Generally, slope areas or slope areas generated by mine development are not suitable for the natural growth conditions of vegetation. Therefore, after the development of mines, the slope prevention of slope and the landscaping of surrounding vegetation are being planned.

On the other hand, open pit mines are exposed to the atmosphere after the mining is completed, unlike ordinary mines where mines should be formed for mining. Therefore, if left untouched, the slope surface will be devastated by erosion due to natural phenomena, and the acidic mining rock wastewater will be eluted, causing severe environmental pollution on the slope and the surrounding soil and river.

At present, in order to prevent collapse of the slope of the above-mentioned mine area, soil reinforcement is performed by using soil nail, rock bolt, etc. In order to prevent erosion due to slope erosion and erosion due to rain, And the slope surface is composed of a block mattress like a concrete block. Then, considering the environmental aspect, the vegetation activation method such as Rye soil, seed spraying, lawn planting is utilized.

However, the above-mentioned slope protection method is costly and not easy to construct, and it can not solve the pollution problem of the surrounding water quality due to the leakage of the acidic mining rock wastewater as it is, and the water and nutrients necessary for plant growth It is not possible to add enough nutrients to the plant, so that the planting is not slow or stabilized and the plants and seeds are damaged. In addition, nutrients and water must be supplied periodically to prevent vegetation or seed damage, There is also a problem that it takes.

Patent Document 1 (Registration No. 10-0944269) discloses a vegetation bag having a space formed therein; And a filling material which is formed by mixing culture soil, nutrients, neutralizing agent and moisturizing agent and filling the inside of the vegetation bag to form a vegetation base of vegetation or seed and neutralize harmful substances eluted into slope, And it is possible to record the degradation slope in an environmentally friendly way by helping the planting and growing of the vegetation for the greening and seeding by constructing the mat on the slope caused by the development of the mine. However, due to the contact of moisture and microorganisms and low tensile strength, Is very weak in durability.

1, an eco-friendly mat 100 for sloped surface recording in a mine area according to the present invention is a mattress fabric 10 in which a vegetable fiber yarn 11 is woven with a weft and a weft, a tensile strength of a vegetable fiber yarn 11 And a reinforcing layer formed on the vegetable fiber yarn 11 to improve antimicrobial resistance. The mat main body 10 may be formed as a double layer as long as there is no space, and as a double layer having a space enclosed with the inside of the mat. In case of a sac type, a separate culture soil may be filled in the inside of the mat main body 10.

The vegetable fiber yarn 11 is intended to maintain the soil on the inclined surface in a natural manner without altering the soil. The vegetable fiber yarn 11 is made of coconut fiber yarn (made of coconut husk) or Shinseo's yarn (Shinseo Ran's skin) (A plurality of fiber yarns are twisted), or the two strands 11-1 and 11-2 may be twisted in a rope shape as shown in FIG. 2B, and the four strands 11-1, 11- 2,11-3,11-4) may be twisted into a rope shape. Of course, the vegetable fiber yarn 11 is not limited thereto and can be made of various vegetable materials and structures.

Since the vegetable fiber yarn 11 can be used in various thicknesses, it is not limited to a specific value. For example, the thickness of one strand may be 3 to 10 mm.

The reinforcing layer can be classified into one that satisfies tensile strength and antimicrobial antimicrobial simultaneously, that has only improved tensile strength, and has improved antimicrobial resistance.

The improvement of tensile strength is made by a tensile strength agent made from latex. The improvement of antibacterial property is made by Cooper sulfate and the solvent type is by colloidal (Siber Colloidal) , A nano-particle size (5 to 10 nm)], and a food additive (for example, a bactericide for food additives containing acetic acid as a main component: Blosen (trade name)).

As the tensile strength agent, a latex stock solution can be used, and a latex diluted solution mixed at a weight ratio of 1: 4 to 8 is preferably used as the latex stock solution: diluted solution (water, etc.).

It is known that latex is a liquid of rubber tree containing a large amount of rubber components and thus has excellent tensile strength. Durability is improved by interrupting the contact of water with vegetable fiber yarn (11). When the dilution liquid is less than 4 parts by weight, If the weight ratio is exceeded, the tensile strength effect is weak.

In addition to latex, tensile strength agents can be used with rubber systems that function more than or equal to latex.

The mixture of colloid and food additive (colloid and food additive in 1: 1 ratio by weight), copper sulfate and colloid in solvent type (mixture of 1: 1 by weight) ), A mixture of copper sulfate and food additives (1: 1 mixture of weight fertilizer), copper sulfate and solvent type, a mixture of colloids and food additives (three materials mixed in equal weight ratios).

