YT27 Rock Drills Before Use Guidelines:Understanding the Pneumatic Rock Drill: An In-Depth Look
2. Conduct a meticulous inspection of the working face by tapping the roof nearby. This involves checking for the presence of loose or potentially hazardous rocks at the roof and second gang close to the working zone. Address any identified risks with appropriate measures.
3. The designated shell hole location on the working surface must be leveled and prepared beforehand to facilitate rock drilling operations. This precautionary step is crucial to avert any slippage or displacement of the shell hole during the drilling process.
4. Upholding the standard of wet rock drilling is critical. Drilling dry eyes is strictly prohibited. Begin with the water supply, then initiate airflow during operation. Upon completion, cease airflow before shutting off the water. Start drilling at a reduced speed and transition to full speed only after achieving a certain depth.
5. For safety reasons, operators must refrain from wearing gloves while engaging in drilling activities.
6. When employing the air leg for drilling, maintain a proper standing posture and positioning. Avoid using body weight to apply pressure and never stand directly in front of the rock drill when the brazing rod is active to prevent injury from potential rod breakage.
7. Should any unusual noises or irregular water discharges occur during drilling, promptly halt operations to conduct a thorough inspection. Diagnose and resolve the issue before resuming any drilling activities.
8. During the withdrawal of the rock drill or when changing the brazing rod, it is advisable to operate the drill at a slow pace. Carefully monitor the positioning of the rock drill braze to ensure safety.
