Description

Technical Field

[0001] This utility model relates to the field of mine ecological restoration technology, specifically to an ecological grass mat for abandoned mines. Background Technology

[0002] Long-term mining activities have severely damaged surface vegetation. Large amounts of vegetation have been removed or died due to mining activities, and the original vegetation layer covering the ground has almost completely disappeared. Simultaneously, excavation and blasting operations during mining have damaged the soil structure, disrupting the original bonds between soil particles, making the soil loose and infertile. These changes have led to widespread soil erosion. Every time it rains, large amounts of soil are washed away with rainwater, not only wasting soil resources but also potentially triggering geological disasters such as mudslides, threatening the surrounding ecological environment and the safety of residents.

[0003] Traditional mine remediation methods have many drawbacks. For example, some methods require lengthy vegetation cultivation and soil improvement processes, resulting in long remediation cycles during which the ecological environment continues to deteriorate, making it difficult to see rapid remediation results. Some remediation technologies rely on expensive equipment and materials, leading to high costs that many mining companies cannot afford. Furthermore, some methods fail to adequately consider the unique geological and environmental conditions of mines, resulting in poor remediation outcomes and an inability to effectively restore vegetation and improve the ecological environment. Therefore, exploring an efficient, economical, and adaptable remediation solution is of paramount importance. Utility Model Content

[0004] In view of the shortcomings of existing ecological restoration methods, such as long restoration cycle, poor restoration effect and high cost, this utility model provides an ecological grass mat for abandoned mines that can reduce the restoration cycle, achieve good restoration effect and low cost.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An ecological grass mat for abandoned mines includes a main body consisting of a non-woven fabric layer, a first connecting layer, a soil arrangement component, and a second connecting layer, and several anchor rods. The first connecting layer includes a breathable net and several storage frames. Two storage frames can be connected together, and each storage frame has several slots evenly distributed along its inner wall. The breathable net covers the non-woven fabric layer, and the bottom of each storage frame is connected to the breathable net, while its sides are connected to adjacent storage frames. The soil arrangement component engages with the storage frames via the slots. The second connecting layer is composed of a mixture of soil and grass seeds and is placed inside the storage frames. The anchor rods pass through the main body of the grass mat and connect to the mine soil.

[0007] Furthermore, the soil arrangement component is composed of interlocking card plates, with each card plate engaging with a corresponding slot. The card plates form a grid shape, and their engagement with the slots in the storage frame enhances the structural stability of the grass mat. The partitioned design ensures adequate airflow and space for plant growth, while also facilitating the even distribution of grass seeds and soil, thus improving seed germination and seedling survival rates. The card plate component is also highly flexible and can be adjusted according to actual needs.

[0008] Furthermore, the card plate assembly is equipped with locking blocks that mate with the card slots, and has several strip-shaped through holes evenly distributed in the middle for assembly. The card plate assembly is assembled through the strip-shaped through holes, and connected by the locking blocks engaging with the card slots. The engagement of the locking blocks with the strip-shaped through holes ensures that the card plate assembly can be securely assembled and tightly connected to the card slots of the storage frame. This not only simplifies the installation process and improves construction efficiency, but also enhances the stability and flexibility of the structure, facilitating adjustments to the mesh structure according to the actual terrain.

[0009] Furthermore, the card plate assembly includes a mating A plate and a B plate, wherein the strip-shaped through hole of the A plate is located at the top, and the strip-shaped through hole of the B plate is located at the bottom. The card plate assembly is connected through the mating of the A plate and the B plate, resulting in a simple structure and convenient use.

[0010] Furthermore, the mesh diameter of the breathable net is 1-3 mm. This 1-3 mm mesh diameter ensures adequate airflow and water penetration, which is beneficial for plant root respiration and growth, while preventing soil particle loss. It also maintains the stability and durability of the grass mat's internal structure, helps improve seed germination and seedling survival rates, promotes rapid vegetation cover, and accelerates the ecological restoration process. In addition, this mesh size effectively prevents larger debris from entering the grass mat, reducing external interference with vegetation growth and enhancing the overall restoration effect.

