YT27 Rock Drills: Pre-Use ProtocolsWhat is a Pneumatic Rock Drill?
2. Conduct thorough inspections by tapping on the roof near the working face. This ensures your environment is free of hazardous loose or live rocks, taking necessary measures for stabilization.
3. The preparation of the working surface, specifically the shell hole location, must be perfectly flattened prior to drilling. This is crucial to prevent any occurrences of slippage or shell hole displacement during operations.
4. Under no circumstances should dry drilling be conducted. Uphold the practice of wet rock drilling: initiate with water flow, then proceed with air. Upon completion, cease the air flow first, followed by water. Begin your drilling at a reduced speed and transition to full speed only after reaching a certain depth.
5. Drillers must refrain from wearing gloves during operation to ensure maximum control and safety.
6. While utilizing the air leg for drilling, maintain a vigilant focus on your stance and positioning. Avoid exerting pressure with the body and never stand directly in front of the working brazing rod to avert injuries from potential breakage.
7. Should you encounter any unusual noises or unexpected water discharges during drilling, halt the operation immediately, conduct a thorough inspection to diagnose and rectify the issue before resuming.
8. When retracting the rock drill or substituting the brazing rod, operate the drill at a slow pace and remain attentive to the precise positioning of the rock drill braze.
