Roof bolting in underground mining can be automated and operated remotely, greatly improving both safety and efficiency. Automated roof bolting systems have been developed to carry out the full bolting process including drilling, removing drill steel, placing resin, and installing bolts without manual input. These systems utilize robotic arms guided by programmed motion sequences to handle intricate tasks, minimizing the need for workers to be exposed to dangerous areas near the mine roof(Design Criteria And Guidelines For Falling Object Protective Structures (FOPS), n.d.).
Advancements in human-machine interfaces (HMI) now enable operators to remotely control roof bolting machines from safer locations, reducing exposure to hazards. These systems also use 3D modeling and optimized robotic paths to ensure precise and repeatable operations in tight underground spaces, as demonstrated in lab testing.
Recent studies emphasize the integration of advanced robotic systems, such as six-axis arms, into roof bolters to reduce operator fatigue, improve precision, and enhance safety. These systems use environmental perception to adapt tasks like drilling and bolt placement, ensuring cleaner, more accurate work. Remote capabilities also handle functions like bit and rod changes, minimizing exposure to dust and mechanical hazards. Overall, automated roof bolting is emerging as a crucial technology for reducing injuries and boosting underground mining efficiency(Court, 2021).
