Understanding the Different Types of Mining

The mining industry holds a vital role, not only as the source of metals and minerals but as a backbone for a wide range of sectors—construction, manufacturing, technology, and even pharmaceuticals all rely on its output. Beyond driving GDP growth for producing nations, mining spurs employment and regional development, while also prompting advancements in engineering and environmental science.

By providing essential raw materials like coal, iron ore, copper, and precious metals, mining sustains the infrastructure and operational needs of countless industries. From consumer electronics to automotive manufacturing and crucial construction materials, these sectors depend on the reliable supply of resources from mining, highlighting the industry’s extensive and significant impact.

The Four Mining Types
Mining is broadly categorised into two main types based on the extraction process: surface (above ground) and underground, each with its own engineering, environmental, and economic implications. These types can be further divided into distinct operations:

  1. Surface Mining: Extracts minerals near the surface by removing overburden. Techniques include strip mining, open-pit mining, mountaintop removal, and dredging.
  2. Underground Mining: Accesses deep ore deposits via tunnels or shafts. Methods include room and pillar, narrow vein stoping, and block caving.
  3. Placer Mining: Uses water to separate dense minerals like gold from sediment in placer deposits, often through panning.
  4. In-Situ Mining: Dissolves minerals in place for extraction, commonly used for uranium and potash.

In this article, we’ll be focusing on the big two, above and underground mining.

Above Ground Mining

Above ground mining, commonly known as surface mining, involves the removal of overburden—layers of soil and rock lying above the mineral deposits—to access valuable resources. This method is widely used to extract materials such as coal, iron ore, bauxite, copper, and limestone.

Surface mining is favoured for its high recovery rate and relatively lower production costs compared to underground techniques, making it especially suitable for large, shallow ore deposits.

Techniques and Processes Used

  1. Open Pit Mining:
    • Open pit mining, or open cut mining, is a large-scale excavation technique where a massive pit is created by removing overburden in a step-like manner. Miners work downwards, layer by layer, using heavy machinery to dig out ore while ensuring the stability of the pit walls. This method is ideal for near-surface, thick deposits and is commonly used for copper, iron ore, and gold. This form of mining is common in Western Australia.
  2. Strip Mining:
    • Strip mining is used to access horizontally distributed mineral layers close to the surface. This method involves removing strips of overburden to uncover ore, which is then extracted, and the process is repeated in adjacent strips. It’s widely used for coal mining in relatively flat areas and enables efficient removal of large quantities of material.
  3. Mountaintop Removal Mining:
    • Primarily used in coal mining, mountaintop removal involves blasting the tops of mountains to access underlying coal seams. This method reshapes landscapes, creating flat or rolling landforms post-mining, but is often controversial due to its environmental impact. It employs explosives, draglines, loaders, and haul trucks to extract coal in steep or mountainous regions.

Machinery and Equipment

Surface mining relies on heavy machinery, including crawler bucket excavators for digging, haul trucks for transporting materials, bulldozers and graders for levelling, and loaders for shifting extracted minerals. In some operations, blasting techniques are also used to break up rock layers more efficiently, often involving a series of boring machines to place explosives like ‘ANFO‘ (ammonium nitrate/fuel oil).

Each technique is carefully adapted to the specific mineral deposits, environmental conditions, and production demands, optimising the extraction process while addressing the safety and environmental challenges unique to surface mining.

Underground Mining

Underground mining entails the creation of subsurface tunnels (headings) and shafts to access deeply buried mineral deposits. This process is often more hazardous and costly compared to surface mining but is indispensable for extracting precious metals and minerals positioned deep beneath the earth’s surface.

Methods and Challenges of Underground Mining

Various methods are employed for underground mining, including:

  • Drilling, blasting, and mucking out – Often using underground tunnels, charges are placed above the material, and the blasted material falls to a lower tunnel for removal, a process known as “mucking out.”
  • Stoping (pronounced “stoap-ing”) – In stoping, miners dig out valuable ore from underground, leaving open spaces called “stopes.” These spaces can be left open or filled with stabilised materials (like waste rock or sand) to support the mine structure and prevent collapses.
  • Longwall mining – A cutting machine slices coal from a long wall, while an Armored Face Conveyor (AFC) moves the coal away. Hydraulic supports protect the roof as mining progresses, allowing controlled collapse behind the work area and enabling efficient and safe coal extraction.

