Description

Technical Field

[0001] The invention relates to the technical field of mine shaft wall water sprinkling treatment, and in particular to a vertical shaft water sprinkling treatment mechanism and method. Background Art

[0002] Mines generally use vertical shafts for lifting. However, water will gush out of the shaft of the vertical shaft during operation. After the water gushes out from the water outlet, it flows down along the shaft wall, gradually accelerating. Some of the water splashes off the shaft wall, forming water dripping, which covers the entire shaft, causing great inconvenience to personnel, material lifting and operations in the shaft. The shaft water dripping prevention scheme known to the inventor mainly adopts grouting to reduce the amount of water gush in the shaft or external metal objects to intercept the shaft water. For grouting, since there will be multiple water outlets in the shaft and the water outlet method is unclear, it leads to large engineering workload and high cost during treatment, and the water level will rise and form new water outlets as time goes by after water blocking. As for the use of external metal objects to intercept water to solve the shaft water dripping method, although this method has the characteristics of small engineering workload and low cost, it also has the problems of severe rust and difficult maintenance. Therefore, it is urgent to design a shaft water dripping solution that is simple to maintain. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide a vertical shaft water sprinkling management mechanism and method to solve the problems existing in the above-mentioned prior art, which can solve the shaft water sprinkling problem and is simple to maintain.

[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] The inventors are aware of a technical solution to solve the problem of shaft water sprinkling by using external metal objects to intercept water. However, the external metal objects are seriously corroded and difficult to maintain. In order to solve this problem, the present invention provides a shaft water sprinkling management mechanism, referring to Figure 1 and Figure 2 As shown, the present invention does not require external metal objects, and a circle of water intercepting grooves 3 are directly cut on the shaft wall 101. The water intercepting grooves 3 are located above the horse head gate 2 and below the concentrated water outlet point of the shaft wall 101. The horse head gate 2 is a transition section connecting the shaft bottom parking lot tunnel and the vertical shaft 1. At the connection between the vertical shaft 1 and the horizontal tunnel (stone gate), the space is relatively large, the top is inclined, and the cross-section is shaped like a horse head. It belongs to a known structure. A plurality of intercepting grooves 3 can be cut corresponding to water outlet points at different heights, and a corresponding intercepting groove 3 is arranged under each water outlet point, so as to achieve better water interception and drainage effect; an extension portion arranged obliquely upward is arranged at the bottom of the intercepting groove 3 and at one end close to the axis of the vertical shaft 1, and the water falling from the water outlet point is drained into the intercepting groove 3 by means of the extension portion; a water diversion hose 5 is fixedly arranged on the inner side wall of the vertical shaft 1, and its top is connected with the corresponding intercepting groove 3. When a plurality of intercepting grooves 3 are arranged from top to bottom, the upper intercepting groove 3 can be connected with the lower intercepting groove 3 through a water intercepting hose, and they are arranged in sequence, and the bottom of the lowest intercepting groove 3 is connected to the ditch of the horse head gate 2 through a water intercepting hose to achieve water interception and drainage.

[0031] In order to achieve a better drainage effect, the extended part of this embodiment adopts a smooth cofferdam 4 with a height of 10 cm. The cofferdam 4 is made of cement-water glass double liquid slurry and built along the inner circle of the trough bottom. The cofferdam 4 can intercept the water flowing out of the upper water outlet into the intercepting trough 3.

[0032] In order to allow the intercepting trough 3 to hold more water, the intercepting trough 3 is designed as a slope structure, which is gradually inclined downward from one end close to the center of the vertical shaft 1 to the end away from the center of the vertical shaft 1, that is, the intercepting trough 3 is cut obliquely downward. In a specific embodiment, the top wall and the bottom wall of the intercepting trough 3 are both at an angle of 45o with the horizontal direction, so that the intercepting trough 3 can hold more water.

