Description

Technical Field

[0001] The present application relates to the field of mine restoration technology, and more specifically, to a treatment device and system for continuous water inrush. Background Art

[0002] During the mining process, vertical shaft drilling is required in complex strata with developed groundwater and fissures. These abandoned mines often have the hidden danger of continuous water inrush. These water inrushes come from the groundwater bodies in the abandoned mine areas. The changes in their flow and water quality have caused serious impacts on the environment, such as soil subsidence, ground collapse, soil erosion, etc.

[0003] If there is a sudden water gushing on the working face, the traditional method of dealing with water gushing in abandoned mines often uses an underground drainage system, but there are problems such as low efficiency, high cost, and difficult maintenance. The construction plan for treating large water gushing on the working face is usually to use concrete to construct a grouting pad on the working face. When constructing the grouting pad, it is necessary to drain the gushing water on the working face and the water dripping on the well wall in time, dig a pump nest at the bottom of the well, and use the height difference of the pump nest to allow the gushing water on the working face and the water dripping on the well wall to flow into the pump nest and be discharged by the submersible pump. This drainage method often causes sand and gravel in the concrete to flow into the pump nest along with the gushing water on the working face and the water dripping on the well wall, increasing the failure rate of the submersible pump, reducing the concrete strength of the grouting pad, and posing a safety hazard to the treatment of water gushing in the wellbore.

[0004] In summary, the existing spring water treatment process has technical problems such as low efficiency, high cost, difficult maintenance and potential safety hazards. Utility Model Content

[0030] In a first aspect, the present application provides a device for treating continuous water inflow, such as Figure 1 As shown, Figure 1 It is a structural schematic diagram of a device for treating continuous water inflow in an embodiment of the present application.

[0031] A device for treating continuous water inflow, used for treating a vertical shaft 1, comprises a dosing unit, a drainage unit, a water quality detection unit and a gas collection system 10:

[0032] The dosing unit comprises a plurality of dosing devices and dosing pipes, wherein the dosing devices are filled with limestone 3 and an organic layer 2, one end of the dosing pipe is connected to the dosing device, and the other end extends into the vertical shaft 1;

[0033] A drainage unit, comprising a water collection enclosure 7 and a drainage pipe 8, wherein the water collection enclosure 7 surrounds and covers the opening of the shaft 1, and the drainage pipe 8 is connected to the water collection enclosure 7;

[0034] A water quality detection unit connected to the drainage pipe 8;

[0035] The gas collection system 10 is connected to the water collection enclosure 7 .

[0036] The embodiment of the present application relies on the vertical shaft 1 to install a treatment device for continuous water gushing, and directly treats the gushing water on-site through the vertical shaft 1, avoiding the cumbersome construction of reaction facilities and drainage processes in traditional methods, improving the treatment efficiency, reducing the treatment cost, and being highly efficient and economical; through the dosing unit treatment measures, the organic layer 2 is used to reduce the sulfate in the wastewater, and the limestone 3 is used to adsorb suspended matter, which can effectively reduce the pollution of the surrounding environment by abandoned mines; the treatment device can continuously treat the gushing water problem, effectively control the scale and harm of the gushing water in the abandoned mine, and provide a good foundation for subsequent mine restoration work, which is environmentally friendly and sustainable.

[0037] In this embodiment, the gushing water can be treated on-site inside the abandoned mine shaft 1, and the corresponding amount of treatment reagent (organic layer 2 + limestone 3) is added into the shaft 1 through the dosing device according to the gushing water flow rate. After the pH of the gushing water after the treatment is detected to meet the first-level discharge standard of the "Comprehensive Sewage Discharge Standard" (GB 8978-1996), it is pumped out and discharged into the surrounding streams, thereby reducing the pollution to the surrounding environment and ensuring the stability and sustainability of the gushing water treatment. In addition, the method can also adapt to different gushing water scales and water quality characteristics, and has high adaptability and flexibility.

[0038] In some embodiments of the present application, the plurality of dosing devices include a first dosing device 5 and a second dosing device 6 connected in sequence, the first dosing device 5 is connected to the second dosing device 6 through the dosing pipe, and the second dosing device 6 extends into the vertical shaft 1 through the dosing pipe.

