YT27 Rock Drills Before Use: Guidelines and PreparationsUnderstanding the Pneumatic Rock Drill: Your Essential Mining Companion
2. Safety first! Gently tap the roof near the working face to assess if any live or loose rocks may pose a hazard in the roof or second gang adjacent to the working face, and carry out any necessary precautionary measures.
3. For a flawless drilling experience, ensure that the working surface of the flat shell hole is pounded flat in advance to prevent any slippage or misalignment during the operation.
4. Adhere to safety by strictly avoiding dry drilling. Prioritize wet rock drilling; initiate with water first, followed by wind when working, and reverse the order when halting the drill. Begin at a gentle low speed when starting a hole, and progress to full speed only after reaching a satisfactory depth.
5. Safety protocol dictates that no gloves should be worn by operators while drilling to maintain dexterity and control.
6. When employing the air leg for drilling, mind your posture and position attentively. Do not rely on body weight for pressure, and avoid standing in the trajectory of the rock drill or beneath the work brazing rod to prevent potential injury from any broken brazing.
7. In the event of abnormal sounds or unexpected water discharge during drilling, promptly halt operations to inspect and identify the issue. Address the root cause before resuming the procedure.
8. Exercise caution when withdrawing a rock drill or swapping the brazing rod. Operate the rock drill at a reduced speed and keep vigilant about the positioning of the rock drill braze.
