Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stratum treatment, and in particular to a horizontal flow to shallow layer grouting plugging treatment method under dynamic water conditions. BACKGROUND

[0002] Traditional coal mining technology will disturb the quaternary aquifer and cause a series of environmental and production problems. In terms of ecology, the water in the aquifer infiltrates through the water-conducting fissure zone, causing the shallow groundwater level to drop, damaging the regional water cycle system, weakening the water conservation capacity of the aquifer, and possibly causing degradation of surface vegetation, shrinkage of wetlands, and even affecting the water for daily use and agricultural irrigation of surrounding residents. In terms of mining safety, a large amount of water flowing into the underground mine will increase the water inflow of the mine, increase the drainage cost, and also possibly induce water inrush accidents, threatening the safety of miners; at the same time, the interaction between water and coal rock may soften the surrounding rock, reduce the stability of the coal seam roof, and exacerbate the deformation of the roadway, affecting the mining efficiency and resource recovery rate. In addition, long-term drainage may cause the aquifer to dry out, further exacerbating the shortage of regional water resources, forming a vicious cycle of ecology-production. Therefore, the present application proposes a horizontal flow to shallow layer grouting plugging treatment method under dynamic water conditions, which is constructed by interval distribution of short-distance directional horizontal holes and long-distance directional horizontal holes to build a closed curtain, and performs horizontal flow to shallow layer plugging treatment under dynamic water conditions, in order to protect the quaternary ecological aquifer and balance resource development and ecological protection.

[0024] As Figure 1 shown, the present application provides a horizontal flow to shallow grouting plugging treatment method under dynamic water conditions, comprising:

[0025] Step S1, constructing a vertical curtain in a predetermined treatment area to form a stable water layer in the treatment area.

[0026] In this embodiment, by constructing a vertical curtain, external layer flow supply can be cut off, and dynamic water environment can be isolated by dam body bottoming, so that a stable water layer is formed in the treatment area, avoiding the displacement of grout to outside the treatment area under dynamic water conditions, and facilitating subsequent construction operation.

[0027] Among them, the treatment area is selected according to the interlayer relationship between the strata and the quaternary water-rich condition, by finding the section which is easily affected by the coal mine roadway excavation and needs to be treated, a curtain is constructed in the treatment area to form a water-resisting layer, so as to prevent water resources loss of the quaternary ecological water-bearing layer.

[0028] Step S2, constructing a filling curtain in the treatment area to connect the filling curtain with the vertical curtain to form a water-resisting layer.

[0029] Among them, by constructing a filling curtain in the treatment area and connecting the filling curtain with the vertical curtain to form a water-resisting layer, water resources loss of the upper water-bearing layer caused by the water-conducting fractured zone generated in the process of coal mining is prevented, adverse effects on the ecological environment are avoided, the quaternary ecological water-bearing layer is protected, and the role of protecting the ecological environment and the domestic water of nearby residents is played.

[0030] In some embodiments, step S1 specifically comprises:

[0031] Step S11, calculating a first drilling position according to the treatment area.

[0032] In this embodiment, asFigure 5 As shown, the first drilling position is the first sequence hole shown in the figure, which is set at the outermost side of the treatment area. The spacing and number of the first drilling positions can be reasonably adjusted according to the actual geological conditions.

[0033] Step S12: opening a first borehole according to the first borehole position.

[0034] Step S13: grouting is performed into the first borehole to obtain a vertical curtain.

[0035] Among them, such as Figure 2 As shown, by opening a first borehole at the first borehole location and grouting the first borehole, external laminar recharge is cut off, forming a stable water layer within the treatment area. During the construction of the first borehole, short-distance branch holes can be constructed by overlapping the casing of the long-distance horizontal hole, with the drilling trajectory parallel to the long branch directional horizontal hole.

[0036] In some embodiments, the filling curtain includes a curtain frame and a reinforcing curtain.

[0037] Step S2 specifically includes:

[0038] Step S21: constructing a curtain frame in the treatment area, wherein the curtain frame is arranged perpendicular to the vertical curtain.

[0039] Step S22: constructing a reinforced curtain in the gap between at least two curtain frames, wherein the reinforced curtain is arranged parallel to the curtain frames.