[0011] Furthermore, the storage frame is rectangular, with connecting plates on two adjacent sides and connecting rings on the other two adjacent sides. When two storage frames are combined, the connection is achieved through the cooperation between the connecting plates and the connecting rings. The rectangular storage frames, when combined, achieve a stable connection through the cooperation of the connecting plates and connecting rings, which not only simplifies the laying process and improves construction efficiency, but also enhances the stability and adaptability of the structure, ensuring that the straw mat adheres tightly to different terrains and preventing displacement. The standardized connection method also allows for flexible adjustment of the size and shape of the straw mat, facilitating its laying, reducing labor costs and maintenance, and making it more economical and practical.

[0012] Furthermore, the bottom of the storage frame is equipped with a connecting post that works with the breathable mesh, and the connecting post is also equipped with a barb. After the connecting post passes through the breathable mesh, the barb on the connecting post hooks onto the breathable mesh, achieving a stable connection between the two. The cooperation between the connecting post and the barb not only simplifies the installation process and ensures a firm connection between the storage frame and the breathable mesh, but also enhances the stability of the overall structure, effectively preventing displacement or separation during construction or subsequent use.

[0013] How to use:

[0014] The first step in laying the grass mat is to clean and level the surface of the abandoned mine. Remove stones, debris, and garbage to prevent these materials from affecting the adhesion of the mat to the ground and the growth of the plants. After cleaning and leveling, place the prepared grass mat on the treated mine surface and secure it with anchor bolts along its edges. Anchor bolts can also be added to the middle of the mat as needed to ensure stability in the mine soil. The soil will then be stabilized and repaired through the germination and growth of the grass seeds. The anchor bolts can be made of iron, wood, or plastic, with a length of 10-20 cm and a diameter of 0.1 cm. They are inserted into the mine soil at intervals of 20-30 cm to ensure a tight fit between the grass mat and the ground, preventing it from being blown away by wind or washed away by rain.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] 1. This utility model comprises a grass mat body consisting of a non-woven fabric layer, a first connecting layer, a soil arrangement component, and a second connecting layer, used in conjunction with anchor bolts. It can not only be quickly laid on the cleaned and leveled surface of abandoned mines, but also effectively promote vegetation restoration and reduce the risk of soil erosion. The breathable net and storage frame structure in the first connecting layer effectively fix the soil in sections, while the soil arrangement component facilitates the even distribution of grass seeds and soil, helping to improve seed germination rate and seedling survival rate. The overall design of the grass mat allows vegetation to be established in a short time, accelerating the ecological restoration process of the mine surface and shortening the restoration cycle. Furthermore, due to the use of a relatively simple structure and economical materials, the restoration cost is significantly reduced.

[0017] 2. The soil arrangement component of this utility model consists of a card plate assembly. The card plate assembly is connected to the card slot of the storage frame through card blocks. There is a strip-shaped through hole in the middle for the combination between card plates. This design enhances the structural stability of the grass mat, ensures air circulation and plant growth space, facilitates the uniform distribution of grass seeds and soil, improves seed germination rate and seedling survival rate, facilitates installation and flexible adjustment to adapt to different terrain requirements, improves construction efficiency and restoration effect, promotes rapid vegetation recovery, and accelerates the ecological restoration of abandoned mines.

[0018] 3. This utility model of breathable netting ensures good air circulation and water penetration, promotes plant root growth, prevents soil erosion, improves seed germination rate and seedling survival rate, and blocks interference from large debris; the storage frame is rectangular, and a stable connection is achieved through connecting plates and connecting rings, which simplifies the laying process, enhances structural stability, adapts to different terrains, prevents displacement, and allows for flexible adjustment of the size and shape of the straw mat, reducing labor costs and maintenance difficulty; after the connecting post at the bottom of the storage frame passes through the breathable netting, it uses barbs to hold the breathable netting, ensuring a firm connection and preventing displacement or separation during construction or use.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Example 1: An ecological grass mat for abandoned mines includes a grass mat body composed of a non-woven fabric layer, a first connecting layer 2, a soil arrangement component 3, and a second connecting layer 4, and several anchor rods; the first connecting layer 2 includes a breathable net 21 and several storage frames 22, in which two storage frames 22 can be connected together, and several slots 23 are evenly provided along the inner wall of the storage frames 22; the breathable net 21 covers the non-woven fabric layer, the bottom of the storage frame 22 is connected to the breathable net 21, and the sides are connected to adjacent storage frames 22; the soil arrangement component 3 cooperates with the storage frames 22 through the slots 23; the second connecting layer 4 is composed of a mixture of soil and grass seeds, and the soil and grass seeds are evenly filled into the storage frames 22 respectively; the anchor rods pass through the grass mat body and are connected to the mine soil.

