YT27 Rock Drills: Essential Pre-Use GuidanceUnderstanding Pneumatic Rock Drills: What Are They?
2. Conduct a thorough examination of the roof near the work area. Ensure there are no live or loose rocks, particularly in the roof and second gang adjacent to the working face. Execute necessary stabilization procedures.
3. Prepare the flat shell hole's work surface meticulously by flattening it beforehand, ensuring stability for the rock drilling process. This prevents any slippage or displacement of the shell hole.
4. Dry drilling is strictly prohibited. Embrace wet rock drilling practices; initiate water flow before air and cease air before water when concluding operations. Begin with low-speed operations to establish the hole, then escalate to full speed once at a suitable depth.
5. Ensure drillers refrain from wearing gloves during the drilling process to maintain safety.
6. When utilizing the air leg for drilling, maintain a vigilant stance and position. Refrain from using your body for pressure and never stand in front of the rock drill beneath the working brazing rod to avoid injury from any brazing rod fractures.
7. Should you encounter any unusual noises or abnormalities in water discharge during rock drilling, halt operations immediately. Conduct a comprehensive inspection to determine and rectify the issue before resuming work.
8. During the withdrawal of the rock drill or when replacing the brazing rod, operate at a slow speed. Attentively monitor the position of the rock drill braze for safety.
