vertical shaft

A vertical shaft is a tall, straight passage or opening that runs downward or upward through a structure, such as a building or mine. It is often used to move people, tools, or materials between different levels efficiently. In buildings, elevators are installed in vertical shafts to transport occupants. In mining, vertical shafts provide access to underground ore deposits. These shafts are designed with safety features and support systems to ensure stability and protection during operation. Overall, a vertical shaft serves as a core vertical route within a structure or site.