[0039] In some embodiments of the present application, the medication unit further includes a first medication dosing valve and a second medication dosing valve, the first medication dosing valve is connected to the medication dosing pipeline between the first medication dosing device 5 and the second medication dosing device 6, and the second medication dosing valve is connected to the medication dosing pipeline between the second medication dosing device 6 and the vertical shaft 1.

[0040] In some embodiments of the present application, the dosing unit further comprises an air-permeable package, wherein the air-permeable package wraps the limestone 3 and the organic layer 2, and the limestone 3 and the organic layer 2 are mixed in layers.

[0041] In this embodiment, the dosing treatment includes: using the shaft 1 as a reaction tank, and dosing on-site to treat the polluted water. By referring to the Slurry Acid Phytostabilization System (SAPS) process, the organic layer 2 and the limestone 3 filler are modularized and put into use, and the passive treatment technology SAPS technology is used to treat the acid mine drainage (AMD) to obtain a good treatment effect.

[0042] SAPS is an innovative ecological engineering technology that combines physical, chemical and biological processes to treat acid mine drainage. This technology combines an organic matter layer2 with a limestone3 filler to create a modular treatment system for neutralizing and stabilizing acidic materials in AMD.

[0043] In this embodiment, the organic layer 2 and the limestone 3 filler are mixed in layers and packaged in permeable ton bags so that the reagents can be replaced regularly. In this process, the sulfate-reducing bacteria (SRB) in the organic layer 2 use low molecular weight organic matter as electron donors to reduce sulfate, generate alkaline substances from the wastewater, and form metal sulfide precipitation. In addition, the limestone 3 filler layer also plays a role in adsorbing part of the suspended matter, increasing the alkalinity of the wastewater again, and forming metal hydroxide precipitation. After such treatment, the pH value of the wastewater increases, and the concentrations of iron ions, copper ions and sulfate ions are greatly reduced, thereby achieving the goal of water purification.

[0045] In some embodiments of the present application, the drainage unit further includes a drainage stop valve 9 , and the drainage stop valve 9 is connected to the drainage pipe 8 .

[0046] In this embodiment, the drainage of the shaft 1 includes: using reinforced concrete to enclose and collect water around the shaft 1, opening holes in the water collection facilities to set up pipes, and draining the gushing water by gravity flow. According to the amount of gushing water and the drainage distance, a suitable drainage pipe 8 is designed and laid. The material of the pipe can be selected from materials with good corrosion resistance, such as high-density polyethylene (HDPE) pipes or steel pipes. At the same time, it is necessary to install water gushing monitoring equipment to monitor the amount of gushing water and water quality in real time. Regularly inspect and maintain the drainage equipment to ensure its normal operation, and deal with equipment failures or damage in a timely manner.

[0047] Water quality testing includes: testing the discharged spring water to ensure that the pH of the treated spring water meets the first-level discharge standard of the "Comprehensive Sewage Discharge Standard" (GB 8978-1996) before it is pumped out and discharged into the surrounding streams, and regular water quality monitoring of the discharged spring water to ensure the stability and sustainability of the water quality treatment effect.

At the same time, by controlling the opening and closing of the valve, precise control of the gas collection and introduction process can be achieved. Such a gas collection system 10 can effectively collect and reuse hydrogen sulfide gas, improve reaction efficiency and reduce resource waste.

[0051] In some embodiments of the present application, a grouting and sealing unit is further included, wherein the grouting and sealing unit includes a grouting machine filled with slurry, and the grouting machine is directed toward the water seepage point on the side wall of the shaft 1.

[0052] In this embodiment, if there is water leakage on the side wall of the shaft 1, grouting and sealing treatment is required: the shaft 1 is sealed by grouting technology to prevent water from penetrating from the surrounding of the shaft 1. During grouting, it is necessary to ensure that there is no debris in the slurry. The slurry entering the grouting machine must be filtered through a screen, and full-hole one-time grouting is adopted. This measure can block the seepage and dripping points, reduce the drainage points of groundwater in the cave, and concentrate the drainage as much as possible on the current main water gushing points.

[0053] Optionally, the organic layer 2 agent and the limestone 3 agent are modularly processed using permeable bulk bags to facilitate later replacement.
