2. Conduct a thorough inspection by tapping the roof near any working face. This crucial step involves checking for any loose or potentially dangerous live rocks on the roof and immediate working area. Address any issues promptly to maintain safety.
3. Ensure the working surface of the flat shell hole location is well-prepared by pounding it flat in advance. This preparation is essential to avert slippage or displacement of the shell hole during rock drilling operations.
4. Uphold strict safety by prohibiting dry drilling. Always engage in wet rock drilling by turning on the water supply first, followed by the wind. When ceasing operations, turn off the wind prior to the water. During the initial drilling phase, operate at low speed, transitioning to full speed only after achieving adequate hole depth.
5. For safety, drillers must refrain from wearing gloves during the drilling process.
6. When employing the air leg for drilling, maintain a cautious posture and position. Avoid using body weight for pressure and never stand directly in front of the rock drill beneath the working brazing rod to prevent injury from potential breakages.
7. Stay alert to any unusual sounds or irregular water discharge during drilling. Should such anomalies occur, halt operations immediately for inspection. Identify and rectify the cause before resuming the drilling process.
8. When retracting the rock drill or changing the brazing rod, ensure the rock drill operates at a slow pace. Pay careful attention to the position of the rock drill braze, ensuring it is accurately aligned.
