[0002] In the process of underground mining, water inrush from the shaft wall is a common and serious disaster. It not only interrupts the normal production process, but also threatens the life safety of underground personnel and the normal operation of equipment.

[0003] Traditional treatment methods are often time-consuming, resource-consuming and ineffective. This situation is more prominent in underground mining environments such as coal mines and metal mines, especially in shafts constructed using the freezing method. When the frozen wall melts, water from the aquiferous strata may flow into the shaft through construction joints or weak parts of the shaft wall, causing water inrush accidents. Traditional methods are difficult to effectively control water inrush in a timely manner, which will aggravate the impact of disasters. Therefore, in view of the underground mining environment and water inrush, it is very necessary to develop a method and device that can respond quickly and efficiently control water inrush from the shaft wall.

Detailed implementation mode

[0024] The present invention discloses a rapid treatment system for water inrush in a mine shaft wall, which can achieve rapid water plugging and improve the emergency disposal ability for water disaster treatment.

[0025] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0026] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0027] Next, refer to Figure 1 and Figure 2 to describe the rapid treatment system for water inrush in the mine shaft wall in the embodiments of the present invention.

[0028] The embodiments of the present application disclose a rapid treatment system for water inrush in a mine shaft wall, including: a double-fluid grouting machine 1, a mixer 2, a high-pressure rubber hose for the mixing section 3, a grouting tee 4, and a water-stop casing 5 connected in sequence behind the double-fluid grouting machine 1.

[0029] Among them, the double-fluid grouting machine 1 has 2 slurry outlets, which are respectively communicated with the first slurry inlet hole and the second slurry inlet hole of the mixer 2 through the first slurry outlet pipe 11 and the second slurry outlet pipe 12. The cement slurry in the first slurry outlet pipe 11 and the sodium silicate slurry in the second slurry outlet pipe 12 are mixed at the mixer 2; a pressure relief valve 8 is installed on the mixer 2, and when the pressure in the mixer 2 is greater than the set pressure, it is relieved through the pressure relief valve 8; one end of the high-pressure rubber hose for the mixing section 3 is communicated with the slurry outlet hole of the mixer 2, and the other end is communicated with the water-stop casing 5 through the grouting tee 4. The mixed slurry entering the high-pressure rubber hose for the mixing section 3 from the mixer 2 is fully mixed and quickly reacts in the high-pressure rubber hose for the mixing section 3, so that a paste-like slurry is formed at the outlet end of the high-pressure rubber hose for the mixing section 3. The paste-like slurry is pressed into the water inrush point 30 of the shaft wall 9 through the water-stop casing 5 to quickly plug the water inrush point 30.

[0030] In the prior art, the technical solution of using grouting plugging method to plug the water inrush point 30 on the shaft wall 9 has the technical problem that the injected slurry is easily diluted and washed away by the flowing water. The main reasons for the above technical problems are that the slurry is relatively thin as a whole when injected, and there is still a period of time before solidification. At the same time, the water flow pressure is large, which easily washes away the slurry, and the solidification environment of the thin slurry is poor.

[0031] The rapid treatment system for water inrush in the mine shaft wall in this embodiment effectively solves the above technical problems by installing a high-pressure rubber hose 3 in the mixing section between the double-fluid grouting machine 1 and the water-stop casing 5. Specifically, by installing the high-pressure rubber hose 3 in the mixing section, the just-mixed slurry can fully mix and react in the high-pressure rubber hose 3 in the mixing section to form a paste-like slurry, and the paste-like slurry is used to plug the water inrush point 30 on the shaft wall 9. The paste-like slurry has the characteristics of high anti-washability, stable structure, short solidification time, and is not easily washed away by flowing water, and can effectively solve the problems that the currently injected slurry is easily washed away by flowing water and is not easy to solidify.

[0032] In some embodiments, the length of the high-pressure rubber hose 3 in the mixing section is determined according to the formula: It is determined that in the formula, L is the length of the high-pressure rubber hose 3 in the mixing section (unit: m), t is the solidification time of the mixed slurry (unit: s), v is the flow rate of the double-fluid grouting machine 1 (unit: L / s), d is the diameter of the high-pressure rubber hose 3 in the mixing section (unit: m). When the diameter and flow rate are determined, the solidification time of the mixed slurry is proportional to the length of the high-pressure rubber hose, that is, the longer the solidification time of the mixed slurry, the longer the length of the high-pressure rubber hose, and the shorter the solidification time, the shorter the length of the high-pressure rubber hose.

