YT27 Rock Drills: Pre-Use GuidelinesUnderstanding Pneumatic Rock Drills
2. Prior to commencement, tap the roof around the working face. This vital step is to ascertain the presence of any loose or live rocks on the roof or the secondary gang near the working face. Address and rectify any potential hazards to fortify the safety of your operation.
3. The surface where the flat shell hole is to be drilled must be leveled meticulously in advance. This precautionary measure is pivotal in averting any slip or unwanted displacement of the shell hole during rock drilling.
4. Uphold the highest standards by prohibiting dry drilling. Embrace wet rock drilling by initiating water flow prior to air during operation. Conclude by reversing the sequence—air off, water off. Begin with a gentle, low-speed approach, advancing to full speed only upon achieving a certain depth in the hole.
5. For maximum safety, drillers must refrain from wearing gloves during the drilling process.
6. When utilizing the air leg for hole drilling, maintain a vigilant stance and optimal positioning. Never rely on your body for pressure. Avoid standing directly in front of the rock drill beneath the working brazing rod to mitigate the risk of injury from potential rod breakage.
7. Be alert to any unusual noises or unexpected water discharges during drilling. Should they occur, cease operations immediately to diagnose and rectify the issue before resuming your activities.
8. When retracting the rock drill or swapping the brazing rod, cautiously operate the drill at a slow pace. Keep a keen eye on the positioning of the rock drill braze to ensure a safe transition.
