Description

Large-section open-cut self-adaptive supporting device based on composite material anchor rod Technical Field The utility model relates to the technical field of coal mine open-cut eye support, in particular to a large-section open-cut eye self-adaptive support device based on a composite material anchor rod. Background In the coal mining process, "open-cut" is a term of art that refers to the creation of an initial path in a coal seam for subsequent coal mining operations, which is one of the important steps in the preparation phase of coal mining. The main purpose of the open cut is to create a working face for installing coal mining equipment and performing subsequent coal mining operations. In the process of opening and cutting eyes, a series of supporting operations are carried out simultaneously so as to ensure the stability and the safety of the roadway. These support measures are critical to the safety of personnel and equipment. In particular, the support operation generally includes the use of support devices such as bolts, brackets, and the like to prevent the roadway from collapsing. Some existing fixed height support devices often perform poorly when used due to their design limitations. For example, if the supporting device cannot be adjusted according to the actual situation, instability of the top of the roadway may be caused, and the risk of roof collapse is increased, so that life safety of miners is seriously threatened.