[0033] According to the above formula, the maximum effective length of the high-pressure rubber hose 3 in the mixing section can be effectively calculated. Within the maximum effective length, it can be ensured that the mixed slurry will not solidify in the high-pressure rubber hose 3 in the mixing section and can make the mixed slurry fully mix and react to form a paste-like slurry.

[0034] In the actual construction environment, there are various influencing factors, which will slow down the construction progress, resulting in the paste-like slurry not being able to be transported to the water inrush point 30 within the calculated time, and then causing the paste-like slurry to solidify in the rubber hose, resulting in hose blockage. In order to avoid this situation, when arranging the high-pressure rubber hose 3 in the mixing section, the actual length of the high-pressure rubber hose 3 in the mixing section is made less than the calculated length to leave enough construction margin for construction.

[0035] For example: Select the cement type as P.O42.5, the modulus M of sodium silicate is 3.0, the concentration of sodium silicate is 40 Be′ (Be′ is Baumé degree), the water-cement ratio of the cement slurry is 0.6:1, and the volume ratio of the cement-sodium silicate slurry is 1:0.5. The setting time of the cement-sodium silicate double slurry is 34 seconds. Select a grouting pump with a pump flow rate of 16 L / min and a high-pressure rubber hose 3 with a diameter of 38 mm for the mixing section. The maximum length of the high-pressure rubber hose 3 in the mixing section calculated according to the formula is 8 meters. Considering the construction complexity and for safety reasons, the actual length of the high-pressure rubber hose 3 in the mixing section is determined to be 5 m.

[0036] In some embodiments, a high-pressure ball valve 6 is installed on the water-stop casing 5. The grouting tee 4 is connected to the water-stop casing 5 through the high-pressure ball valve 6, and the mixed slurry enters the water-stop casing 5 through the high-pressure ball valve 6. By setting the high-pressure ball valve 6 as a control valve to control the grouting on and off.

[0037] In some embodiments, pressure gauges 7 are provided on both the double-fluid grouting machine 1 and the grouting tee 4 for observing the grouting pressure.

[0038] In some embodiments, a pressure relief valve 8 is also installed on the grouting tee 4. When the pressure in the grouting tee 4 is greater than the set pressure, it is relieved through the pressure relief valve 8 to prevent damage to the grouting tee 4 caused by excessive slurry pressure.

[0039] The present invention also proposes a rapid treatment method for water inrush in a mine shaft wall, including: S1. Determine the water inrush point 30 on the shaft wall 9; S2. Select grouting materials; S3. Arrange a plurality of drill holes 20 around the water inrush point 30 and bury water-stop casings 5 in each drill hole 20; S4. Install a high-pressure ball valve 6 on each water-stop casing 5 and conduct a pressure resistance test on each high-pressure ball valve 6. After the test is completed, clean the grouting drill holes 20 in the high-pressure ball valve 6; S5. Select any drill hole 20 below the water inrush point 30 to install the rapid treatment system for water inrush in the mine shaft wall and conduct a water pressure test; S6. After the water pressure test is passed, use the rapid treatment system for water inrush in the mine shaft wall to grout and quickly seal the water inrush point 30; S7. If the sealing is ineffective, it is necessary to clean all the drill holes 20 and re-select another drill hole 20 below the water inrush point 30 to repeat steps S5 and S6.

[0040] By treating the water inrush in the shaft wall according to the above method, the water inrush point 30 on the shaft wall 9 can be quickly and effectively sealed, and the impact caused by the water inrush can be minimized to the greatest extent.

[0041] In some embodiments, grouting using the rapid treatment system for water inrush from a mine shaft wall includes the following: The grouting process adopts a pressure of 2-3 times the water pressure at the current water burst point 30, thick slurry, flow limiting, and intermittent grouting. Among them, when the slurry continues to emerge from the water burst point 30 and becomes thick, intermittent grouting begins, and the time of intermittent grouting is less than the initial setting time of the mixed slurry in the mixing section high-pressure hose 3; during grouting, if the borehole 20 and the water burst point 30 continue to emerge slurry, the high-pressure ball valve 6 of each borehole 20 is closed one by one, and when there is no more slurry flowing out of the water burst point 30 and the grouting pressure reaches the designed grouting pressure, the grouting operation is stopped.

