YT27 rock drills before use:What is a pneumatic rock drill?
2. Conduct a thorough inspection of the roof near the working face. Confirm the absence of live or loose rocks on the roof and second gang, taking necessary corrective measures if any are detected.
3. The rock drilling process demands a pre-flattened working surface at the shell hole location to avert any potential slippage or displacement of the shell hole.
4. Emphasizing safety, drilling dry eyes is strictly prohibited. Always adhere to wet drilling protocols by activating water flow before air when operating, and disable the air before the water when ceasing operations. Commence with a low-speed drill when opening the hole, transitioning to full speed upon reaching a requisite depth.
5. Safety regulations dictate that drillers must refrain from wearing gloves during the drilling procedure.
6. While employing the air leg for hole drilling, maintain an appropriate standing posture and position. Avoid applying pressure with your body or standing directly in front of the rock drill under the work brazing rod to prevent injury from potential brazing fractures.
7. Should any unusual sounds or irregular water discharges be detected during drilling, promptly halt operations for inspection. Diagnose and resolve the issue before resuming drilling activities.
8. When retracting the rock drill or swapping out the brazing rod, allow for a slow operation of the drill. Remain vigilant to the positioning of the rock drill braze to ensure safety.
