Essential Preparations Before Employing the Rock Drill:
1. Carefully verify that all components, including the rock drill, its bracket, or the rock drill cart, are in impeccable condition and thoroughly lubricated. Ensure the pathways for wind and water are unobstructed, and all connection joints are firmly secure.
2. Conduct a meticulous inspection of the roof area close to the working face to detect and rectify any loose or potentially hazardous rocks before commencing any operation.
3. Prioritize establishing a flat and stable working surface before initiating drilling processes to prevent any risk of slippage or displacement.
4. Perform all drilling activities with water to mitigate the risks associated with dry drilling. Engage water flow first, followed by wind during operation, and reverse this sequence when halting. Start at a reduced speed, advancing to full speed once adequate depth is reached.
5. It is imperative for drill operators to refrain from wearing gloves during operations to ensure maximum safety.
6. Maintain correct standing posture and position while utilizing the air leg. Avoid applying pressure with your body and ensure you are not positioned directly in front of the rock drill to dodge potential injuries from fractured brazing rods.
7. Should there be any occurrence of unusual sounds or unexpected water discharge, it is crucial to immediately cease operations, conduct a thorough inspection, and address any issues before resuming activities.
8. During the process of withdrawing the rock drill or replacing a brazing rod, employ a slow and controlled speed, with careful attention to the positioning of the brazing rod to ensure smooth and safe operation.