Each of these methods describes only the excavation process. Transporting material for further processing involves using conveyors, elevators, or vehicles to manually load and move the material.

Challenges in underground mining include technical difficulties such as equipment breakdowns, high operational costs, and significant safety risks related to collapses and gas exposure, all of which demand rigorous safety protocols.

Underwater Mining Methods

Underwater mining methods, such as dredging and seafloor mining, are employed to extract resources like sand, gravel, diamonds, and polymetallic nodules from beneath bodies of water. Dredging typically involves suctioning sediment from the seabed, mainly in shallower areas, while deeper-water techniques use remotely operated vehicles (ROVs) equipped with cutting and suction tools to collect materials.

This specialised mining technology is designed to tackle challenges like high pressure, darkness, and cold temperatures, but must also carefully manage environmental impacts, such as sediment disturbance, to protect marine ecosystems. Underwater mining plays a critical role in providing minerals essential to industries like electronics and renewable energy.

Open Cast Mining to Underground Stoping Methods

Open cast mining to underground stoping methods employ techniques like sub-level stoping, room and pillar, and block caving, each tailored to specific geological conditions. Sub-level stoping involves controlled blasting within steep ore bodies; room and pillar leaves support pillars intact within flat deposits; and block caving allows ore to collapse naturally, facilitating cost-effective bulk mining. Each of these methods optimises resource extraction as mines transition from open-pit to underground operations.

The Role of Services and Maintenance in the Australian Mining Industry

    • Heavy machinery like excavators, haul trucks, and loaders experience constant exposure to abrasive materials, which wear down components like buckets, tyres, tracks, and hydraulics. This requires frequent replacement of high-wear parts and preventative maintenance.
    • To address this, maintenance teams often set up regular inspection schedules and use durable, wear-resistant materials to extend component life.
  2. Hydraulic System Failures:
    • Many mining machines rely on hydraulic systems to power their functions, but these systems can be prone to leaks, contamination, and wear. In mining, hydraulic systems are subject to high-pressure and dusty environments, increasing the risk of contamination.
    • Regular hydraulic fluid monitoring, filter changes, and sealing replacements are necessary to prevent unexpected failures and extend system life.
  3. Electrical and Electronic Malfunctions:
    • Mining vehicles and handling equipment rely on complex electrical systems for control, navigation, and communication. Dust, moisture, and vibration can cause issues with sensors, control panels, and wiring, leading to malfunctions.
    • Maintenance teams perform routine diagnostics and protective sealing on electrical components, and they often store spare parts for rapid replacement to minimise downtime.
  4. Structural Fatigue and Cracking:
    • Mining equipment frames and structures endure heavy loads and impact, which can lead to cracks and structural fatigue over time. Detecting structural damage early is crucial to prevent catastrophic failures.
    • Non-destructive testing (NDT) methods, like ultrasound and magnetic particle inspections, are commonly used to detect early signs of fatigue and cracking, allowing repairs before major issues arise.
  5. Conveyor Belt and Crusher Maintenance:
    • Conveyors, crushers, and hoppers are essential for transporting and processing materials. However, they are prone to issues like belt misalignment, mechanical wear, and material blockages.
    • Maintenance for conveyors includes belt alignment checks, roller inspections, and lubrication of moving parts. Crushers require frequent clearing of blockages and monitoring of wear on liners and jaw plates to ensure smooth processing.
  6. On-Site Repair Logistics:
    • Mining sites are often remote, making access to spare parts and skilled technicians a challenge. Many operations set up on-site repair workshops to manage minor repairs, while more complex repairs may require specialised equipment or off-site servicing.
    • Inventory management for spare parts is crucial, as is having skilled mechanics and technicians who can troubleshoot and fix issues on-site to reduce equipment downtime.

Safety measures in underground mining

Underground mining is a demanding and often high-risk occupation, involving harsh conditions, confined spaces, and proximity to heavy machinery. With the constant potential for hazards like toxic gas buildup, rockfalls, and equipment malfunctions, ensuring safety is paramount. Thanks to technological advancements and rigorous safety protocols, underground mining today is safer than ever. Here’s a look at some of the critical safety measures in place to protect workers in these challenging environments.

