Description

Technical Field

[0001] This invention belongs to the field of underground mine drainage technology, and relates to a water distribution tunnel structure for an underground mine drainage pumping station. Background Technology

[0002] The underground drainage system is a crucial facility for ensuring safe mining operations. Drainage is a continuous process that cannot be interrupted for extended periods. The main drainage pump house is responsible for all underground drainage work in the mine. Underground water and production wastewater are collected in the pump house's water tank through drainage boreholes, drainage wells, and ditches. From there, the water is distributed to various pumps via distribution tunnels to discharge underground water, production wastewater, and backfill water. This water often contains varying levels of silt and sand. After prolonged drainage, a certain amount of silt and sand will settle in the water tank and distribution tunnels, requiring timely cleaning to maintain adequate water storage capacity. The water tank consists of two independent main and auxiliary tanks. These tanks can be used simultaneously or separately, allowing both tanks to operate concurrently, or one tank to be cleaned while the other is in operation.

[0003] However, current mine pump houses often only have one water distribution tunnel, making simultaneous operation of pumping and cleaning impossible. Excessive sediment buildup in the distribution tunnel can shorten the lifespan of the pumps and severely impact their normal operation. Cleaning the sediment requires shutting down the pumps and utilizing the effective volume of the water tank, but this necessitates manual cleaning by workers entering the tunnel, which is time-consuming, and the water tank's capacity is often insufficient. Furthermore, significant sediment buildup in the distribution tunnel reduces its effective flow area. Therefore, mines often allocate a certain amount of unused area within the distribution tunnel for sediment deposition, resulting in larger cross-sections and increased engineering work and infrastructure investment. Summary of the Invention

[0004] In order to overcome the defects in the existing technology, the present invention provides a water distribution tunnel structure for a mine underground drainage pumping station, which can ensure that the operation of the mine underground drainage system is not affected during the cleaning of any water tank under normal water inflow conditions. It has strong working capacity, is easy to clean, reduces the labor intensity of workers, and reduces the amount of engineering work.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a water distribution tunnel structure for a mine underground drainage pumping station, wherein the first water distribution well and the second water distribution well, which are independently set up, are each connected to a water tank and a water distribution tunnel, and a common intermediate water distribution tunnel is also connected between the first water distribution well and the second water distribution well; each of the above water distribution tunnels is connected to a water intake well, and at least one water distribution gate valve is provided at the connection between the first water distribution well, the second water distribution well and the water tank and the intermediate water distribution tunnel.

[0006] As a further embodiment of the present invention, the bottom elevation of the first water distribution well, the second water distribution well, and each water intake well is lower than the bottom elevation of each water tank and each water distribution tunnel.

[0007] As a further embodiment of the present invention, each water distribution lane slopes toward the water intake well connected to it.

[0008] As a further embodiment of the present invention, the suction well connected to the intermediate water distribution lane is located in the middle of the intermediate water distribution lane on the side away from the water tank, and the other suction wells are located at the ends of their respective water distribution lanes on the side away from the water tank.

[0009] As a further embodiment of the present invention, each water distribution gate valve is an electric water distribution gate valve.

[0010] As a further embodiment of the present invention, at least the inlet side of the water distribution gate valve at the connection between the first water distribution well, the second water distribution well and their respective water tanks is provided with a filter screen.

[0011] As a further embodiment of the present invention, the first water distribution well, the second water distribution well, and each water intake well are respectively equipped with water pump suction pipes.

[0012] Compared with the prior art, the beneficial effects of the present invention include:

[0013] (1) By setting a water distribution tunnel on both sides of the first water distribution well and the second water distribution well and between them, the present invention can ensure that the operation of the underground drainage system of the mine is not affected when any water tank is cleaned, and has strong working capacity.

[0014] (2) The bottom elevation of the water distribution well in this invention is lower than that of the water tank, forming a primary sedimentation of mud and sand into the water distribution well. Each water distribution lane slopes toward the water intake well connected to it, forming a secondary sedimentation of mud and sand into the water intake well. The sedimented mud and sand are collected by the water pool at the bottom of the water distribution well and the water intake well. There is no need to clean the water distribution lane. It is only necessary to clean the mud and sand in the water pool at the bottom of the water distribution well and the water intake well periodically.

[0015] (3) The cleaning area is divided reasonably. The first water distribution well and the suction well on one side of it are cleaned at the same time, the second water distribution well and the suction well on one side of it are cleaned at the same time, and the public suction well is cleaned separately, so as not to affect the normal operation of the mine underground drainage system under normal water inflow.

[0016] (4) There is no sediment deposition in the water distribution tunnel, which can effectively increase the water flow area of ​​the water distribution tunnel and reduce the cross-sectional size and engineering volume of the water distribution tunnel;

[0017] (5) It has a simple structure and strong applicability, and can be used in suction drainage pump rooms with 4 to 10 water pumps. Attached Figure Description

Furthermore, the terms "first," "second," "third," and "fourth" are only used to distinguish components and should not be construed as indicating or implying relative importance.

