Mining shed steel support
29U steel support is primarily utilized for mine tunnels, secondary support in mine tunnels, and support in mountain tunnels. It is also employed in lifting straight wall semi-arched sheds in Ready Roadway Intersections, yielding significant outcomes. Optional retractable U-shaped steel support addresses tunneling support challenges.
