What must be provided at coal mining sections producing over 300 tons of coal per shift?

In coal mining operations, safety protocols are critical, especially in sections producing substantial amounts of coal, such as over 300 tons per shift. The requirement of providing two portable fire extinguishers and 240 pounds of rock dust is based on enhancing fire safety measures and controlling the potential for coal dust explosions.

Portable fire extinguishers are crucial for immediate response to any fire incidents that may arise during mining operations, particularly in environments where flammable materials are present. Providing two extinguishers ensures that there is adequate coverage and availability in different parts of the section, allowing for effective firefighting measures to be deployed quickly.

Rock dust plays a significant role in minimizing the risk of explosions caused by coal dust. By requiring 240 pounds of rock dust, this standard helps to ensure that there is enough material to suppress any ignitable dust that may accumulate. The application of rock dust creates a non-combustible layer that can help prevent or mitigate the consequences of an explosion.

This combination of fire extinguishers and rock dust aligns with regulations designed to protect miners and maintain a safer working environment. It reflects a comprehensive approach to hazard management in coal mining operations, crucial for minimizing risks associated with fire and explosions.
