Preparations Before Using the Rock Drill:
1. Thoroughly inspect all components, including the rock drill, bracket, or rock drill cart, ensuring each part is intact and adequately lubricated. Confirm that the wind and water pathways allow for smooth operation, and check all connection joints to ensure they are securely fastened.
2. Carefully examine the roof of the working face for any live or loose rocks. Address and stabilize these conditions meticulously before commencing with the drilling operation.
3. Verify that the working surface is perfectly flat prior to drilling. This essential step prevents any potential slippage or displacement during the operation.
4. Maintain hydration of the drill at all times by using water. Initiate the drilling process with water flow, then introduce wind. Upon stopping, reverse the sequence: start with wind and end with water. Begin drilling at a low speed, transitioning to full speed only after achieving an appropriate depth in the material.
5. Operators should always refrain from wearing gloves while handling the drill to ensure maximum safety and control.
6. Maintain a mindful stance and positioning when employing the air leg. Avoid exerting pressure with your body weight and do not stand directly in front of the rock drill. This precaution is vital to prevent injuries from potential breakages of brazing rods.
7. If you detect any abnormal sounds or experience unexpected water discharge, pause the operation immediately. Conduct a thorough inspection and resolve any issues before resuming work.
8. Exercise caution when withdrawing the rock drill or changing the brazing rod. Operate the drill at a slow pace, being acutely aware of the brazing rod's position to ensure a safe exchange.
