Description

TECHNICAL FIELD

[0001] The utility model belongs to the mining technical field, specifically relates to a protection dam of high and steep slope area of mine. BACKGROUND

[0002] In the process of mining, due to the excavation and disturbance of mountain, high and steep slope area is often formed. These high and steep slope areas have great potential safety hazards and environmental impacts.

[0003] With the development of mining activities, the geological structure of high and steep slope becomes unstable, and geological disasters such as rock collapse and soil landslide are likely to occur. These disasters not only directly threaten the production activities of the mine, affect the mining progress and equipment safety, but also endanger the life safety of on-site workers.

[0004] In the past, the protection measures for high and steep slope area of mine are often simple and single. The common method is to set up some simple protective nets, however, the protective capacity of such protective nets is limited when facing large-scale rock collapse and large amount of soil landslide. Large volume of stones and large amount of loose soil may break through the interception of protective nets and directly rush to the surrounding area, causing serious damage.

[0005] At the same time, under weather conditions such as rainfall, rainwater will erode the slope, leading to soil and water loss and increasing the risk of landslide. Moreover, if the water flow formed by rainwater mixed with sand, gravel and other materials cannot be effectively treated, it will accumulate in the slope area, increasing the pressure of the slope and further increasing the possibility of geological disasters.

[0006] In addition, when stones and soil hit the protective facilities, the splashes produced may also cause harm to the surrounding environment and personnel. The traditional protective facilities often lack effective design in dealing with splashes, and cannot effectively slow down the speed and impact of splashes, nor can they change their movement direction, so as to reduce their harm.

[0007] Therefore, we propose a protection dam for high and steep slope area of mine, which effectively protects the high and steep slope area of mine and reasonably treats the water flow, maximally reduces the potential safety hazards and environmental impacts. CONTENT OF THE UTILITY MODEL

[0012] Further, the protection net is fixed on the mine high and steep slope by first bolt.

[0013] Further, the protection board bottom is provided with first mounting plate, and the first mounting plate is installed on the mine high and steep slope installation platform by second bolt.

[0014] Further, the support plate bottom is provided with second mounting plate, and the second mounting plate is installed on the mine high and steep slope installation platform by third bolt.

[0015] Further, the protection board side is formed with mounting groove, and the mounting groove is internally provided with mounting plate connected with the support plate.

[0016] Further, the buffer assembly includes arc hollow plate connected with the protection board, the arc hollow plate is internally provided with spring, the spring side is provided with arc movable plate, and the arc movable plate one end is connected with the anti-splashing board.

[0017] The utility model achieves the following technical effects:

[0018] When the mine high and steep slope area appears unstable conditions, such as rock collapse, soil landslide, the protective net first set on the slope can intercept large volume of stone and a large amount of loose soil, but part of the smaller stone and soil may break through the interception of the protective net, and these objects breaking through the protective net then impact on the protective plate, the protective plate bears the direct impact and transmits the impact force to the support plate connected with it, the support plate disperses and bears part of the impact force through the stable connection with the installation platform of the mine high and steep slope, so as to ensure the stability of the protective plate, at the same time, the anti-splashing plate hinged on one side of the protective plate can play a role when the splashing object impacts the protective plate, when the splashing object impacts the anti-splashing plate, the anti-splashing plate will produce certain deformation and displacement due to its L-shaped structure and buffer assembly, the buffer assembly will be compressed or stretched to absorb the energy of the splashing object, so as to slow down the speed and impact force of the splashing object. The L-shaped structure of the anti-splashing plate can also change the movement direction of the splashing object, so that it falls downward, reducing the influence on the surrounding area, in the case of rainfall or other water flow, the water flow enters the hollow cavity of the installation platform of the mine high and steep slope through the water inlet. The inclined filter plate in the water inlet can filter the water flow. The impurities in the water flow, such as sand, gravel and the like, will slide along the inclined surface and be discharged through the impurity discharge port due to the gravity and impact of the water flow when encountering the inclined filter plate, and the relatively clean water flow after filtration is gathered in the hollow cavity. When the water level reaches a certain height, the water flow is discharged through the drain pipe, so as to avoid the accumulation of water in the platform and reduce the pressure and potential damage to the protective dam structure.

