A mine shaft is a vertical or near-vertical tunnel that provides access to underground mineral resources. It typically consists of a hoisting system that transports miners, equipment, and extracted materials between the surface and various levels of the mine. The shaft is supported by structures to ensure stability and safety, while ventilation systems are installed to supply fresh air and remove harmful gases. Overall, the mine shaft is essential for efficient resource extraction and worker safety in underground mining operations.
