YT27 Rock Drills: Preparation and Use GuidelinesWhat is a Pneumatic Rock Drill?
2. Prior to drilling, conduct a thorough inspection of the roof near the working face. Ascertain that there are no live or loose rocks either above the roof or in the second gang adjacent to the working face. Undertake the necessary measures to secure the area.
3. Prepare the working surface meticulously. Ensure the flat shell hole location is levelled ahead of time to prevent any slippage or displacement during rock drilling.
4. Strictly adhere to wet rock drilling protocols. Always initiate with water flow before activating the wind, and cease wind before turning off the water upon completion. When commencing a drilling hole, start at a low speed, advancing to full speed only after reaching an adequate depth.
5. For safety, drillers must avoid wearing gloves during the drilling process to prevent accidents.
6. While utilizing the air leg to drill, maintain an appropriate stance and position. Refrain from using body weight for pressure, and never stand directly ahead of the rock drill under the work brazing rod to avert injury from potential broken brazing.
7. Should you encounter any unusual sounds or water discharge during rock drilling, promptly halt the operation for a thorough inspection. Identify and rectify the source of the issue before resuming the task.
8. When retracting the rock drill or changing the brazing rod, allow the rock drill to operate slowly and cautiously monitor the position of the rock drill braze to ensure safe handling.
