2. Conduct a safety inspection by tapping on the roof near the work area. Detect any live or loose rocks around the roof and second gang adjacent to your workspace and address them adequately to ensure safe operations.
3. Prepare the working surface meticulously by ensuring the flat shell hole location is perfectly leveled in advance. This precaution helps in preventing any potential slippage or displacement of the shell hole during the rock drilling process.
4. Uphold safety by forbidding dry-eye drilling. Embrace the practice of wet rock drilling by initiating water flow before air when operational, and halting air before water upon cessation. Begin with a low-speed approach when opening the hole, escalating to full-speed drilling as you reach a satisfactory depth.
5. For safety measures, drillers should refrain from wearing gloves during the drilling process.
6. When utilizing the air leg for hole drilling, maintain proper standing posture and positioning. Avoid applying body pressure or standing directly in front of the rock drill beneath the brazing rod while operational to prevent injuries from potential brazing fractures.
7. Should you encounter abnormal sounds or unusual water discharge during drilling, promptly halt the machine. Conduct a thorough inspection to identify and resolve the issue before resuming your drilling task.
8. During the withdrawal of the rock drill or while replacing the brazing rod, operate the rock drill at a slow pace and be vigilant of the positioning of the rock drill braze.
