YT27 rock drills before use:What is a pneumatic rock drill?
2. Perform a safety precaution by tapping on the roof near the operational working face. Detect any presence of live or loose rocks within the roof and in the second gang area near the working face. Take the necessary actions to treat and secure them effectively.
3. For a stable drilling operation, ensure the working surface at the flat shell hole location is prepared by pounding it flat before commencing rock drilling. This precaution helps in preventing any slippage or displacement of the shell hole.
4. Adhere strictly to wet rock drilling techniques by initiating the water supply before engaging the wind. When halting, cease the wind supply prior to stopping the water. At the outset of hole opening, begin with low speed to achieve precision, then proceed to full speed once a certain depth is reached. Dry eye drilling is strictly prohibited.
5. For safety, drillers must refrain from wearing gloves while engaged in the drilling process.
6. During hole drilling with the air leg, maintain a vigilant posture and position. Avoid applying pressure using your body and never stand in front of the rock drill when the work brazing rod is engaged, to prevent injury from any unexpected brazing rod breakage.
7. If an unusual sound or abnormal water discharge is observed during rock drilling, immediately cease operations. Conduct a thorough inspection to identify and resolve the issue before resuming the drilling process.
8. When retracting the rock drill or replacing the brazing rod, operate the rock drill at a slow pace. Remain cautious and attentive to the position of the rock drill braze throughout these procedures.
