The role of exploration in the mining and resources industry

Mining excavators are important tools in the excavation industry, significantly impacting the efficiency and effectiveness of mining operations. This blog delves into the various techniques that enhance the capabilities of these powerful machines, providing insights on how to maximise their potential in mining applications. From understanding the basics of operation to maintaining optimal performance, we cover all the essential aspects to ensure you can use mining excavator digging techniques to their fullest.

Understand the basics of mining excavator digging

Mining excavators combine technology with precision. The key to effective excavation techniques is understanding machine mechanics and capabilities. This includes knowing how electric motors and hydraulic systems work, the importance of the excavator’s weight and balance, and how these elements affect digging efficiency and safety. Understanding these basics is crucial for any operator looking to enhance their skill set and improve productivity.

Choose the right mining excavators for the job

Selecting the right excavator is essential for efficient mining operations. The choice depends on the project's scale, the material to be excavated, and the conditions of the mining site. Here are some of the best mining excavators known for their reliability and performance in various conditions:

• Caterpillar 6090 FS: Known for its high productivity and strength.
• Hitachi EX8000-6: Offers one of the best force-to-weight ratios in its class.
• Komatsu PC8000-6: Features advanced technological systems for improved efficiency and safety.
• Liebherr R 996 B: Renowned for its exceptional power and reliability in harsh environments.

Optimise bucket positioning and angle

Optimal bucket positioning and the correct bucket angle are crucial for maximising the digging efficiency of mining excavators, especially when dealing with hard materials like rock or coal. Proper positioning helps reduce wear and tear while enhancing the digging force, leading to more productive operations. Steps to optimise bucket positioning and angle are as follows:

1. Adjust the bucket angle: Keep the bucket angle optimal to ensure maximum penetration and reduce spillage. An optimal angle also helps minimise the stress on the excavator's arm.
2. Position for power: Position the excavator for stability and power distribution, ensuring that the machine's weight supports the digging action without undue stress on any component. This alignment maximises the digging force and enhances fuel efficiency.
3. Depth control: Use depth control systems to maintain consistent digging depth, which prevents over-digging and enhances efficiency.
4. Real-time monitoring: Implement real-time monitoring systems to adjust the bucket position dynamically according to the soil condition and digging requirements.

Use advanced digging strategies

Advanced digging strategies can significantly improve the efficiency of mining operations. Incorporating these techniques ensures that excavators operate at peak efficiency, reducing operational costs and increasing productivity:

• Layer digging technique: This involves removing material in layers to maintain balance and enhance efficiency. It's particularly effective in managing the stability of the excavation site.
• Trenching method: Ideal for pipeline laying, this method involves precise digging to ensure straight and uniform trenches. It significantly reduces the need for additional grading and finishing.
• Sequential digging: This strategy uses a systematic excavation approach, optimising the movement and reducing the time spent repositioning the excavator.
• Cross-sectioning: Apply a cross-sectioning method to cut through various soil layers, which helps understand the different material types and choose the right tool for each layer.
• Selective digging: GPS and other guidance systems are used to perform selective digging, which targets specific areas for excavation and preserves the surrounding environment.

Maintain and upkeep excavator digging equipment

Proper maintenance of excavator digging equipment is essential for prolonged efficiency and safety. Regular upkeep also prevents costly downtime and extends the lifespan of the machinery. The key to maintaining your digging equipment includes:

• Regular inspections: Conduct daily inspections to identify and fix leaks, worn-out parts, and hydraulic system integrity. This proactive approach helps in avoiding larger issues down the line.
• Scheduled maintenance: Follow the manufacturer’s schedule to replace parts like filters, oils, and hydraulic fluids. Adhering to a strict maintenance schedule ensures optimal performance.
• Operator training: Ensure operators are trained on the latest maintenance procedures and safety protocols. Well-trained operators can significantly reduce the risk of accidents and machinery breakdown.
• Lubrication management: Regularly check and manage the lubrication of all moving parts to reduce friction and wear, enhancing the overall efficiency of the excavator.
