2. Conduct a thorough inspection of the roof near the working face. Identify any loose or live rocks and secure them to ensure safety during operations.
3. Prepare the working surface by leveling the flat shell hole area in advance. This precaution prevents slippage and ensures precise drilling without misalignment.
4. Always prioritize wet rock drilling. Initiate drilling with water flow before air pressure, and cease air pressure before stopping water. Begin at a low speed, increasing to maximum drilling speed only after reaching adequate depth.
5. Drill operators must refrain from wearing gloves to maintain control and safety during operation.
6. While utilizing the air leg, adopt a proper standing posture without body pressure. Avoid standing in front of the drill to prevent injury from potential brazing rod fractures.
7. If you detect unusual sounds or water discharge during drilling, halt the operation immediately. Investigate and resolve the issue before resuming to ensure uninterrupted performance and safety.
8. When retracting the rock drill or changing the brazing rod, operate the drill slowly and remain vigilant about the positioning of the brazing rod for optimal safety and efficacy.