Copper sulfate is a powder (all products available in the market can be used), which is excellent in antibacterial and antimicrobial properties due to strong irritation, and can be used to dilute the copper sulfate, .

Dilution of copper sulfate diluted solution is 1: 2,700 ~ 3,300, preferably 1: 3,000, and the concentration is low when the concentration of copper sulfate (powder): diluted solution (distilled water, water) is in a weight ratio and the antimicrobial antimicrobial effect is weak or strong side effects Cause.

Solvent-type colloids are widely known to have antibacterial and antimicrobial properties.

Food additive is a disinfectant whose main ingredient is peracetic acid and is used to remove bacteria and fungi of fruits and vegetables and sterilizes by oxidizing the extracellular membrane of microorganisms.

The reinforcing layer according to the present invention has tensile strength and antimicrobial antimony compound reinforcing layer 12 (FIG. 3), tensile strength reinforcing layer 13 (FIG. 4), antimicrobial antimony reinforcing layer 14 5), a tensile strength reinforcing layer 15-1 and an antimicrobial antimony-reinforcing layer 15-2 are stacked.

The reinforcing layer is formed by spraying, immersion or the like of a tensile strength agent and an antimicrobial agent.

As shown in FIG. 3, the tensile strength and the antibacterial and antimicrobial composite reinforcing layer 12 according to the present embodiment are mixed with a tensile strength agent and an antibacterial antimicrobial agent to coat the surface of the vegetable fiber yarn 11 (Which may penetrate into the yarn 11).

The thickness of the coating layer is preferably from 1 to 2.7 mu m, and if the thickness is out of the above range, the function of the reinforcing layer is weak and the productivity is poor.

The tensile strength agent and the antimicrobial antimicrobial agent are preferably mixed at the same weight ratio in order to obtain the tensile strength and the antibacterial antimicrobial effect at the same time. Of course, the mixing ratio may vary depending on the construction site and the like. For example, (For example, 55 to 70% by weight of an antimicrobial antifouling agent and 30 to 45% by weight of a tensile strength agent) than the tensile strength agent.

Antibacterial antimicrobial copper sulfate, solvent type colloid and food additive can be used more than one, and when two or more are used, they can be mixed in the same weight ratio or can be appropriately adjusted within the entire mixing range.

The present embodiment has an advantage that two good effects of tensile strength and antibacterial antimicrobial can be derived together.

As shown in FIG. 4, the tensile strength reinforcing layer 13 according to the present embodiment is formed by coating a tensile strength agent (latex diluent). That is, it does not use an antibacterial antimicrobial agent. Although it has a weak antibacterial antimicrobial effect, it has a weak antibacterial antimicrobial effect because it blocks the contact between vegetable fiber fiber 11 and water.

As shown in FIG. 5, the antimicrobial antimony-reinforcing layer 14 according to this embodiment is formed by coating of an antibacterial antimicrobial agent (copper sulfate and solvent-type colloid and at least one of food additives). That is, although the tensile strength agent is not used, the tensile strength reduction rate of the vegetable fiber yarn 11 is limited, but the bacterial and microorganisms are prevented from contacting the vegetable fiber yarn 11, thereby reducing the tensile strength reduction rate.

6, the laminated reinforcing layer 15 according to the present embodiment is formed by laminating a tensile strength reinforcing layer 15-1 (formed by coating with a latex diluent, and an antimicrobial antimony reinforcing layer The tensile strength reinforcing layer 15-1 and the antimicrobial antimony-reinforcing layer 15-2 are formed in the order of 15-2 and 15-2, respectively. Can be reversed.

As in the case of Example 1, there is an advantage that two good effects of tensile strength and antibacterial antimicrobial can be derived together.

Antimicrobial antimicrobial effect is weak, but it blocks the contact between vegetable fiber yarn (11) and water, and it shows weak antibacterial effect.

The method of stabilizing slope greening in a mine area using an environmentally friendly mat for mine area slope recording according to the present invention comprises steps of flattening slopes (slopes, slopes, etc.) to be applied to the mats of the present invention, Anchoring, etc.).

The step of applying the mat may include applying the mat 100 to the mat 100 by previously planting the green seed, setting the mat 100 on the slope, applying the green seed or vegetation to the mat 100 by vegetation or spraying, And the like.

Of course, it is also possible to use green seeds of surrounding soil without using any other green seeds.

Hereinafter, a specific embodiment of the present invention will be described.
