Preparation Steps for Using the YT27 Rock DrillUnderstanding the Pneumatic Rock Drill: An Essential Tool for Modern Mining
2. Perform a thorough assessment of the roof near the operational face. Check diligently for any loose or precarious rocks, ensuring the safety and stability of your working environment through necessary preventive measures.
3. Preparation of the working surface is paramount. Level the shell hole location meticulously in advance to thwart any potential slippage or displacement during the rock drilling process.
4. Adherence to wet drilling practices is critical. Refrain from dry drilling, rather engage in wet rock drilling by initially activating the water flow followed by the air. When halting operations, cease the air before the water. At the onset, initiate hole opening at a slow pace, progressing to full-speed drilling upon reaching sufficient depth.
5. Drill operators must refrain from wearing gloves during the drilling process to maintain optimal safety and control.
6. When employing the air leg for drilling, maintain a proper stance and positioning. Avoid using bodily pressure and never stand directly in front of the rock drill or underneath the working brazing rod, thereby preventing injury from potential brazing breakage.
7. Should you encounter unusual sounds or irregular water discharge during drilling, halt the operation immediately. Perform a comprehensive inspection to diagnose and resolve the issue before resuming operations.
8. Exercise caution when retracting the rock drill or replacing the brazing rod. Operate the rock drill at a slow speed and be vigilant about the brazing rod's position to ensure operational safety.