[0026] The first step in laying the grass mat is to clean and level the surface of the abandoned mine. Remove stones, debris, and garbage to prevent these materials from affecting the adhesion of the mat to the ground and the growth of the plants. After cleaning and leveling, place the prepared grass mat on the treated mine surface and secure it with anchor bolts along its edges. Anchor bolts can also be added to the middle of the mat as needed to ensure stability in the mine soil. The soil will then be stabilized and repaired through the germination and growth of the grass seeds. The anchor bolts can be made of iron, wood, or plastic, with a length of 10-20 cm and a diameter of 0.1 cm. They are inserted into the mine soil at intervals of 20-30 cm to ensure a tight fit between the grass mat and the ground, preventing it from being blown away by wind or washed away by rain.

[0027] Example 2: Unlike Example 1, the soil arrangement component 3 is composed of card plate components 31 assembled together, with each card plate component 31 engaging with a corresponding slot 23. The soil arrangement component 3, with its card plate components 31 forming a continuous grid shape, engages with the slots 23 of the storage frame 22. This enhances the structural stability of the grass mat, and the partitioned design ensures air circulation and sufficient space for plant growth. It also facilitates the even distribution of grass seeds and soil, contributing to improved seed germination and seedling survival rates. The card plate components 31 can be adjusted according to actual needs, offering high flexibility.

[0028] The storage frame 22 is rectangular, with connecting plates 221 on two adjacent sides and connecting rings 222 on the other two adjacent sides. When two storage frames 22 are combined, the connection is achieved through the cooperation between the connecting plates 221 and the connecting rings 222. This rectangular combination of storage frames 22, with the connecting plates 221 and connecting rings 222, provides a stable connection, simplifying the laying process, improving construction efficiency, and enhancing the stability and adaptability of the structure. It ensures the grass mat adheres tightly to different terrains, preventing displacement. The standardized connection method also allows for flexible adjustment of the grass mat's size and shape, facilitating laying, reducing labor costs and maintenance, and making it more economical and practical.

[0029] The storage frame 22 has a connecting post 223 at its bottom that works with the breathable mesh 21, and the connecting post 223 is also equipped with a barb 224. After the connecting post 223 passes through the breathable mesh 21, the barb 224 on the connecting post 223 hooks onto the breathable mesh 21, achieving a stable connection between the two. The cooperation between the connecting post 223 and the barb 224 not only simplifies the installation process and ensures a firm connection between the storage frame 22 and the breathable mesh 21, but also enhances the stability of the overall structure, effectively preventing displacement or separation during construction or subsequent use.

[0030] Example 2: Unlike Example 1, the card plate assembly 31 is provided with a locking block 311 that mates with the locking slot 23, and a plurality of strip-shaped through holes 312 evenly distributed in the middle for assembly. The card plate assembly 31 is assembled through the strip-shaped through holes 312, and the card plate assembly 31 is connected by the locking block 311 engaging with the locking slot 23. Through the engagement of the locking block 311 and the strip-shaped through holes 312 in the card plate assembly 31, the card plate assembly 31 can be stably assembled and tightly connected to the locking slot 23 of the storage frame 22. This not only simplifies the installation process and improves construction efficiency, but also enhances the stability and flexibility of the structure, making it easy to adjust the mesh structure according to the actual terrain.

[0031] The clamping plate assembly 31 includes a mating A plate 313 and a B plate 314, wherein the strip-shaped through hole 312 of the A plate 313 is located at the top, and the strip-shaped through hole 312 of the B plate 314 is located at the bottom. The clamping plate assembly 31 is connected through the mating of the A plate 313 and the B plate 314, and has a simple structure and is easy to use.

[0032] The permeable mesh 21 has a mesh diameter of 1-3 mm. This 1-3 mm mesh diameter ensures adequate airflow and water penetration, which is beneficial for plant root respiration and growth, while preventing soil particle loss. It also maintains the stability and durability of the grass mat's internal structure, helps improve seed germination and seedling survival rates, promotes rapid vegetation cover, and accelerates the ecological restoration process. Furthermore, this mesh size effectively prevents larger debris from entering the grass mat, reducing external interference with vegetation growth and enhancing the overall restoration effect.
