Preparing the YT27 Rock Drill for Optimal Performance:Understanding the Pneumatic Rock Drill: What It Is and How It Works
2. Conduct a thorough inspection by tapping the roof adjacent to the work area. This is to check for any unstable or loose rocks around the roof and the secondary gang, and address any issues found immediately.
3. Prepare the shell hole site on the work surface by pre-flattening it, ensuring a stable base for drilling. This precaution helps prevent any slippage or displacement of the shell hole.
4. Strictly avoid dry drilling; always choose wet rock drilling. Initiate the water flow before starting the air supply and reverse the process when stopping. At the start of drilling, operate at a low speed, then increase to full speed once a certain depth is reached.
5. Safety first: Drillers must refrain from wearing gloves during operations to maintain dexterity and avoid accidents.
6. When using the air leg for drilling, maintain a correct standing posture without using body weight for pressure. Never stand in front of the drill or under the working brazing rod to prevent injury from potential breakages.
7. If you detect any unusual sounds or irregular water discharge during drilling, immediately halt operations to inspect and resolve the issue before safely resuming work.
8. When withdrawing the rock drill or changing the brazing rod, allow the drill to operate slowly. Pay careful attention to the position of the brazing rod to ensure safety and precision.
