TECHNICAL FIELD

[0002] Coal resources are the lifeline of the development of basic industries, and ensuring the safety and stability of roadway surrounding rock is the prerequisite for efficient coal mining. With the gradual shift of mining to deep parts, the geological structure conditions and stress environment faced during roadway excavation are more complex, leading to severe deformation and damage of the surrounding rock of the excavated roadway, frequent maintenance, and significant increase in overall roadway support costs.

[0003] The surrounding rock of the roadway is commonly supported by anchor cables and steel belts, but for deep mine excavated roadways, the bending stiffness and support strength of the steel belts cannot meet the requirements of deep roadway support, and the steel belts are prone to bending deformation and tearing damage.

[0004] Some mines use U-shaped steel and anchor cable support to reinforce the surrounding rock of the roadway, but when the roadway faces complex geological conditions such as folds, faults, and large sections, the bending stiffness and support strength of traditional U-shaped steel are limited, and the surrounding rock still deforms during roadway excavation, not only causing the U-shaped steel structure to bend and deform, but also causing the anchor cables to shear and break when the U-shaped steel deforms.

[0005] A new V-shaped support beam assembly was disclosed in the CN216381442U Chinese utility model patent granted on April 26, 2022. The existing support beam has a small contact surface with the roof, which can easily cause the roof to be crushed and damaged, and the mechanical strength needs to be improved. Therefore, the new V-shaped support beam assembly includes a V-shaped support beam and N anchor rods or anchor cables. The V-shaped support beam includes a longitudinal ridge and two inclined side plates on both sides of the ridge. The longitudinal ridge of the V-shaped support beam has N through holes spaced apart. The anchor rods or anchor cables are correspondingly arranged in the through holes. N base plates are arranged inside the reinforced bottom edge at intervals. Each base plate is connected to the two sides of the reinforced bottom edge on both sides. Each base plate has a slot hole. The slot hole corresponds to the through hole and the anchor rod or anchor cable. After the anchor rod or anchor cable passes through the corresponding through hole and slot hole, it is inserted into the anchor hole of the mine roof. N is a positive integer, and N is greater than or equal to 2. The new V-shaped support beam assembly has a simple structure, a scientific design, a large stress area, and high mechanical strength, effectively improving the strength of the support beam.

[0006] The number and position of the base plates on the V-shaped supporting beam are fixed, and cannot be increased or decreased or moved, according to the utility model patent. SUMMARY
