2. Conduct a thorough inspection by tapping on the roof near the working area. This ensures there are no loose rocks or unstable formations that may pose a risk. Address any live rocks or loose stones on the roof and adjacent areas to maintain a safe working environment.
3. The operational surface for the flat shell hole must be pre-leveled to prevent any potential slippage or displacement during rock drilling. Achieving a stable and even surface is essential for precision and safety.
4. To uphold safety and efficiency, avoid dry drilling at all costs. Embrace the technique of wet rock drilling by initiating the water flow before activating the air. Conversely, cease air flow before turning off the water when concluding operations. Commence with a low-speed start and transition to full-speed drilling once an adequate depth is achieved.
5. Drill operators must adhere to safety protocols by refraining from wearing gloves during drilling operations. This precautionary measure is crucial for maintaining control and feedback during the process.
6. When utilizing the air leg for drilling, maintain proper posture and positioning. It is imperative not to exert pressure with your body or stand directly in front of the rock drill while it is in operation, as this could result in injury from a snapping brazing rod.
7. Should any unusual sounds or water discharge occur during rock drilling, immediately halt the machinery. Conduct a detailed inspection to diagnose and resolve any issues before resuming operations.
8. When retracting the rock drill or replacing the brazing rod, proceed with caution by operating the drill at a slow pace. Pay careful attention to the positioning of the rock drill braze to ensure a smooth and safe transition.
