[0002] Coal seam: a layered solid combustible mineral formed by the transformation of plant remains through complex biochemical and geological processes. It is found in coal-bearing rock systems, between the top and bottom rocks. The number of layers, thickness, occurrence and burial depth of coal seams are restricted by paleo-tectonic, paleo-geographic and paleo-climatic conditions.

[0003] In application number: CN201920986240.1, a tunnel support device for inclined coal seams is disclosed. The sliding assembly can effectively support inclined coal seams at different angles. When the coal seams are inclined on both sides, the metal springs will slide left and right, and finally the arc-shaped top beam will be used for secondary support. The support assembly can increase the stability of the support frame during use, increase the support effect of the support frame, and prevent the first support tube and the second support tube from bending. At the same time, the support assembly is easy to fold and easy to carry. However, the above design still has shortcomings. The supporting force is limited. When supporting medium and thick coal seams, the supporting force is insufficient, which reduces its practicality.
