Technical Field

[0001] The utility model relates to the technical field of support frames, in particular to a support frame which is easy to assemble quickly. Background Art

[0002] Underground mining refers to a mining method in coal mining that is opposite to open-pit mining. Compared with open-pit mining, underground mining technology is much more difficult, but since most coal mines are buried underground, underground mining must be adopted. Underground mining is the most important method. When conducting underground mining operations, corresponding support frames need to be installed in the mine tunnel. The support frames provide certain support to the mine tunnel to ensure the safety of construction operations.
