DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the related art, a method for repairing a high-level fracture space caused by mining by grouting includes the following steps:

[0031] Step 1: Based on the fracture characteristics of the key strata of overburden movement, collect the fracture distance and mining thickness of coal mining in the mining area by collecting the ground drill column data of each coal mining area;

[0032] Step 2: Use the key layer identification method to identify the position of the overburden key layer at each borehole, thereby determining the position of the main key layer;

[0033] Step 3: Determine the fracture form of the main key layer, delineate the water-conducting fracture area, and determine the use of horizontal directional drilling along the rock layer above and below the main key layer based on the coal seam burial depth and ground drilling conditions;

[0034] Step 4: After the drilling is completed, the spacing of the grouting holes is determined according to the fracture distance. The grouting holes are arranged in the area where the high-level separation zone has not yet formed a separation zone. Grouting is started at the ground grouting station. Large-particle slurry is pumped into the high-level separation zone. The grouting pressure is used to plug the cracks in the separation zone below the main key layer and the cracks in the lower part of the main key layer. Fine-particle slurry is pumped into the separation zone of the fracture zone and the slurry pressure is used to plug the cracks above the main key layer.

[0035] Step 5: First grout the separation zone. After the grouting of the separation zone is completed, continue to advance the working surface.

[0036] Step 6. Repeat Step 1-Step 5 until the mining is completed;

[0037] In Step 2, the key layer is determined by using KSPB software;

[0038] In Step 3, the fracture forms of the main key layer include "OX" fracture forms, where the "O"-shaped fracture forms a crack that penetrates from top to bottom, and the "X"-shaped fracture forms a crack that is closed at the top and open at the bottom.

[0039] In Step 3, the specific method of using horizontal directional drilling is as follows: the maximum development position of the high-level abscission zone is determined according to the formula for the water-conducting fracture zone, and a dual-level directional drilling operation is performed. After the horizontal section is leveled, the first horizontal directional drill hole is located in the fracture zone abscission zone, and the second horizontal directional drill hole is located in the high-level abscission zone.

[0040] The specific construction arrangement of the dual-horizontal directional drilling is as follows: both boreholes are drilled vertically from the ground. The first horizontal directional drilling hole is aligned above the main key layer so that the horizontal section is located 3-5 meters above the main key layer; the second horizontal directional drilling hole is aligned within the main key layer so that the horizontal section is located 30 cm below the main key layer. Each borehole is drilled from the stop line to the cutting direction, so that the horizontal section drilled can penetrate the entire working face.

[0041] In Step 4, the large particle slurry is a mixture of cement fly ash with a specific gravity of 1.4-1.6 and a mixture of 46 mm large particle aggregate (such as walnut shells) or a mixture of cement fly ash with a specific gravity of 1.3-1.5 and a mixture of 23 mm fiber-rich aggregate (such as cottonseed shells). The mixing ratio of large particle aggregate is 12 kg per 1 m of cement fly ash mixture, and the mixing ratio of fiber-rich aggregate is 12 kg per 1 m of cement fly ash mixture.

[0042] In Step 4, the fine particle slurry is a cement fly ash mixed slurry with a specific gravity of 1.11.3;

[0043] In Step 4, the specific method of grouting is:

[0044] Step 4.1. After the No. 2 horizontal directional drilling hole is arranged, a grouting pipe is arranged in the hole of the No. 2 horizontal directional drilling hole. The first grouting hole is located 40m from the cut hole. First, a mixture of cement and fly ash with a specific gravity of 1.4-1.6 is injected, mixed with 23mm large-particle aggregate. After continuous injection for 2 hours, if the grouting pressure reaches 0, a 46mm fiber-rich bone slurry is used instead.

[0045] The material is added into cement fly ash mixed slurry for grouting;

[0046] Step 4.2: Continue injecting the cement-fly ash slurry mixed with fiber-rich aggregate until the grouting pressure rises. Continue grouting with the cement-fly ash slurry mixed with large-particle aggregate. When the slurry pressure rises to 12 MPa, continue grouting with a fast-setting slurry mixed with cement and water glass. Continue grouting until the slurry pressure rises again.

[0047] Step 4.3: After the grouting of the high-position delamination area is completed, grouting of the fracture zone delamination area is carried out. Directly inject a cement fly ash mixed slurry with a specific gravity of 1.11.3. Stop grouting when the grouting pressure starts to rise.

[0048] Compared with the existing technology, this solution has the following beneficial effects: it can adapt to the determination of the main key layers of drilling and grouting plugging under dual-system mining conditions, can provide protection for mine prevention and control of water and gas leakage disasters, and its use method is reliable and practical.

[0049] Based on the influence of coal seam geological conditions and mining parameters on the development of water-conducting fracture zones in the main key strata, this method not only considers the distribution area of ​​the overburden water-conducting fracture zones, but also the influence of grouting materials and grouting methods on the sealing effect. It also ensures that the grouting rate matches the working face advancement speed. A comprehensive approach is adopted to address the fractures in the main key strata under dual-system mining. By grouting into the separation zone, the slurry pressure is used to seal all fractures in the key strata. This not only overcomes the difficulties of grouting with the grouting reduction method, but also ensures that the grouting rate matches various parameters such as working face advancement. In addition, it ensures the comprehensiveness of grouting and completely seals the "0-X" fractures. It is not only safe, reliable and practical, but also effectively reduces the degree of water and gas leakage and alleviates the occurrence of water and gas damage.

[0069] In addition, in order to achieve the above-mentioned purpose, a grouting method is provided for a concrete crack repair and sealing grouting device, comprising the following steps:

[0070] S1. Drill three holes in the cracked ground and secure them to the ground using four sets of mounting screws. Ensure that the two sets of first mounting holes and one set of second mounting holes correspond to the three sets of holes. Insert two sets of T-shaped connecting rods into the first mounting holes, allowing the telescopic airbag to enter the drilled holes. After insertion, secure the T-shaped connecting rods to the sealing connecting plate.

[0071] S2. Insert the vibrating rod through the second mounting hole into the corresponding hole.

[0073] Compared with the existing technology, the beneficial effect of this solution is: after drilling a hole with the same depth as the crack at the crack, the sealing connecting plate is installed on the ground of the crack, and the telescopic airbag and the vibrating rod are allowed to enter the drilled hole. By inflating the sealing airbag and the telescopic airbag, the crack in this section of grouting can be sealed, and the slurry can be injected into the crack through the telescopic grouting pipe. Since the crack in this section of grouting is sealed, the sealing slurry will enter each group of cracks, and the flow rate of the sealing slurry can be accelerated by the vibrating rod. When the crack is completely filled, the excess slurry moves upward and squeezes the trigger mechanism, and the grouting stops at this time to prevent the excess repair fluid from overflowing from the crack to the ground due to the narrowness of the crack in some positions, resulting in waste of repair slurry and inability to completely repair the crack.
