting. On the other hand, you don't want to run low on the workforce and don't want to pay high insurance, penalties or compensations for safety-related issues either. There is one answer: Run a safe mining operation. Productivity depends on your team, and a strong team needs to be safe.
The most recommended, industry-wide approach to safety in general, but mining in particular, is to take a 1-2-3 risk management approach. The top priority in risk management is always to eliminate risks as much as possible. The first level eliminates the hazard and the associated risk and is the most effective measure of control (e.g., no holes in the floor where people work). If this is not reasonably practicable, risks should be mitigated by substituting the hazard with something safer (install guard rails). The third level acts as an administrative control to minimize exposure to a threat (warning signs or protective equipment).
Following the three levels of risk management, an efficient safety approach could be established to mitigate the risks at all three stages:
Level 1 - Avoiding hazards at all: Close off areas and control site access, using, for example, electronic tags that act as keys to mines in general, but also to certain areas (e.g., explosives' storage)
Level 2 - Safeguarding against hazards: Reporting the safe zone position of every worker underground or above ground in case of a scheduled blast (learn more about RFID in mining).
Level 3 - Warning of hazards: Personal tags indicate the current positions and the route to safety in an emergency (read on about personnel tracking in mines).
These examples show that the safety, risk management and continuous operation of a mine are aligned. Efficient operations require visibility (workers and machinery) and preparation for an emergency. In general, a scheduled blast won't disrupt ongoing mine operations too long but will integrate efficiently into the daily work procedures.
Risk management enables the operations directors to address the most burning tasks of operational decisions and define the fundamental aspects of corporate culture, such as safety and equipment maintenance. Productivity depends on a smooth usage of mining technology, resources and workforce and everything that happens unplanned may disrupt the complex choreography of mining processes, resulting in lower mine productivity. Risk management is best supported by solid data from the field - monitoring the conditions of machines, the site and the workforce in real-time.
