YT27 Rock Drills – Essential Pre-Use GuidelinesUnderstanding Pneumatic Rock Drills: An Overview
2. Conduct a thorough inspection of the roof near the working face by tapping to detect any unstable or dislodged rocks. This includes evaluating the immediate second gang. Address any identified hazards promptly to ensure a safe working environment.
3. Prepare the working surface meticulously by ensuring that the flat shell hole location is pre-flattened. This proactive measure is crucial to prevent any potential slippage or unwanted displacement during rock drilling activities.
4. Adhere strictly to the prohibition of dry eye drilling. It is essential to maintain wet rock drilling practices by initiating water flow before air pressure when operating. Upon cessation, reverse this order by stopping the air before the water. Begin hole drilling at a cautious low speed, escalating to full speed only after achieving a suitable depth.
5. Drill operators must refrain from wearing gloves while engaged in drilling tasks to ensure maximum control and safety.
6. When employing an air leg for hole drilling, it is crucial to maintain a stable stance and proper positioning. Avoid pressurizing using body weight, and never position oneself in front of the rock drill or beneath the working brazing rod to avert potential injuries from brazing breakage.
7. Should any unusual sounds or irregular water discharge be detected during the drilling process, immediately halt operations. Conduct a thorough inspection to identify and rectify the issue before proceeding with drilling activities.
8. When withdrawing the rock drill or replacing the brazing rod, operate the rock drill at a reduced speed. Vigilantly monitor the position of the rock drill braze to ensure safe handling and operation.
