2. Diligently inspect the roof near the work area to identify any loose or unstable rocks. Conduct a thorough assessment and perform any required stabilization measures for safety.
3. The working surface for flat shell hole placement must be pre-flattened adequately to avert slippage or displacement during rock drilling operations.
4. Avoid dry drilling at all costs. Commit to wet rock drilling by initiating water flow prior to wind commencement. Upon completion, cease wind operations before halting water flow. Begin drilling at a low speed, escalating to full speed upon reaching a significant depth to ensure precision.
5. For safety, drillers must abstain from wearing gloves during drilling.
6. When utilizing an air leg for drilling, maintain an optimal standing posture. Refrain from applying pressure with the body and never position yourself in front of the rock drill with the brazing rod, mitigating risk of injury from potential breakage.
7. Should abnormal sounds or irregular water discharge occur during rock drilling, immediately pause operations for inspection. Diagnose and resolve the issue prior to resuming drilling to maintain safety and efficiency.
8. When retracting the rock drill or changing the brazing rod, allow the rock drill to operate slowly. Remain cognizant of the rock drill braze's position to ensure a safe and controlled transition.
