YT27 Rock Drills Before Use: A Comprehensive GuideUnderstanding the Pneumatic Rock Drill: What Is It?
2. Conduct a safety check by tapping on the roof near the working face. This helps identify any loose or unstable rocks that might pose a danger. Address any live or precarious rocks on the roof or second gang near the work area to ensure a safe working environment.
3. The flat shell hole's location on the working surface must be stabilized in advance. This preemptive flattening ensures safety and prevents any unintended slippage or displacement during rock drilling operations.
4. Adhere strictly to proper wet drilling practices—avoid dry drilling at all costs. Initiate the operation with water and then start the airflow. Upon completion, reverse the order by switching off the airflow first. Begin drilling at a low speed, gradually ramping up to full speed once a certain depth is reached to ensure precision and safety.
5. To ensure maximum safety, drillers must refrain from wearing gloves during the operation, as this could compromise their handling and control of the equipment.
6. When employing the air leg for drilling, maintain an appropriate and safe posture. Avoid using your body to exert additional pressure and never position yourself in front of the rock drill beneath the working brazing rod, as this can pose a serious injury risk in case of equipment failure.
7. Should you encounter any unusual sounds or irregular water discharges during drilling, cease operations immediately. Investigate and resolve the issue before resuming to ensure efficient and safe drilling.
8. While retracting the rock drill or replacing the brazing rod, operate at a reduced speed. Be vigilant about the position of the rock drill braze to avoid misalignment or accidents.
