Description

Technical Field

[0001] This utility model relates to the field of coal mine road slab technology, and in particular to a coal mine road slab made of polyethylene material. Background Technology

[0002] Polyethylene (PE) road slabs for coal mines were developed to address the shortcomings of traditional coal mine road surface materials and the specific needs of the underground coal mine environment. Traditional cement pavements are prone to damage and water accumulation during transportation in coal mine tunnels and are not recyclable; metal materials, on the other hand, have poor wear resistance and impact resistance, are easily corroded, and are heavy. The harsh underground coal mine environment presents challenges such as roof pressure, floor heave, surrounding rock deformation, and groundwater seepage, while also demanding high standards for the flame retardancy, load-bearing capacity, and anti-slip properties of road surface materials. Polyethylene possesses excellent properties such as compressive strength, impact resistance, chemical corrosion resistance, anti-slip properties, and flame retardancy. Furthermore, it is easy to install and recyclable, perfectly meeting the needs of underground coal mine road surface materials. Therefore, it was developed for the production of coal mine road slabs.

[0003] Existing polyethylene panels are mostly installed by placing them directly on the ground or by connecting them with bolts. This connection and installation process is time-consuming, and replacing some polyethylene panels is troublesome when using bolts. Therefore, a coal mine road panel made of polyethylene material is proposed. Summary of the Invention

[0014] (III) Beneficial Effects

[0015] This utility model provides a coal mine road panel made of polyethylene material, which has the following beneficial effects:

[0016] 1. The coal mine road panel made of this polyethylene material, through the setting of the snap-fit ​​assembly, allows for the sliding of a movable plate during use. The movable plate moves, causing a movable rod to move inside the fixed sleeve rod. The return spring is in a compressed state, connecting multiple sets of polyethylene plates together. When the movable plate is released, the return spring causes the movable plate and movable rod to be limited. The plug rod is inserted into the limiting hole, allowing the polyethylene plates to be partially replaced or adjusted according to actual needs, improving the system's flexibility and adaptability. At the same time, it also allows for the rapid installation and disassembly of multiple sets of polyethylene plates, reducing the time construction personnel spend underground and lowering construction risks.

[0017] 2. The coal mine road panel made of this polyethylene material, through the setting of the reinforcing components, can effectively distribute pressure and reduce deformation and damage caused by excessive local stress during use. It can significantly improve the compressive strength of the polyethylene board. At the same time, the reinforcing rods can effectively prevent the polyethylene board from sinking or deforming locally due to uneven stress, maintain the flatness and stability of the road surface, and thus extend the service life of the device.