1. Ventilation Systems: Providing Clean and Safe Airflow

One of the primary concerns in underground mining is maintaining air quality. Toxic gases such as carbon monoxide, methane, and other contaminants can accumulate quickly, putting miners at serious risk. Modern ventilation systems play a vital role in ensuring that fresh air flows continuously throughout the mine, diluting and removing hazardous gases.

Many mines today are equipped with ventilation-on-demand (VOD) systems that adjust airflow based on the number of workers and equipment in specific sections of the mine. This dynamic ventilation approach not only improves air quality but also conserves energy, allowing mines to reduce operational costs while keeping workers safe. Additionally, continuous monitoring of air quality through sensors alerts workers immediately if there is an increase in harmful gas levels, enabling swift evacuations when necessary.

2. Structural Supports: Reinforcing Tunnels to Prevent Collapses

Mining involves creating extensive networks of tunnels and chambers within the earth, and without proper reinforcement, these structures are prone to collapses and rockfalls. Various structural support methods are employed to stabilise these spaces, ensuring that workers can move and work safely.

Commonly used structural support techniques include rock bolting, where long steel rods anchor layers of rock together, and shotcrete, a sprayed concrete coating that reinforces the tunnel walls. Some mines also use wire mesh and advanced monitoring systems that detect shifts or vibrations in the rock, which might indicate a weakening structure. With these supports in place, miners can work in stable, secure environments, reducing the likelihood of catastrophic incidents.

3. Gas Monitoring and Detection Systems: Staying Alert to Hidden Dangers

Underground mining environments can quickly become hazardous with the accumulation of invisible gases like methane, which is highly explosive, and carbon monoxide, which can cause suffocation. Continuous gas monitoring is essential to safeguard workers against these dangers.

Portable gas detectors and fixed monitoring systems are widely used in mining operations. Portable detectors allow workers to check gas levels in specific areas, while fixed systems monitor entire sections of the mine. When gas levels approach unsafe thresholds, these systems trigger alarms, alerting workers to potential risks and enabling rapid evacuation if needed. This proactive approach helps mitigate one of the most significant threats to underground mining safety.

4. Regular Safety Drills: Preparing for EmergenciesEven with robust safety measures, incidents can occur, making preparation essential. Regular safety drills are a cornerstone of mine safety protocols, helping miners respond effectively to emergencies like fires, gas leaks, and rockfalls. These drills equip workers with crucial knowledge about evacuation routes, safe zones, and emergency procedures.

Mines often conduct specific types of drills, such as self-rescue device training, where miners learn to use equipment that provides breathable air in hazardous conditions. Additional drills for fire response and first aid ensure that all personnel are prepared to handle emergencies efficiently. By practising these scenarios, miners gain the confidence and skills needed to act quickly, reducing risks to themselves and their colleagues.

Mining vehicles are essential for transporting materials and equipment, but in confined underground spaces, they can pose risks if not properly managed. The use of automated safety systems in vehicles has become increasingly common in modern mines, helping to prevent accidents and improve operational efficiency.

Collision detection sensors and lane-keeping assistance technology help drivers navigate narrow tunnels and avoid potential collisions with walls or other vehicles. Some mines have also implemented remote operation technology, allowing workers to control vehicles from a safe distance, especially in high-risk zones. Routine vehicle inspections ensure that brakes, lights, and other essential systems are functioning correctly, further enhancing safety.

6. Access Point Safety: Securing Shafts, Declines, and Ramps

Access points, such as shafts, declines, and ramps, are critical infrastructure components that facilitate safe entry, exit, and material transport within the mine. Regular structural integrity checks ensure these pathways remain stable and functional, preventing incidents that could arise from weakened structures or erosion.

In addition, safety protocols and training are essential for workers using these access points. Workers receive training on safe procedures for entering and exiting shafts and are equipped with knowledge about emergency escape routes. This structured approach ensures that access points are not only secure but also well-managed in emergencies.

7. Embracing Predictive Maintenance and Condition Monitoring

To enhance safety and efficiency, many mining companies have adopted predictive maintenance technologies. These systems use sensors and data analytics to monitor the condition of equipment and infrastructure continuously. By tracking metrics like vibration, temperature, and wear, predictive maintenance can identify potential issues before they become problems, reducing the risk of unexpected breakdowns.

This technology allows for more precise scheduling of repairs, minimising downtime and ensuring that equipment is always in optimal working condition. It also reduces the need for miners to be in high-risk areas for extended periods, as maintenance can be done proactively based on data-driven insights.
