YT27 rock drills before use:What is a pneumatic rock drill?
2. Conduct a thorough examination of the working face's roof by knocking to detect any loose or live rocks. Address any instability on the roof and second gang near the working face with immediate and necessary treatment to ensure safety and smooth operations.
3. Prepare the work surface by pounding it flat at the flat shell hole location before drilling commences. This preemptive step is crucial to prevent slippage or displacement of the shell hole, ensuring precision and stability during the drilling process.
4. Embrace the practice of wet rock drilling, as dry drilling is strictly prohibited. Initiate the process by turning on the water first, followed by the wind. Upon stopping, reverse the order by turning off the wind before the water. Begin drilling at a low speed to establish a foothold, then accelerate to full speed once a certain depth is achieved for optimal performance.
5. Safety first: drillers should refrain from wearing gloves while operating the drill to prevent accidents and ensure dexterity and control over the equipment.
6. When utilizing the air leg for drilling, maintain a proper standing posture and position. Avoid applying pressure with your body or standing in front of the rock drill beneath the working brazing rod to prevent injuries from potential breakage.
7. Should you encounter any abnormal sounds or unexpected water discharge during rock drilling, halt operations immediately. Inspect the equipment thoroughly to identify and resolve the issue before proceeding, ensuring safety and effectiveness.
8. While withdrawing the rock drill or replacing the brazing rod, operate the rock drill at a slow pace. Pay close attention to the positioning of the rock drill braze to execute these tasks smoothly and safely.
