    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.
