YT27 Rock Drills: Pre-Operational Check and Preparation GuidelinesUnderstanding the Power of Pneumatic Rock Drills
2. Conduct a preliminary safety check by tapping the roof near the working face. This ensures detection and management of live or loose rocks on the roof and the adjacent gang, facilitating a safer drilling environment.
3. Prepare the working surface meticulously by flattening the shell hole location in advance. This precaution is vital to prevent slippage or displacement during the rock drilling process.
4. Adhere strictly to wet rock drilling protocols: initiate water flow before air, and shut off air before water upon completion. Start drilling at low speed, gradually accelerating to full speed after achieving adequate depth to ensure operational precision and safety.
5. Safety first: Drillers must refrain from wearing gloves during drilling operations to maintain optimal control and prevent accidents.
6. Exercise caution with air leg usage. Maintain a stable standing position, avoiding body pressure application or standing directly in front of the rock drill when using the work brazing rod, to minimize injury risk.
7. Halt operations immediately if abnormal noises or water discharge occur during drilling. Conduct a thorough inspection to diagnose and resolve the issue before resuming.
8. During rock drill withdrawal or brazing rod replacement, operate the rock drill at a reduced speed. Pay close attention to the positioning of the rock drill braze to ensure a smooth and safe transition.
