Description

Technical Field

[0001] The present invention belongs to the technical field of anchor cable cutting protection, and particularly relates to a mine-used anchor cable cutting device and a construction method thereof. Background Technique

[0002] The anchor cable support is an active support structure, which can significantly improve the stability of surrounding rocks and become the main support form for mine roadways. At present, the anchor cable support is widely used in major mines at home and abroad, and good results have been achieved. The anchor cable support enhances the bearing capacity of the surrounding rocks and controls the deformation of the surrounding rocks of the roadway. However, it also causes the roof of the roadway and the nearby goaf to be not easily caved after the mining is completed, and the goaf cannot be filled in time to support the overlying strata. In addition, the sudden caving of a large area of hanging roof causes a large area of abutment pressure, which is easy to cause equipment damage and casualties. Therefore, it is crucial to release the acting force of the roof anchor cable in the roadway behind the working face in time after the mining is completed.

[0003] For example, a hydraulic shear for cutting anchor cables disclosed in a patent publication number CN217192872U includes a hydraulic box with a hydraulic station installed inside, a first hydraulic cylinder vertically installed on the top of the hydraulic box, and a shearing mechanism installed at the output end of the top of the first hydraulic cylinder. The shearing mechanism includes a Y-shaped fixed seat fixed to the output end of the first hydraulic cylinder. Two blades that can slide along the length direction of the fixed seat are staggered inside the fixed seat. The two blades are driven by second hydraulic cylinders on both sides of the fixed seat. Cutting edges arranged along the width direction are formed on the opposite sides of the two blades. The first hydraulic cylinder and the second hydraulic cylinder are both connected to the hydraulic station through oil pipes. By pushing the shearing mechanism vertically by the first hydraulic cylinder, anchor cables of different heights can be sheared. After using the second hydraulic cylinder to push the two blades to move towards each other, high-strength anchor cables can be quickly sheared at one time.

[0004] A large area of the hard roof above the goaf is suspended without corresponding caving, resulting in a gradually increasing suspended area of the roof above the goaf behind the working face. A large amount of elastic energy accumulates in the roof, which is prone to cause the sudden caving of a large area of hanging roof, resulting in a large area of abutment pressure, and is easy to cause equipment damage and casualties. Therefore, it is necessary to cut the anchor cable from the anchoring end to make it lose the suspension effect and realize the natural caving of the hanging roof. Moreover, during the cutting process of the anchor cable, a supporting force needs to be applied to the roadway roof to avoid the collapse of the roadway roof during the cutting process of the anchor cable. Therefore, it is necessary to invent a device that can quickly and accurately remove the roof anchor cable in the roadway so that the roof can cave in time. Summary of the Invention
