[0002] Shaft construction technology plays a crucial role in modern engineering, especially in the fields of deep-earth resource extraction and underground space development. As an important passage for humans to enter deep underground space, the development technology of shafts is a key technological guarantee for deep-earth resource extraction and underground space development.

[0003] In shaft construction, emergency evacuation ladders (also known as safety ladders) play a crucial role, especially in emergencies such as fires, earthquakes, or other unforeseen events. Below are some key functions of emergency evacuation ladders in shaft construction: they provide fast and efficient evacuation routes, enabling construction workers to quickly leave the shaft in emergencies, reducing crowding and congestion, thereby improving evacuation efficiency.