[0026] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Example 1

[0028] like Figure 1As shown, the water distribution tunnel structure of the mine underground drainage pumping station in this embodiment can ensure that the operation of the mine underground drainage system is not affected when any water tank is being cleaned. It includes a first water distribution well 1, a second water distribution well 2, a middle water distribution tunnel 3, a left wing water distribution tunnel 4, a right wing water distribution tunnel 5, a right wing suction well 50, a middle suction well 30, a left wing suction well 40, and a right wing suction well 50.

[0029] The first water distribution well 1 is connected to the first water tank 10 via the first water distribution gate valve 11. The second water distribution well 2 is connected to the second water tank 20 via the second water distribution gate valve 21. The two ends of the intermediate water distribution tunnel 3 are connected to the first water distribution well 1 and the second water distribution well 2 via the third water distribution gate valve 31 and the fourth water distribution gate valve 32, respectively. The left wing water distribution tunnel 4 is connected to the first water distribution well 1, and the right wing water distribution tunnel 5 is connected to the second water distribution well 2. In this embodiment, the left wing water distribution tunnel 4 is directly connected to the first water distribution well 1, and the right wing water distribution tunnel 5 is directly connected to the second water distribution well 2. Well 2 is directly connected; however, depending on the actual use and the need for opening and closing, a water distribution gate valve may be installed between the left wing water distribution lane 4 and the first water distribution well 1 or between the right wing water distribution lane 5 and the second water distribution well 2. The middle suction well 30 is located in the middle of the middle water distribution lane 3 on the side away from the water tank and is connected to the middle water distribution lane 3. The left wing suction well 40 is located at the end of the left wing water distribution lane 4 on the side away from the water tank and is connected to the left wing water distribution lane 4. The right wing suction well 50 is located at the end of the right wing water distribution lane 5 on the side away from the water tank and is connected to the right wing water distribution lane 5.

[0030] To allow silt to settle at the bottom of the distribution and intake wells, thus eliminating the need for cleaning the entire distribution tunnel, the bottom elevations of the first distribution well (1), the second distribution well (2), and each intake well are lower than the bottom elevations of the water tanks and distribution tunnels. This creates primary sedimentation of silt towards the distribution wells. Each distribution tunnel slopes towards its connected intake well, creating secondary sedimentation of silt towards the intake well. Specifically:

[0031] The bottom elevations of the first water distribution well 1 and the second water distribution well 2 are the same, and 1m to 2m lower than the bottom elevations of the first water tank 10 and the second water tank 20. The bottom elevations of the intermediate water distribution tunnel 3, the left wing water distribution tunnel 4, and the right wing water distribution tunnel 5 are the same as the bottom elevations of the first water tank 10 and the second water tank 20. The bottom elevations of the intermediate water intake well 30, the left wing water intake well 40, and the right wing water intake well 50 are the same as the bottom elevations of the first water distribution well 1 and the second water distribution well 2. The bottom of the intermediate water distribution tunnel 3 slopes towards the intermediate water intake well 30, the bottom of the left wing water distribution tunnel 4 slopes towards the left wing water intake well 40, and the bottom of the right wing water distribution tunnel 5 slopes towards the right wing water intake well 50. Preferably, the slopes are all 3‰ to 5‰.

[0032] Preferably, there are one to two first water distribution gate valves 11, second water distribution gate valves 21, third water distribution gate valves 31 and fourth water distribution gate valves 32, and all of them are electric water distribution gate valves. The inlet side of the first water distribution gate valve 11 and the second water distribution gate valve 21 are provided with a filter screen.

[0033] The suction pipes for one or two water pumps can be installed in the first water distribution well 1, the second water distribution well 2, the middle water intake well 30, the left wing water intake well 40, and the right wing water intake well 50.

[0034] Based on the above water distribution tunnel structure, its working process is as follows: the left wing suction well 40 and the first water distribution well 1 are cleaned at the same time. At this time, the first water distribution gate valve 11 and the third water distribution gate valve 31 are closed. The middle suction well 30, the right wing suction well 50 and the second water distribution well 2 work at the same time, and the working capacity is strong.

[0035] The middle suction well 30 is cleaned separately. At this time, the third water distribution gate valve 31 and the fourth water distribution gate valve 32 are closed. The left wing suction well 40, the right wing suction well 50, the first water distribution well 1, and the second water distribution well 2 work simultaneously, which has a strong working capacity.

[0036] The right wing intake well 50 and the second distribution well 2 are cleaned at the same time. At this time, the second distribution gate valve 21 and the fourth distribution gate valve 32 are closed. The left wing intake well 40, the first distribution well 1 and the middle intake well 30 work at the same time, which has a strong working capacity.

[0037] When cleaning the first water tank 10, only the first water distribution gate valve 11 needs to be shut off, and the rest of the equipment will continue to operate normally. Similarly, when cleaning the second water tank 20, only the second water distribution gate valve 21 needs to be shut off, and the rest of the equipment will continue to operate normally.

[0038] The water distribution tunnel structure of the mine underground drainage pumping station described in this embodiment of the invention is simple in structure and highly applicable. Under normal water inflow conditions underground, the cleaning of the water tank and the water distribution tunnel can be carried out separately, and the cleaning does not affect the operation of the mine underground drainage system. This facilitates cleaning, reduces the labor intensity of workers, and reduces the amount of engineering work.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
