What defines a "working place" in the context of a coal mine?

A "working place" in a coal mine is specifically defined as the area inby the last open crosscut. This definition is crucial because it represents the part of the mine where active mining operations are taking place. This area is where miners extract coal and where various tasks relating to the extraction process occur.

In the context of mine operations, identifying the working place is vital for ensuring safety protocols are followed and that appropriate ventilation, lighting, and equipment are adequately maintained. It is also an area under constant observation for hazards, ensuring a safe working environment for all personnel.

The other options do not accurately capture the definition of a working place. The area beyond the open pit typically refers to surface mining operations rather than underground working places. The entry point for coal transportation, though important for logistics, does not define where mining activity occurs. Similarly, the section that stores extracted coal does not align with the operational focus of a working place, as storage areas are separate from active mining zones.
