YT27 Rock Drills Preparation: Essential Pre-Use StepsUnderstanding the Pneumatic Rock Drill: A Comprehensive Overview
2. Conduct a careful assessment of the roof near the working face. This involves checking for any live or loose rocks both on the roof and the second gang close to the working face. Implement necessary treatments to mitigate any detected risks.
3. Prior to rock drilling, ensure that the working surface around the flat shell hole location is adequately pounded flat. This precautionary measure is essential to prevent any slippage or unwanted displacement of the shell hole during operations.
4. Under no circumstances is dry eye drilling permitted. It is imperative to adhere to wet rock drilling methods. Initiate your operation by turning on the water first, followed by the wind. Conversely, when stopping, turn off the wind before the water. Begin the hole opening at a low speed, transitioning to full speed only after achieving a necessary depth.
5. For safety reasons, drillers must not wear gloves while performing drilling tasks.
6. When employing the air leg for hole drilling, maintain a mindful awareness of your standing posture and positioning. Avoid applying body pressure and never stand directly in front of the rock drill while operating under the work brazing rod. This safety precaution is vital for preventing potential injuries from broken brazing.
7. Be vigilant for any abnormal sounds or irregular water discharge during rock drilling. Should these occur, promptly halt the machine for a thorough inspection. Identify and address the issue before resuming drilling activities.
8. During the withdrawal of the rock drill or while replacing the brazing rod, operate the rock drill at a slow pace. Carefully monitor the position of the rock drill braze to ensure safe handling and operation.
