DETAILED DESCRIPTION
[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments: See also Figures 1 to 6 An elastic magnetic rope mine slope protection device includes a hollow magnetic anchor rod 1, a cable 2, a steel truss 3, an electromagnetic lock 4, a first elastic magnetic rope 5 and a second elastic magnetic rope 6. The hollow magnetic anchor rod 1 is arranged at the four corners of the steel truss 3 through the cable 2, and an electromagnetic lock busbar 41 is installed at equal distances at the center of the inner wall of the steel truss 3. The first elastic magnetic rope 5 and the second elastic magnetic rope 6 are criss-crossed and connected and arranged on the inner wall of the steel truss 3.
[0013] Preferably, a drill bit 13 is provided at the front end of the hollow magnetic anchor rod 1, and a magnetic ring 12 is sleeved around the hollow magnetic anchor rod 1, and grouting holes 11 are opened between adjacent magnetic rings 12. The drill bit 13 is used to discard the rock formation; the hollow magnetic anchor rod 1 is equipped with magnetic rings 12 and grouting holes 11; the injectable magnetic slurry is injected from the grouting hole 11, and the magnetic ring 12 magnetically absorbs the magnetic slurry, so that the magnetic slurry can be distributed around the hollow magnetic anchor rod 1. The injected magnetic slurry can have a bonding strength with the rock formation of ≥3MPa. After four hollow magnetic anchor rods 1 are drilled into the rock formation and the magnetic slurry is injected, the bonding strength between the slurry and the rock formation is high enough to fix the upper and lower ends of the steel truss 3.
[0014] Preferably, the steel truss 3 can be fixed to the mine slope at four points around it by the hollow magnetic anchor rod 1. The fixing of the hollow magnetic anchor rod 1 carrying the steel truss 3 can reinforce the mine slope and improve the structural utilization rate.
[0015] Preferably, an electromagnetic lock busbar 41 is evenly arranged in the middle of the inner wall of the steel truss 3. The electromagnetic lock busbar 41 can lock the magnetic buckle end 42 by controlling the electromagnetic force, thereby fixing the first elastic magnetic rope 5 and the second elastic magnetic rope 6. After the first elastic magnetic rope 5 and the second elastic magnetic rope 6 are installed, they can be tested during subsequent use. If one of them does not meet the safety requirements, the electromagnetic buckle can be unfastened and replaced. Compared with the traditional replacement of the protective net, the device can replace one separately, which improves the economic and safety benefits.
[0016] Preferably, the first elastic magnetic rope 5 and the second elastic magnetic rope 6 are alternately arranged up and down and left and right inside the steel truss 3. Falling rocks can be blocked, reducing the safety hazards of pedestrians and mining workers passing by the mine slope.
[0017] Preferably, the first elastic magnetic rope 5 and the second elastic magnetic rope 6 are arranged in a staggered manner to form a mesh structure, and tire rubber 61 is arranged on the upper surface. The middle lines of the tire rubber 61 can be paved with gravel, rock and soil, etc., which are suitable for vegetation growth. The tire rubber can use waste tires, and the tire rubber can reduce the impact of falling rocks to protect the magnetic rope; the middle lines of the tire rubber can be paved with soil materials suitable for vegetation growth, such as gravel, clay, etc.; it can not only achieve the recycling of waste tire rubber resources, but also green the slopes, beautify the slopes and improve the ecology.
[0018] Preferably, the first elastic magnetic rope 5 and the second elastic magnetic rope 6 have a magnetic chain 52 inside, electromagnetic magnetic buckle ends 42 at both ends, and are wrapped with a rubber elastic rope 51 outside. The external rubber elastic rope 51 wraps the electromagnetic lock buckle 4 and the magnetic chain 52, which can dissipate the gravity of falling rocks, resist some rainwater and air chemical corrosion, and protect the internal important structures.
[0019] In addition, the present invention also discloses a method for using an elastic magnetic cable mine slope protection device, comprising the following steps: Step 1: On-site investigation and design: First, conduct a detailed investigation of the mine slope, evaluate the slope stability, and design a suitable layout of protective devices based on the characteristics of the surrounding environment; Step 2: Install the steel truss 3, determine the fixing point, fix it to the end of the mine slope that needs to be protected through the hollow magnetic anchor rod 1, drill into the hollow magnetic anchor rod 1, inject magnetic slurry, and test the bonding strength; Step 3: Install the elastic magnetic cable system: fix the electromagnetic lock end 4 of the magnetic spring lock at the top and bottom respectively, straighten the magnetic chain 52 and the rubber elastic rope 51 wrapped outside; Step 4: Use an inclinometer to detect whether the first elastic magnetic rope 5 and the second elastic magnetic rope 6 are straightened. At the same time, a sound detection system is established in the later stage to replace the damaged first elastic magnetic rope 5 and the second elastic magnetic rope 6 in time; Step 5: Lay the tire rubber 61 on the mesh surface formed by the first elastic magnetic rope 5 and the second elastic magnetic rope 6, and lay soil materials suitable for vegetation growth such as gravel and clay in the texture of the tire rubber 61.