[0042] In some embodiments, the water pressure test includes: pressurizing the selected borehole 20 with water and keeping the high-pressure ball valves 6 of the remaining boreholes 20 open, observing the water conduction conditions of each borehole 20 and the water burst point 30, and proceeding to the next step after all or part of the water is conducted.

[0043] In some embodiments, the installation of a rapid control system for water inrush from a mine shaft wall includes: calculating the length of a mixing section high-pressure hose based on the setting time of the grouting material, the flow rate of a dual-liquid grouting machine, and the diameter of the mixing section high-pressure hose; and installing a rapid control system for water inrush from a mine shaft wall equipped with a mixing section high-pressure hose.

[0044] In some embodiments, selecting the grouting material includes: selecting cement-water glass double grout as the grouting material and determining the setting time of the grouting material.

[0045] Furthermore, in the selection of grouting materials, cement-water glass double slurry is used, wherein the cement model is P.O42.5, the modulus M of water glass is 3.0, and the concentration of water glass is 40Be′ (Be′ is Baume degrees). In addition, the water-cement ratio of cement slurry can be 1:1 or 0.6:1, and the volume ratio of cement-water glass slurry can be 1:0.5 or 1:1. According to the combination of different water-cement ratios and volume ratios, cement-water glass double slurries with different setting times can be prepared, specifically: when the water-cement ratio of cement slurry is 0.6:1 When the volume ratio of cement-water glass slurry is 1:0.5, the setting time is 34 seconds; when the volume ratio is 1:1, the setting time is 67 seconds; when the water-cement ratio of cement slurry is 0.8:1: when the volume ratio of cement-water glass slurry is 1:0.5, the setting time is 42 seconds; when the volume ratio is 1:1, the setting time is 92 seconds; when the water-cement ratio of cement slurry is 1:1: when the volume ratio of cement-water glass slurry is 1:0.5, the setting time is 52 seconds; when the volume ratio is 1:1, the setting time is 112 seconds.

[0046] According to different actual working conditions, the above-mentioned cement-sodium silicate double slurry with different ratios can be selected. For example, when the actual working conditions require plugging the current water inrush point 30 in the shortest time, the cement-sodium silicate double slurry with a water-cement ratio of 0.6:1 and a volume ratio of cement-sodium silicate slurry of 1:0.5 can be selected. The cement-sodium silicate double slurry under this ratio has the shortest setting time and can plug the water inrush point 30 in the shortest time. When, under the actual working conditions, it is impossible to install short high-pressure rubber hoses in the construction environment and only long high-pressure rubber hoses are allowed to be arranged, the cement-sodium silicate double slurry with a long setting time in the ratio can be adopted. For example, the cement-sodium silicate double slurry with a water-cement ratio of 1:1 and a volume ratio of 1:1 is adopted. Its setting time is as long as 112 seconds. When using a grouting pump with a pump flow rate of 16 L / min and a high-pressure rubber hose 3 with a diameter of 38 mm in the mixing section, the maximum length of the high-pressure rubber hose in the mixing section can reach 26.76 m, which can fully meet the requirements of the working conditions.

[0047] In some embodiments, the arrangement of the boreholes 20 around the water inrush point 30 includes: taking the water inrush point 30 as the center, at the same distance, at least 4 boreholes 20 are arranged around the water inrush point 30. Select any one of the boreholes 20 below the water inrush point 30 as the grouting hole, and the remaining boreholes 20 are used as guiding holes and pressure relief holes to ensure the safety and stability of the grouting process.

[0048] In some embodiments, step S3 specifically includes: arranging a plurality of boreholes 20 around the water inrush point 30, and the depth of the boreholes 20 is less than the thickness of the shaft wall 10 cm; burying a water stop casing 5; extending the boreholes 20 in the water stop casing 5, and the depth of the extended boreholes 20 enters the surrounding rock layer 10 by not less than 1 m. When drilling the boreholes 20 for the first time, avoid directly drilling through the shaft wall 9 to prevent the water flow in the shaft wall 9 from flowing out through the boreholes 20 and making it impossible to smoothly bury the water stop casing 5.
