YT27 Rock Drills: Pre-Operational ChecklistIntroduction to Pneumatic Rock Drills
2. Carefully inspect the roof near the working face by tapping it gently. This assessment is crucial to detect any loose or unstable rocks in the vicinity, allowing you to address potential hazards promptly and maintain a safe working environment.
3. Meticulously prepare the flat shell hole location on the working surface by pounding it flat in advance. This step is vital to prevent any slippage or displacement of the shell hole during the rock drilling process.
4. Adhere strictly to the practice of wet rock drilling. Avoid dry drilling at all costs. Begin by turning on the water before starting the wind; and remember to stop the wind before turning off the water upon completion. Initiate drilling at a low speed and accelerate to full speed once a certain depth is reached, ensuring precision and safety.
5. For safety reasons, drillers must refrain from wearing gloves during operation, ensuring maximum control and dexterity.
6. When employing the air leg for hole drilling, maintain an appropriate standing posture. Do not rely on your body for pressurizing, and never position yourself in front of the rock drill beneath the brazing rod to avoid injury from potential breakage.
7. Should you detect any abnormal sounds or irregular water discharge during rock drilling, halt operations immediately. Conduct a thorough inspection to identify and rectify the issue before resuming work, ensuring continuous productivity and safety.
8. When withdrawing the rock drill or exchanging the brazing rod, allow the rock drill to operate at a slow pace. Stay vigilant about the rock drill braze's position to ensure a smooth and safe transition.