[0033] In order to allow all the water in the intercepting trough 3 to enter the water diversion hose 5 and flow out to the ditch of the horse head gate 2, the height of the intercepting trough 3 close to the horse head gate 2 is designed to be 0.5m lower than the height opposite to the horse head gate 2, that is, the annular structure of the intercepting trough 3 is also arranged obliquely, such as Figure 2 As shown, the arrow indicates the direction of water flow; the water diversion hose 5 is connected to the lower end of the water intercepting groove 3, so that the water in the water intercepting groove 3 can enter the water diversion hose 5. In this embodiment, the water diversion hose 5 is connected to the inner wall of the vertical shaft 1 by a plurality of fixing clips spaced 6m apart in sequence.

[0034] The present invention also provides a method for treating water in a vertical shaft 1, comprising the following steps:

[0035] A circle of water intercepting groove 3 is cut on the wall 101 of the vertical shaft 1 above the horse head gate 2 and below the concentrated water outlet point of the wall 101 by using a notching machine; a cofferdam 4 is built along the outer circle of the bottom of the water intercepting groove 3 by using cement-water glass double liquid slurry, so that the water intercepting groove 3 is embedded in the wall 101, and the gushing water is connected to the water intercepting groove 3 by using the cofferdam 4; a water diversion hose 5 is externally connected to the bottom of the water intercepting groove 3 to lead the water in the water intercepting groove 3 to the next water intercepting groove 3 below or the ditch of the horse head gate 2.

[0036] Embodiment 1

[0037] The measured water inflow of each shaft of a certain iron mine is: 28.2m in the air intake shaft 3 / h, west return air shaft 13.7m 3 / h, auxiliary shaft 9.6m 3 / h, main shaft 14m 3 / h. In the early stage, the air intake shaft and the west return air shaft used external metal objects to block water. Waste belts and color steel tiles were used to install two water intercepting grooves 3 at 2m and 10m above the horse head gate 2. Water pipes were used under the water intercepting grooves 3 to intercept the water in the wellbore and lead it to the temporary water tank, which can intercept most of the water on the well wall 101. However, the following problems occurred during the construction process: first, the color steel tile water intercepting groove 3 was severely corroded and quickly lost its water interception effect; second, the belt water intercepting groove 3 was gradually filled with bucket spilled materials, and the water storage capacity decreased; third, the belt became loose due to the impact of the spilled materials, and could not fit with the well wall 101, resulting in water leakage; fourth, the water intercepting groove 3 was located above the horse head gate 2, which was difficult to maintain, which ultimately led to a significant reduction in the water interception effect and was basically abandoned.

[0038] In order to solve the above problems, this embodiment cuts a circular water intercepting groove 3 on the side wall of the auxiliary shaft of the iron ore mine. The water intercepting groove 3 is 30 cm high and 15 cm deep. A total of five water intercepting grooves 3 are set at the positions of -1040m, -930m, -828m, -545m, and -225m from the ground in the auxiliary shaft. When cutting, the water intercepting groove 3 is arranged along the circumference of the shaft wall 101 with a slope. The side of the horse head gate 2 of the water intercepting groove 3 is 0.5m lower than the opposite side of the horse head gate 2. A water diversion hose 5 made of flame-retardant material is embedded at the lowest point of the water intercepting groove 3. Then, a 10 cm high cofferdam 4 is built along the inner circle of the groove bottom using cement-water glass double liquid slurry, so that the water intercepting groove 3 is embedded in the shaft wall 101. The cofferdam 4 is used to connect the gushing water to the water intercepting groove 3 reserved in the shaft wall 101, and the water diversion hose 5 is used to connect the five water intercepting grooves 3 in sequence. The measured water interception volume exceeds 7m 3 / h, the water interception efficiency reaches 80%; there is almost no water in the auxiliary shaft, and personnel no longer need to wear raincoats when riding in buckets, and the working environment in the shaft is greatly improved; the embedded water interception trough 3 hardly occupies the internal space of the shaft, which is convenient for the construction of shaft equipment; the water interception trough 3 is located in the shaft wall 101, and it is not easy to accumulate spilled materials. And the material is concrete, which has good durability and almost no maintenance is required in the later stage.

[0039] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
