Description

Technical Field

[0001] This utility model relates to the field of mining protection equipment, and in particular to a safety net for preventing falls during underground mining. Background Technology

[0002] In underground mining operations, suspended platform transportation is an important way to move personnel and equipment vertically. However, due to the characteristics of working at height, the risk of tools or materials falling is extremely high. Traditional fall prevention measures mostly rely on simple fences set up on the sides of the suspended platform for blocking.

[0003] However, although the simple fence can prevent some foreign objects from falling, when the speed of the basket transportation is unstable, some materials will fall from the basket due to inertia and swaying. The falling objects will affect the safety of the workers at the bottom of the mine.

[0004] Therefore, in order to reduce the impact of falling objects caused by unstable hoisting transport on workers, a safety net for preventing falls during underground mining is proposed. Utility Model Content
