Here's a clear comparison to explain why:
🔒 Safety Advantages of Rock Drilling Machines
1. Reduced Direct Exposure
Operators work inside a protected cabin or at a safe distance
Less exposure to falling rocks, collapses, and blasting hazards
2. Stable and Controlled Drilling
Mechanical feed beams and hydraulic control ensure stable drilling angles and depth
Avoids risks caused by manual misalignment or unstable footing
3. Lower Labor Intensity
Replaces manual hammer drilling and hand-held tools
Reduces fatigue-related accidents, which are common in artificial construction
4. Better Performance in Poor Geology
Effective in broken surrounding rock, soft rock, or high-risk zones
Faster support installation (bolts, anchors), reducing exposure time
5. Improved Working Environment
Less vibration transmitted to workers
Can be equipped with dust suppression, noise reduction, and lighting systems
⚠️ Risks in Artificial (Manual) Construction
Workers stand directly under unsupported rock
High risk of rock fall, tool kickback, and slips
Slower progress means longer time in dangerous zones
Inconsistent drilling quality affects bolt and support reliability
📌 Practical Conclusion
For modern tunnel and slope projects:
Rock drilling machines = higher safety + higher efficiency + better quality
Manual construction should only be used in very small spaces or special cases
This is why most modern tunnel standards and owners require mechanized drilling instead of artificial construction.
