YT27 rock drills before use:What is a pneumatic rock drill?
2. Conduct a thorough inspection by tapping on the roof adjacent to the work area. This involves evaluating the presence of any loose or unstable rocks on the roof and the second gang near the workspace. Perform the necessary remediation to ensure stability and safety.
3. Prepare the working surface by ensuring it is leveled at the shell hole location well in advance of drilling activities. This precautionary measure is crucial to mitigate the risk of slippage or displacement of the shell hole.
4. Adhering to strict safety protocols, avoid dry drilling at all costs. Prioritize wet rock drilling, initiating water flow before air when operating. Conversely, cease air flow before water when halting operations. Begin with a low-speed approach when opening the hole, transitioning to full speed only after reaching a predetermined depth.
5. Under no circumstances should drillers wear gloves during drilling operations.
6. When utilizing the air leg for drilling, maintain an appropriate stance and position. Refrain from applying body pressure, and never position yourself directly in front of the rock drill or working brazing rod to avert potential injury from brazing breakage.
7. Should you encounter abnormal sounds or irregular water discharge during rock drilling, immediately cease operations. Undertake a thorough inspection to identify and rectify the issue before resuming the drilling process.
8. During the retraction of the rock drill or substitution of the brazing rod, allow the rock drill to operate at a reduced speed, remaining vigilant of the rock drill braze's position to ensure operational safety.
