Study Notes
Miner's Safety Regulations
- Miners' Self-Contained Self-Rescuers (SCSR) must be checked daily to ensure functionality.
- When transporting explosives, maintain a distance of 1/2 mile behind a mantrap for safety.
- Firefighting equipment should be positioned at least 25 feet from wooden doors where power lines are present.
Equipment and Speed Regulations
- If the roof height is 18 inches above a belt, the maximum allowable belt speed is 250 feet per minute (fpm).
- A roof height of 24 inches allows for a maximum belt speed of 300 fpm.
Escape Routes and Safety Protocols
- An escape line, also known as a lifeline, is critical in escape ways to follow during evacuation.
- A "fire boss" is the designated individual responsible for inspecting hazards before entry into the mine.
- Tags on Nip equipment must correspond to the equipment they power, ensuring accurate identification.
Escape Routes Maintenance
- Escape ways must be walked every 90 days to confirm safety.
- Each mining section should have at least two escape routes.
- One escape route must provide intake air to ensure safe breathing environment.
Equipment Interaction and Signaling
- When passing by running equipment, flag the operator with your cap light and wait for a response before proceeding.
- The "Red zone" refers to the area directly in front of moving equipment, highlighting a danger zone.
Communication Signals
- A circular motion of the cap light signifies "Come here."
- Up-and-down motion of the cap light signifies "Go or Yes."
- Back-and-forth motion of the cap light signifies "Stop or No."
Safety Measures for Hazards
- In case of roof slips, take immediate action to add additional support rather than ignoring the situation.
- A clay vein results from the formation of clay during the coal's creation process, requiring proper handling.
Tool Usage and Torque Specifications
- A torque wrench is essential for checking the correct torque on roof bolts to ensure secure installation.
- The roof control plan outlines specific torque requirements for bolts to maintain structural integrity.
Electrical Bonding
- A cross bond is utilized to connect copper wire between track rails, aiding in grounding.
- Rails must be properly bonded to enhance grounding rather than merely holding them in place or supplying power.
