YT27 Rock Drills: Pre-Operational ChecklistWhat is a Pneumatic Rock Drill?
2. Conduct a sound integrity assessment of the roof near the working face. This involves detecting any unstable rocks or loose areas on the roof and second gang near the working face, followed by essential corrective measures.
3. Prioritize preparing the working surface by smoothing the flat shell hole location meticulously. This proactive approach prevents any slippage or displacement during the rock drilling process.
4. Adhere to strict safety protocols by forbidding dry drilling. Commit to wet rock drilling methods by initiating water flow prior to air when drilling and reversing this sequence when stopping. Begin drilling at a reduced speed to gain depth, then transition to full speed.
5. In the name of safety, all drill operators must refrain from wearing gloves during drilling operations.
6. When employing an air leg for drilling, maintain vigilant awareness of your stance and positioning. Avoid applying body pressure and never position yourself in front of the rock drill or beneath the work brazing rod to mitigate injury risks.
7. If unusual sounds or abnormal water discharge is observed during drilling, promptly halt operations. Conduct a detailed inspection to diagnose and resolve the issue before resuming.
8. During the withdrawal of the rock drill or while replacing the brazing rod, operate at a slow pace. Maintain heightened awareness of the brazing rod's position throughout the process.
