2. Conduct a thorough percussion on the roof proximate to the working face. This involves checking for any unstable or loose rocks on both the roof and second gang nearby, and taking the necessary remedial action to ensure safety.
3. Prepare the working surface for the flat shell hole by ensuring it is meticulously leveled in advance. This precaution prevents any slippage or unintended displacement of the shell hole during the drilling process.
4. Adherence to safe drilling practices is paramount. Avoid dry drilling by ensuring the use of wet rock drilling techniques. Start by turning on the water supply, followed by the wind. Conversely, when ceasing operations, turn off the wind first and then the water. Initiate the drilling at a slow speed, escalating to full speed only after achieving a substantial depth.
5. For optimal safety, it's crucial that drillers refrain from wearing gloves during the drilling operation.
6. When utilizing the air leg for hole drilling, maintain a mindful stance and position. Never rely on bodily force for pressure application, and avoid standing in front of the rock drill beneath the working brazing rod to preclude injury from potential breakage.
7. Should you encounter any unusual sounds or irregular water discharge during rock drilling, it is imperative to halt operations immediately. Conduct a thorough inspection to identify and resolve the issue before proceeding further.
8. During the withdrawal of the rock drill or replacement of the brazing rod, allow the drill to run at a reduced speed. Remain vigilant to the positioning of the rock drill braze for a secure and seamless transition.
