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.
