Guidelines for the YT27 Rock Drill Preparation:Understanding Pneumatic Rock Drills: An Introduction
2. Conduct a careful examination of the roofing close to the work face. Tap lightly to discern any loose or live rocks on the roof and the second gang near the work face, implementing necessary safety measures as needed.
3. Prepare the shell hole location diligently on the work surface. It must be flattened meticulously in advance to ensure stability and prevent any unwanted slippage or displacement during rock drilling.
4. Uphold the standard of wet drilling consistently; dry drilling is strictly prohibited. Start the process by turning on the water before the wind and reverse the procedure when stopping. When initiating drilling, commence at a low speed and escalate to full speed only after reaching a substantial depth.
5. Safety first — drillers must refrain from wearing gloves during operation to maintain optimal control and safety.
6. When employing the air leg for drilling, maintain an appropriate standing posture and position. Avoid using body weight for pressurization, and never position yourself in front of the rock drill beneath the work brazing rod to avoid injury from potential breakage.
7. Should you detect any irregular sounds or abnormal water discharge while drilling, halt the operation immediately. Conduct a thorough inspection to identify and rectify the underlying cause before proceeding.
8. While retracting the rock drill or swapping the brazing rod, operate the drill at a slow pace. Remain vigilant about the position of the brazing rod to ensure smooth and safe transitions.
