2. Roof Check: Take a moment to knock on the roof near the working face, assessing for live or loose rocks in the vicinity. Address any identified risks with appropriate treatment to ensure a secure working environment.
3. Prepare the Surface: The working surface must be meticulously prepared by leveling the flat shell hole location in advance. This vital step prevents any risk of slippage or displacement during rock drilling operations.
4. Wet Drilling Protocol: Adhere to wet rock drilling practices by turning on the water first, then the wind. Conclude the process by turning off the wind before the water. Begin with a low-speed start when opening the hole, transitioning to full speed only after reaching a certain depth.
5. Safety Gear Advisory: Drillers are advised against wearing gloves during operations to maintain optimal control and safety.
6. Proper Stance: When utilizing the air leg for drilling, maintain a safe standing posture and avoid using body pressure. Never position yourself in front of the rock drill or beneath the working brazing rod to prevent injury from potential brazing breakage.
7. Anomalies Alert: Should you encounter any abnormal sounds or water discharge during drilling, halt the operation immediately. Conduct a thorough inspection to identify and resolve the issue before resuming work.
8. Withdrawal Precautions: When retracting the rock drill or switching the brazing rod, allow the rock drill to run slowly. Maintain awareness of the rock drill braze's position throughout the process to ensure safe handling.
