YT27 rock drills before use:What is a pneumatic rock drill?
2. Conduct a thorough assessment by tapping the roof near the working face. Examine for any loose or live rocks on the roof or the second gang adjacent to the working area, and perform necessary stabilization measures.
3. Prepare the drilling surface by leveling the flat shell hole location in advance. This precaution prevents slippage or misalignment during the rock drilling process.
4. To prioritize safety and efficiency, avoid dry drilling. Always conduct wet rock drilling by activating the water supply first, followed by the air. Upon completion, cease air flow before shutting off the water. When starting, initiate at a low speed, advancing to full speed only after reaching sufficient depth.
5. For safety reasons, drill operators must refrain from wearing gloves during operations.
6. When employing the air leg for drilling, maintain proper posture and positioning. Avoid applying pressure with your body and never stand in front of the rock drill while the brazing rod is in use, to prevent injury from potential breakage.
7. If any unusual noises or irregular water discharge occurs during drilling, immediately halt operations for inspection. Diagnose and resolve any issues before proceeding with drilling activities.
8. When retracting the rock drill or changing the brazing rod, allow the drill to operate at a slow pace, carefully monitoring the position of the rock drill braze to ensure safety.
