Description

Technical Field

[0001] This utility model provides a slope stabilization mechanism for open-pit coal mining areas, belonging to the field of slope protection technology. Background Technology

[0002] The mining process in open-pit coal mines typically involves first excavating a clearing before expanding operations. Due to the low slope stability of open-pit coal mines and their susceptibility to geological conditions, landslides are prone to occur, sometimes even endangering the lives of workers. To prevent landslides, protective netting is usually used to cover the slopes.

[0003] The existing structure, which uses active protective netting to cover the slopes of open-pit coal mines and reinforced with anchor bolts driven into the rock and soil, can basically meet normal usage needs. However, it still has certain drawbacks: relying solely on the protective netting for blocking, in severe rainy weather, rainwater can directly wash over a large area of ​​the open-pit coal mine slope, easily knocking down many small, unstable pieces of coal from the surface. In severe windy weather, the individual anchor bolts can only hold down the protective netting at a specific point, allowing localized areas to be blown away by the wind, significantly affecting the stability of the open-pit coal mine slope. Therefore, the protective effect needs improvement. Based on this, this utility model provides a slope stabilization mechanism for open-pit coal mine mining areas. Utility Model Content

[0004] The technical problem solved by this utility model is that rainwater can directly wash over a large area of ​​the slope, easily causing a large number of small, unstable coal slabs on the surface of the slope to roll off. Individual anchor bolts can only hold down the protective netting at a certain point, causing the protective netting to be blown up by strong winds in some areas, which greatly affects the stability of the open-pit coal mine slope and the protective effect needs to be improved.

[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: a slope stabilization mechanism for open-pit coal mining areas, including a protective net, and several stabilizing components arrayed on the protective net. The stabilizing components include a central block, hollow plates arranged in a cross pattern on the four side walls of the central block, an adjusting plate slidably inserted at the front end of the hollow plate, bolts for locking the adjusting plate on the hollow plate, pressure dividing blocks at the front end of the adjusting plate, and inserting cones on each pressure dividing block. A planting cylinder is provided at the top of the central block and the top of the hollow plate.

[0006] Furthermore, an arc plate is provided between adjacent hollow plate sidewalls, and a plurality of planting tubes are provided on the top of the arc plate.

[0007] Furthermore, the front end of the hollow plate is provided with a slot that matches the adjustment plate, and the two side walls of the adjustment plate are symmetrically provided with limiting rails that match the side walls of the slot.

[0008] Furthermore, the side wall of the hollow plate away from the central block is provided with a through hole that matches the bolt, and the adjusting plate is provided with a number of adjusting holes that match the bolt.

[0009] Furthermore, the insertion cone includes a stop and a cone body, and the center block and the pressure dividing block are both provided with insertion holes that pass through the cone body.

[0010] The beneficial effects of this utility model are as follows: By inserting cones to press the pressure blocks onto the protective net, the combined action of the central block and the cross-shaped pressure blocks, adjusting plates, and hollow plates expands the coverage area of ​​the protective net, effectively preventing local areas of the protective net from being blown away by strong winds. By planting vegetation in planting cylinder one and planting cylinder two, some rainwater will be absorbed or blocked by the vegetation during rain, reducing the scouring area and falling force of rainwater on the slope area, thus reducing the scouring capacity of rainwater on the slope and effectively reducing the amount of small coal mine impact roll-offs from the unstable surface of the slope. This can significantly reduce the impact on the stability of open-pit coal mine slopes and greatly improve the protective effect. Attached Figure Description

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] According to the appendix Figure 1 , 4 As shown: This utility model provides a slope stabilization mechanism for open-pit coal mining areas: it includes a protective net 1, and several stabilizing components 2 arrayed on the protective net 1. The stabilizing components 2 include a central block 3, and hollow plates 4 arranged in a cross pattern are provided on the four side walls of the central block 3. An adjusting plate 5 is slidably inserted into the front end of the hollow plate 4. A pressure-distributing block 7 is provided at the front end of the adjusting plate 5. Each pressure-distributing block 7 has a cone 8 inserted through it. The cone 8 includes a stop and a cone body. The central block 3 and the pressure-distributing blocks 7 are provided with insertion holes 14 through the cone body. Specifically, the stop is hammered to drive the cone body into the rock and soil of the slope in the open-pit coal mining area until the bottom of the stop is in contact with the top of the pressure-distributing block 7, thereby pressing the pressure-distributing blocks 7 arranged in a cross pattern onto the protective net 1.

[0020] As per the instruction manual Figure 1 , 2 As shown: Planting tube 1 9 is provided on the top of the central block 3 and the top of the hollow plate 4. An arc plate 10 is provided between the side walls of the adjacent hollow plate 4. Several planting tubes 2 11 are provided on the top of the arc plate 10. Specifically, planting soil is placed on planting tube 1 9 and planting tube 2 11, and vegetation is planted in planting tube 1 9 and planting tube 2 11. During rainy weather, some rainwater will be absorbed or blocked by the vegetation, effectively reducing the scouring area and falling force of rainwater on the slope area.

[0021] As per the instruction manual Figure 3 As shown: The hollow plate 4 is provided with bolts 6 for locking the adjusting plate 5. The front end of the hollow plate 4 is provided with a slot that matches the adjusting plate 5. The two side walls of the adjusting plate 5 are symmetrically provided with limiting rails 12 that match the side walls of the slot, which serve to limit the position of the adjusting plate 5. The side wall of the hollow plate 4 away from the center block 3 is provided with a through hole that matches the bolts 6. The adjusting plate 5 is provided with several adjusting holes 13 that match the bolts 6. Specifically, by matching the bolts 6 with the adjusting holes 13 at different positions, the extension length of the adjusting plate 5 can be adjusted, thereby adjusting the distance between the center block 3 and the pressure dividing block 7 to a suitable position.

[0022] The principle of this utility model

[0023] In use, by matching the bolts 6 with the adjustment holes 13 at different positions, the distance between the center block 3 and the pressure-distributing block 7 is adjusted to a suitable position. By chiseling the cone of the insert 8 into the rock and soil of the slope of the open-pit coal mining area until the bottom of the stop head is in contact with the top of the pressure-distributing block 7, the pressure-distributing block 7 can be pressed onto the protective net 1. Under the combined action of the center block 3, the pressure-distributing blocks 7 distributed in a cross shape, the adjustment plate 5, and the hollow plate 4, the coverage area of ​​the protective net 1 is effectively expanded, thereby effectively preventing the local area of ​​the protective net 1 from being blown away by strong winds. By planting vegetation in the planting cylinder 1 9 and the planting cylinder 2 11, some rainwater will be absorbed or blocked by the vegetation when it rains, effectively reducing the scouring area and falling force of rainwater on the slope area, thus reducing the scouring capacity of rainwater on the slope, thereby effectively reducing the amount of small coal pieces impacting and rolling off the surface of the unstable slope, which can fully reduce the impact on the stability of the open-pit coal mine slope and greatly improve the protection effect.
