YT27 rock drills before use:What is a pneumatic rock drill?
2. Perform a safety check on the roof adjacent to the working face. This involves detecting and addressing any live or loose rocks on the roof and secondary face, thereby ensuring a secure drilling environment.
3. The drilling surface at the flat shell hole location must be prepped by leveling it beforehand. This precaution is critical to prevent slippage or misalignment of the shell hole during rock drilling.
4. Adhere strictly to wet rock drilling practices, avoiding dry drilling. Begin by initiating water flow prior to air pressure application, and cessation should follow the reverse order. Commence drilling at low speed initially, transitioning to full speed only after achieving adequate depth.
5. To ensure safety, drillers must not wear gloves while operating the drill.
6. When utilizing the air leg for drilling, maintain an appropriate stance and position. Avoid using body weight for pressure application and never stand in front of the rock drill when the brazing rod is in use, to prevent injury from possible rod breakage.
7. Should any abnormal noises or unexpected water discharges occur during drilling, halt operations immediately. Conduct a thorough inspection to identify and rectify the issue before resuming drilling activities.
8. During rock drill withdrawal or when changing the brazing rod, operate the drill at a slow pace and remain vigilant regarding the position of the brazing rod for safe and efficient handling.
