Geotechnical Risks: Sinkhole Formation & Subsidence in Mining Activities

Sinkholes—depressions or voids that suddenly form when materials beneath the ground fail—represent one of the main risks associated with underground mining. These geotechnical impacts can severely affect infrastructure, agriculture, and communities near large-scale mining operations, especially in geologically sensitive regions.

How Sinkholes Develop in Mining Contexts

Subsurface Excavation: Removing volumes of ore or coal creates underground cavities—if left unsupported, these may collapse, forming sinkholes at the surface.
Groundwater Imbalance: Changes in groundwater flow due to mining activity can weaken strata, further increasing subsidence and sinkhole potential.
Material Properties: Certain geological conditions, notably those containing soluble limestone or unstable clays, are particularly prone to sinkhole formation after heavy excavation.
Surface Disturbances: Vibration from drilling, heavy machinery, and blasting can accelerate destabilization in weakened bedrock.

To counter these issues, mining companies must combine vigilant planning with smart, real-time hazard detection—including the use of satellite imagery, AI-driven geotechnical modelling, and automated surveillance to detect early signs of subsidence.

Does Extraction from Coal Mines Make Sinkholes? Contrasting Copper Ore Mining and Coal

It’s vital to differentiate between sinkholes caused by copper ore extraction and those resulting from coal mines. This distinction is crucial for accurate geotechnical risk management and environmental impact assessment in mining regions.

Sinkholes in Coal Mining

Longwall coal mining is notorious for triggering sinkholes—large, contiguous blocks of coal are systematically removed, creating immense underground voids. Over time, shifts in overlying strata and ground collapse can inevitably form sinkholes.
Underground coal extraction in older regions, such as the US Appalachians, parts of China, and the UK, remains a chief contributor to persistent subsidence and infrastructure damage.

Copper Ore Mining and Sinkhole Risk

Open-pit copper mines (surface methods) generally pose less risk for sinkhole formation, as large excavation happens closer to the surface and voids are often backfilled or stabilized.
However, underground copper mining using block caving or sub-level stoping can create voids similar to coal extraction, especially if ground control and geotechnical monitoring are inadequate.
Modern copper mining operations (2025 and beyond) use advanced risk modeling and stabilization techniques—such as systematic backfilling, strategic pillar design, and AI-driven prediction—to mitigate surface collapse.

Modern Approaches to Risk Mitigation: Integrated Monitoring, AI, and Real-Time Systems

Addressing sinkhole formation and subsidence in copper extraction from ore requires a robust, proactive approach. Mining companies in 2025 employ a suite of integrated technologies to anticipate and reduce risks, protecting both operational areas and neighboring land.