[0027] The mine high and steep slope installation platform 10 is provided with a water inlet 6, an impurity discharge port 7 and a drain pipe 8 which are communicated with the hollow cavity of the mine high and steep slope installation platform 10, and the mine high and steep slope installation platform 10 is internally provided with an inclined filter plate 9 corresponding to the position of the impurity discharge port 7.

[0028] When the protective net 2 is installed, the protective net 2 is fixed on the mine high and steep slope through first bolts, and the arrangement can facilitate the installation and disassembly of the protective net 2.

[0029] When the protective plate 3 is installed, the protective plate 3 is provided with a first mounting plate 11 at the bottom, and the first mounting plate 11 is installed on the mine high and steep slope installation platform 10 through second bolts, and the arrangement facilitates the installation and disassembly of the protective plate 3.

[0030] When the support plate 4 is installed, the support plate 4 is provided with a second mounting plate 12 at the bottom, and the second mounting plate 12 is installed on the mine high and steep slope installation platform 10 through third bolts, and the arrangement facilitates the installation and disassembly of the support plate 4.

[0031] The protective plate 3 is provided with a mounting groove 13 on one side, and a mounting plate connected with the supporting plate 4 is arranged in the mounting groove 13, so that the supporting plate 4 can be mounted on the protective plate 3 to support, disperse and bear part of the impact force, thereby ensuring the stability of the protective plate 3.

[0032] The L-shaped splash-proof plate 5 is arranged as shown in the figure. Figure 2 When the rolling stone rolls due to gravity and obtains great inertia, the rolling stone will splash when colliding with the protective plate 3, and the splash-proof plate 5 arranged as shown in the figure can make the splashing rolling stone collide with the splash-proof plate 5, and the impact force can be reduced by the buffer assembly. Figure 2

[0033] The buffer assembly comprises an arc-shaped hollow plate 14 connected with the protective plate 3, a spring 15 arranged in the arc-shaped hollow plate 14, and an arc-shaped movable plate 16 arranged on one side of the spring 15 and connected with the splash-proof plate 5.

[0037] ​The working principle of the utility model is as follows: when the mine high and steep slope area appears unstable situation, for example, rock collapse, soil landslide, first, the protection net 2 arranged on the slope can preliminarily intercept the stone block of larger volume and a large amount of loose soil. But part of smaller stone block and soil can break through the interception of protection net 2, these objects breaking through the protection net 2 then impact on the protection plate 3. The protection plate 3 bears direct impact and transmits the impact force to the support plate 4 connected with it, and the support plate 4 disperses and bears part of the impact force through its firm connection with the installation platform 10 of mine high and steep slope, thereby ensuring the stability of the protection plate 3, at the same time, the anti-splashing plate 5 hinged on one side of the protection plate 3 can play a role when the splashing object impacts the protection plate 3. When the splashing object impacts the anti-splashing plate 5, the anti-splashing plate 5 can produce certain deformation and displacement due to its L-shaped structure and buffer assembly, and the buffer assembly can be compressed or stretched to absorb the energy of the splashing object, thereby slowing down the speed and impact force of the splashing object. The L-shaped structure of the anti-splashing plate 5 can also change the movement direction of the splashing object, so that it falls downward, reducing the influence on the surrounding area. In the case of rainfall or other water flow, the water flow enters the hollow cavity of the installation platform 10 of mine high and steep slope through the water inlet 6. The inclined filter plate 9 in the water inlet 6 can filter the water flow. The impurities in the water flow, such as sand, gravel, etc., will slide down along the inclined surface when encountering the inclined filter plate 9 due to the action of gravity and water flow impact, and be discharged through the impurity discharge port 7. The relatively clean water flow after filtration is gathered in the hollow cavity. When the water level reaches a certain height, the water flow is discharged through the drain pipe 8, thereby avoiding the accumulation of water inside the platform and reducing the pressure and potential damage to the protection dam structure. The drain pipe 8 can be connected to a suitable drainage channel or water collection facility to realize the orderly guidance and discharge of the water flow. In this way, the whole protection dam realizes effective protection of the mine high and steep slope area and reasonable treatment of the water flow through the synergistic effect of various components, thereby minimizing potential safety hazards and environmental impact.

[0038] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, which should also be considered as the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the art without special description and limitation.
