YT27 Rock Drills: Essential Preparations Before UseWhat Is a Pneumatic Rock Drill?
2. Conduct a thorough assessment of the roof in proximity to the working face. This includes diligently checking for any live or loose rocks on the roof and the secondary gang near the working face. Implement necessary safety measures to mitigate potential risks.
3. The designated area for the flat shell hole must be pre-flattened meticulously before commencing rock drilling operations. This preemptive measure averts slippage or displacement of the shell hole, ensuring a stable and secure drilling environment.
4. Adherence to wet rock drilling is paramount; dry drilling is strictly prohibited. Initiate the water flow prior to activating the wind when operating, and cease the wind flow before shutting off the water upon conclusion of drilling. Commence drilling at low speed to establish the hole, then proceed to full speed upon reaching a sufficient depth.
5. Drill operators must refrain from wearing gloves during the drilling process to avoid potential hazards.
6. When employing the air leg for drilling, maintain correct standing posture and position. Avoid using body weight for pressurization and never position oneself in front of a working brazing rod to prevent injuries from broken brazing.
7. Should any abnormal sounds or irregular water discharge occur during rock drilling, halt operations immediately for thorough inspection. Identify and rectify the cause before resuming drilling activities to ensure safety and efficiency.
8. During the withdrawal of the rock drill or when replacing the brazing rod, allow the rock drill to operate at a slow pace while vigilantly monitoring the position of the rock drill braze to ensure precision and safety.
