Fuel burns money. Track it, manage it, and reduce it. In most cases, fuel consumption monitoring of big mining mobile equipment takes place using a telemetry-based fuel management solution. That means that all relevant information (live fuel rate, amount of fuel consumed, engine hours, idle times, operating modes) is sent from each piece of mining equipment directly to the centralized control center where it allows managers to see how every truck, loader, excavator, and any other vehicle perform its tasks. It is worth noting that some telemetry systems utilize direct fuel flow meters mounted in the fuel line. They are more accurate and less prone to errors caused by vehicle vibrations, slope, etc. Does operator behavior reduce fuel more than fleet automation does? Share your thoughts in comments!

Sensors predict failures. Algorithms schedule maintenance before breakdowns happen. Machine learning is currently being utilized for predictive maintenance in mining through conversion of data streams from sensors and maintenance logs to early alerts regarding failure modes, which allows personnel to act before a failure occurs. This process essentially changes the maintenance strategy from time-based or corrective actions based on failures to proactive decisions based on the real-time condition of the asset.

Accelerate for cash now, or extend for value later? Although increasing production rates will help in improving the short-term financial flows, this is typically going to require even more money both in terms of capital investment and operating expenditures to enable the mine to work at such rates. These may include such expenses as upgrading mills, buying more trucks and load-haul dumps, employing more staff, increasing energy and water consumption, among others. However, on the one hand, a mine would produce revenues earlier and more intensively than before, but, on the other hand, there could be increases in unit costs since the capacity of existing infrastructures or ore deposits is exceeded.

AISC tracks real gold mining costs, not just production expenses. The all-in sustaining cost, abbreviated as AISC, is a cost metric used for the gold mining industry. It provides insight into the total costs required to produce an ounce of gold while maintaining ongoing operations. This measure was developed by the World Gold Council in 2013 in order to provide greater comparability in gold cost reporting and a more comprehensive alternative to cash costs reporting. Does AISC truly reflect profitability, or does it hide exploration costs? Share your thoughts in comments!

CAPEX builds the mine. OPEX keeps it running daily. When it comes to the economics of mining, it is extremely difficult, if not impossible, to describe the industry without addressing two key concepts: capital expenditure (CAPEX) and operating expenditure (OPEX). These two terms form the basis of mining economics and provide an understanding of how mining projects are financed. In the mining industry, CAPEX refers to expenditure that will be incurred when acquiring/building/materially improving assets used in production in the future, whereas OPEX refers to the cost involved in running the mining activities in the short term. CAPEX will include expenditures like purchasing mobile equipment, developing the mine, building the plant, constructing the tailings area, building roads, etc., while OPEX will involve costs like fuel, power generation, consumables, labor, tires, contractor fees, spare parts, etc. Does high CAPEX automation reduce OPEX enough to justify the cost?

Simulation reveals bottlenecks before they destroy your production schedule. Simulation models enable mining engineers to consider various designs, plans, and operational assumptions without spending capital resources, thereby decreasing the probability of designing a mine plan which will not work practically. Moreover, simulation models play an important role in strategic mine planning by considering alternative scenarios regarding mine pit slope, scheduling, production scale, fleet size, and extraction level, as well as by identifying the impact of such alternatives on value, risk, and mine life.

Paste backfill must flow, stand, and support without failing. The backfill engineering of open stopes with CPB revolves around the stability, pressure, drainage, and curing processes that allow for the development of CPB that can sustain itself and neighbouring mining operations. Studies performed in the field and in models have revealed that CPB behavior is greatly influenced by many factors, including the geometry of the stope, the composition of the binder, the filling rate, barricades, and the subsequent stope wall closure process. Therefore, a universal solution to backfilling cannot be applied here. Does paste strength or pipeline flowability pose greater engineering difficulty? Share your thoughts in comments!

What are the key considerations in designing a blasting sequence and delay timing? Blasting sequence is the planned order in which explosive charges in a blast are detonated, while delay timing is the specific interval of time between sequential detonations. Together, they are critical for achieving finer rock fragmentation, controlling rock displacement, and minimizing ground vibrations by allowing seismic waves from each explosion to interfere constructively or destructively.

Skarns whisper value through garnet, pyroxene, and base metal anomalies. In the early stages of prospecting for economically viable skarn deposits, what is generally used as the indication of potential deposits is not an individual clue but the combination of several clues, namely intrusion geology, alteration features, pathfinder geochemistry, and geophysics. Since skarns tend to be zoned, the most productive method of prospecting would be to trace alterations distally and then follow the zoning closer to the intrusion-contact zone. Is alteration mineralogy or metal geochemistry the better skarn indicator? Share your thoughts in comments!

Primary, secondary, supergene; each type needs its own process. The primary stage of mineralization is an early stage of ore formation due to the rising of hot aqueous fluids deep underground and results in the formation of hypogene ore minerals. The secondary mineralization is a subsequent stage wherein the earlier formed ore minerals are subjected to alteration and redeposit by fluid circulation closer to the surface; this is often referred to as supergene mineralization or supergene enrichment. Does supergene enrichment help mining more than primary hardness hurts it? Share your thoughts in comments!

Mining builds nations. Without it, many developing economies would collapse. Mining sector’s direct contribution to the global gross domestic product is usually reported in low single digits or low double digits of global GDP, but its actual proportion is determined by whether the calculation only considers mining itself or mining in combination with other related sectors. One report in the mining industry claimed that the direct contribution of the global mining sector was around 6.9 percent of global GDP in 2019, and according to a World Bank report, the actual impact of mining on GDP is much higher if all related economic activities were considered.

What should be considered when designing a push-pull primary and secondary ventilation systems? The duty on mine ventilation shafts is usually either intake or exhaust; it is unusual to split the shaft vertically with one compartment an intake and the other an exhaust. Modern mines in Australia also rarely employ “push” or “push-pull” primary ventilation systems; they are almost always surface exhaust (“pull” or extracting) systems. Similarly, underground district (circuit) ventilation systems are almost always designed as exhaust-only. This paper describes an unusual set of circumstances that led to the selection of a conventionally sunk, concrete-lined, vertically-split primary ventilation shaft with asymmetrical intake and exhaust compartments for a major mine expansion in Indonesia. Site power generation costs are high, so to provide a ventilation-on-demand system to deliver intake air directly to the new working levels as required, an unusual push-pull district ventilation system was also utilized. The split shaft design was also required to facilitate retrofitting of surface refrigeration if the mining depth or level of activities required. A key issue was to ensure satisfactory safety including egress and entrapment design for underground workers. This paper describes the factors impacting on the choice of the ventilation design, the design itself and the management of the risks associated with the design, and the various implementation issues on the site.

Clay jams crushers, blinds screens, and chokes thickeners mercilessly. The presence of high clay in the ore results in difficulties in the operations process since the presence of clay in the ore causes changes in the rheological properties of the pulp, hinders particle settling, and affects fixed plant unit processes. This relationship between high clay ore and poor performance in some unit processes was observed at Chuquicamata. Do high-clay ores challenge crushing more or wet processing more?
