Ultra-class isn't always the answer; right-sized payloads win. The selection of either ultra-class (payload 360–400 tons) or large-class (payload 180–240 tons) of haul trucks is an important financial decision in terms of open-pit surface mining operations. An investment in a single 400-ton haul truck is multi-million dollar in nature, and operation cost during the lifetime of 15 to 20 years can be more than $40 million for a single truck. Though a higher payload will reduce cost per ton in transportation, but these benefits are subject to geological structure, pit road size, and loading shovel suitability. How to evaluate the payload and productivity trade-offs between ultra-class and large-class haul trucks for your pit? Share your thoughts in comments.

Loaders win on mobility, but shovels win on narrow-bench productivity. A wheel loader is an extremely mobile machine fitted with tires whose job is scooping up loose materials by virtue of a continuous drive-in loading process. On the other hand, a hydraulic face shovel is a heavy machine that uses hydraulic mechanisms in digging upward from the pit floor to the face. Narrow pit bench is a term referring to a very restricted mining environment where there is little room for manoeuvring large machinery. What are the engineering parameters used to evaluate the productivity of a wheel loader versus a hydraulic face shovel for loading in a narrow pit bench? Share your thoughts in comments.

Design haul roads and wearing courses that cut rolling resistance and vehicle damage. A “geotechnical analysis” of haul roads in a mining site is defined as the comprehensive analysis of the subgrade and structural components to determine their suitability to carry extra-heavy load of trucks over an extended period. On the other hand, “wear course” denotes the top most layer of the pavement which contacts with the truck wheels to provide friction, draining and abrasion resistance. “Rolling Resistance” is defined as the drag force produced due to contact between the wheel and pavement surface which must be overcome during movement of vehicle. How to conduct a haul road geotechnical assessment and specify a wearing course design that minimises rolling resistance and vehicle damage? Share your thoughts in comments.

Bigger fleets don't beat rising strip ratios, but smarter scheduling does. Open-pit mines face a series of economical and practical problems when mining pits become deeper over various developmental stages. Rising strip ratio means that significantly more overburden material should be moved along with the ore. Deeper ramps mean greater time needed for hauling. The standard solution of merely adding new haul trucks is not effective enough. Extra trucks result in extra traffic jams on ramps, waiting at the shovels' loading sites, as well as increased maintenance costs. Effective scheduling of the fleet needs mathematics and engineering solutions. What's the correct approach to scheduling equipment fleet size against a rising strip ratio in later pit stages?

Remote LHDs in seismic stopes: the engineering limits of teleoperation. The Load-Haul-Dump (LHD) equipment consists of a center-articulating vehicle with a bucket at its front end and is used exclusively for the excavation, transportation, and dumping of ore within underground mines. Seismogenic stoping extraction conditions entail deep, highly stressed geological regions that undergo constant rock removal and experience seismic activity because of mining activities like rockbursts. What are the engineering requirements for remote-controlled operation of underground LHDs in a seismically active stope extraction environment? Share your thoughts in comments.

Optimization algorithms define the optimal pit shell, maximizing mining profit. Optimization algorithms are fundamental to strategic mine planning, primarily used to define the Ultimate Pit Limit (UPL); the boundary that maximizes the total economic value of an open-pit mine (Esmaeil et al., 2018; Xu et al., 2024). These algorithms process a three-dimensional block model where each discrete block contains geological and economic data, such as ore grade, density, and extraction costs (Ares et al., 2022). What role do optimization algorithms (e.g., LerchsGrossmann, floating cone) play in determining the optimal pit shell? Share your thoughts in comments.

Designing an underground mine decline? Here are the key considerations. A decline in an underground mine should be designed around geometric, geotechnical, operational, and economic constraints so that it is safe, practical, and cost-effective over the mine life (Brazil et al., 2008). In practice, the best decline design balances truck access, rock stability, ventilation, and haulage efficiency from the start (Brazil et al., 2008).

Design and maintain haul roads to cut rolling resistance and cycle times. Haul roads are engineered in a way such that their surface remains stiff, properly drained, and geometrical smooth to minimize the energy spent in fighting the rolling resistance and the time taken for braking and making repairs. It has been proven that the road gradient remains constant due to the geometries of the mine, while the rolling resistance is variable.

Weak rock, steep slopes: what really governs safe pit design? Slope stability analysis in open-pit mining considers the slope geometry at different scales such as benches, inter-ramps, and the entire slope. Inter-ramp angle refers to the angle between two consecutive ramps, and it is computed based on the toe-to-toe line between two ramps. Overall slope angle (OSA) refers to the macro-scale inclination measured from the crest point down to the toe of the slope (Agosti et al., 2021). In open-pit mining, excavation of weak and altered rock masses poses significant geotechnical challenges for the engineers involved in slope stability assessment. What are the geotechnical design criteria for open-pit inter-ramp and overall slope angles in weak, altered rock masses? Share your ideas in comments.

Ore grade drops: dilution or design? Diagnose before you blame. The sublevel open stoping technique is the main underground mining method adopted for the mining of ore deposits with steep dip, but unanticipated dilution of the ore is a great economic challenge in mining projects. The accidental blending of waste rock continuously reduces the ore grade raised from the underground, leading to greater costs in mucking, hauling, and processing operations, reducing the net present value of the mine assets. How to diagnose the cause of excessive dilution in a sublevel stoping operation? Share your ideas in comments.

Design pre-split right; blast damage wrecks wall stability. As open pit mines grow deeper, it becomes necessary to have more inclined slopes to ensure profitability and avoid excessive wastage of material. However, steep highwalls increase the geotechnical hazards, such as slope instability, crest destruction, and accidental rock falls (Tasoren et al., 2016). Pre-splitting blasting is a technique used to protect the final pit walls from deterioration due to blasting operations. How to optimize a pre-split blast design to improve final wall stability in a deep open pit? Share your thoughts in comments.

Faults offset orebodies; cross-sections restore truth, not guesswork. Fault-related displacements present major technical problems in mining geology. One single faulting event may break apart an otherwise contiguous body of highly valuable ore deposits over large distances (Peters, 2001). Mining prospectors usually fail to make accurate interpretations of the underground geology due to their reliance on simplified two-dimensional flat maps. Proper interpretation of faulted mineral deposits requires careful three-dimensional spatial analysis and structure validation. What's the correct method for constructing a structural cross-section through a faulted, offset orebody? Share your ideas in comments.

Real EM targets signal; cultural noise just interferes. Exploration for minerals in brownfields requires mining near large industrial infrastructure. High-voltage transmission lines, pipelines, and metallic fencing lead to electromagnetic interference, which masks weak subsurface signals (Beauvais, 2026; Rodriguez et al., 2006). Simulation models have found that the current from power lines causes high-amplitude signals that simulate geological fault zones or conductive minerals (Beauvais, 2026). How do you distinguish a real EM anomaly from cultural noise (fences, pipelines, power lines) in a brownfields survey? Share your thoughts in comments.

Uranium's comeback: the force powering a nuclear energy renaissance. The uranium spot and contract price has witnessed a significant revival during the last ten years, growing four times from historical lows with nuclear power once again making its way into the mainstream energy policy of the world. This reflects a structural change within the full nuclear fuel cycle instead of just a price rise in a commodity. There are three key structural drivers of such a market shift: decarbonisation needs of countries within the climate context, the electricity needs of artificial intelligence data centers, and geopolitical shifts with an eye on protecting the nuclear fuel chain. What's driving the resurgence of interest in uranium mining and processing capacity? Share your thoughts in comments.
