Jackleg Drills in Underground Mining: Challenges and Solutions | GME

Introduction to Jackleg Drills in Underground Mining 

Jackleg drills also called pneumatic rock drills that are frequently used to drill blast holes in hard rock during underground mining. Their mobility and capacity to function in confined locations make them highly prized. Because of their simplicity and efficiency, they are still frequently utilized in minor mines and development headings even though they are older technology.

Common Challenges Faced with Jackleg Drills

Operators often face issues such as high physical strain, vibration exposure, and fatigue due to the manual nature of jackleg drilling. Other challenges include frequent maintenance needs, poor dust control, noise exposure, and reduced efficiency in hard or deep rock formations.

Ergonomic and Safety Concerns

Jackleg drills can lead to musculoskeletal injuries due to awkward body positions, heavy handling, and repetitive motion. Vibration exposure may cause hand-arm vibration syndrome (HAVS), while poor footing or control can result in slips or impact injuries. Ensuring proper ergonomics and safety protocols is essential.

Maintenance and Equipment Downtime

Frequent use in harsh underground conditions leads to wear on parts like pistons, valves, and drill steels. Inadequate or delayed maintenance can result in breakdowns, reducing productivity and increasing costs. Regular inspections, proper lubrication, and timely repairs are key to minimizing downtime.

Power and Efficiency Limitations

Jackleg drills have limited power compared to larger mechanized equipment, making them less effective in very hard or deep rock formations. Their manual operation can slow progress, especially in large-scale projects, impacting overall mining efficiency and increasing labor demands.

Solutions and Best Practices for Operators

Operators can improve efficiency and reduce fatigue by using proper drilling techniques, maintaining good posture, and taking regular breaks. Using well-maintained equipment, wearing vibration-reducing gloves, and following safety guidelines also help enhance performance and minimize health risks.
