YT27 Rock Drills: Essential Pre-Use GuidelinesUnderstanding the Pneumatic Rock Drill
2. Conduct a thorough check of the roof near the work area by tapping to detect any unstable or loose rocks, especially on the roof and second gang near the working face. Undertake necessary measures to secure the area before proceeding.
3. Prepare the work surface meticulously by flattening the location of the shell hole before commencing rock drilling. This preemptive measure ensures that the shell hole remains stable, preventing any slippage or displacement.
4. Strictly adhere to wet rock drilling protocols by avoiding dry drilling. Always start with the water flow followed by the air when operating, and reverse the order when stopping. Begin drilling at low speed until a certain depth is reached, then transition to full speed.
5. For safety, drillers must refrain from wearing gloves while operating the drill.
6. While using the air leg for hole drilling, maintain proper standing posture and avoid using body weight for pressure. Never position yourself in front of the rock drill when working with the brazing rod to prevent injury from potential rod failure.
7. If unusual sounds or irregular water discharge are observed during drilling, immediately cease operations to investigate and resolve the issue before resuming work.
8. During the extraction of the rock drill or when changing the brazing rod, ensure the rock drill operates at a slow pace and carefully monitor the positioning of the brazing rod.
