YT27 Rock Drills: Pre-Operational Excellence GuideUnderstanding the Pneumatic Rock Drill: A Brief Overview
2. Hazards Elimination: Proactively examine the roof near the active work face by knocking – this crucial step identifies precarious live and loose rocks. Address any detected hazards with precision to maintain a safe working environment.
3. Stability First: For precision in rock drilling, prepare the shell hole location by thoroughly leveling it in advance. This pre-drilling action prevents any undesirable slippages or displacements, ensuring the accuracy and safety of your operation.
4. Commitment to Wet Drilling: Say no to dry drilling! Always engage in wet rock drilling by initiating water flow before activating the wind. Reverse the sequence for shutdowns: wind off first, then water. Begin with a gentle low-speed to establish a depth before ramping up to full-speed drilling for optimal performance.
5. Safety Attire Alert: Drill operators must refrain from wearing gloves during operations to maintain dexterity and safety.
6. Posture and Safety: When drilling with an air leg, maintain optimal posture and positioning. Avoid using your body weight to pressurize, and never stand in front of the rock drill's working brazing rod to prevent injury from any unexpected breaks.
7. Operational Vigilance: Should you detect any abnormal sounds or irregular water discharge while drilling, immediately halt operations. Investigate thoroughly to identify and rectify the cause before resuming to ensure continued safety and efficacy.
8. Precision in Withdrawal: Exercise caution when retracting the rock drill or changing the brazing rod. Allow the rock drill to run slowly and keep an attentive eye on the brazing position to maintain control and safety.