[0040] In this embodiment, the curtain frame is used to fill the treatment area to form a water-proof layer, and the reinforcing curtain is used to strengthen the gaps between the curtain frames and reinforce the water-proof layer.

[0041] In some embodiments, step S21 specifically includes:

[0042] Step S211 : calculating a second drilling position according to the position of the vertical curtain.

[0043] In this embodiment, if Figure 5 As shown, the second drilling position is the second-order hole shown in the figure, which is set in the middle of the treatment area. The spacing and number of the second drilling positions can be reasonably adjusted according to the actual geological conditions.

[0044] Step S212: Drill a second hole according to the second hole location, wherein the second hole is drilled using a long distance.

[0045] Step S213: Grouting the second borehole using a forward grouting method to obtain a curtain frame, wherein the grouting distance of the forward grouting method is 25 to 100 meters.

[0046] Among them, such as Figure 3 As shown, a long-distance horizontal curtain is formed in the long-distance borehole by opening a long-distance borehole at a second borehole position and grouting the second borehole.

[0047] Preferably, in order to improve the strength of the curtain frame, the grouting distance of the forward grouting method is preferably 50m.

[0048] In some embodiments, step S22 specifically includes:

[0049] Step S221 : calculating the third drilling position according to the position of the curtain frame.

[0050] In this embodiment, if Figure 5 As shown, the third drilling position is the three-sequence hole shown in the figure, which is set between the curtain frame and the vertical curtain. The spacing and number of the third drilling positions can be reasonably adjusted according to actual geological conditions.

[0051] Step S222: Drill a third borehole according to the third borehole position, wherein the third borehole is drilled in a short distance.

[0052] Step S223: Grouting is performed on the third borehole to obtain a reinforced curtain.

[0053] Among them, such as Figure 4 As shown, the waterproof layer is reinforced by opening a long-distance borehole at the third borehole position and grouting the third borehole.

[0054] Preferably, the third borehole treatment layer is mainly the top of the weathered bedrock, and short-distance directional horizontal hole grouting is carried out between the second boreholes, arranged parallel to the second boreholes, to fill the horizontal waterproof curtain and strengthen the curtain filling in the curtain skeleton established by the long-distance horizontal grouting holes, and short-distance directional horizontal hole grouting is added at the connection of the long-distance horizontal grouting holes to further strengthen the curtain filling, so that the overall waterproof effect of the waterproof curtain is stronger.

[0055] As an optional implementation method, the construction of grouting holes follows the principle of "sparse first, dense later, and construction in sequence": first construct the grouting holes on all sides, overlap with the bottom of the Quaternary system and isolate the dynamic water environment; then construct the long horizontal holes to build the curtain skeleton; finally, construct the remaining short horizontal holes and fill the horizontal water-blocking curtain.

[0056] As an optional implementation, the method provided by the application can also form a vertical grouting curtain by first using long-distance horizontal holes to drain and grout at the edge of the selected treatment area, cut off the external laminar flow supply, connect to the bottom of the dam body, and isolate the dynamic water environment, so as to form a stable water layer in the treatment area; form a horizontal curtain by using long-distance horizontal holes to drain and grout in the water conducting fractured zone supply area in the treatment area, and build a curtain skeleton; arrange short-distance directional horizontal holes between the long-distance directional horizontal hole skeletons, so that the short-distance directional horizontal holes are distributed at intervals with the long-distance directional horizontal holes, and increase short-distance horizontal holes at the connection between the long-distance holes, so as to achieve the effect of strengthening the curtain filling.

[0057] As an optional implementation, the method provided by the application builds a closed vertical curtain when the upper aquifer is in a horizontal dynamic water condition, cuts off the external laminar flow supply, and prevents the slurry from being washed out of the treatment area under dynamic water conditions. Further, shallow plugging treatment is performed by long-distance horizontal hole grouting and short-distance horizontal hole grouting to prevent the water resources of the upper aquifer from being lost due to the water conducting fractured zone caused by coal mining, thereby causing adverse effects on the ecological environment, and further playing a role in protecting the fourth ecological aquifer and the ecological environment and the domestic water of nearby residents. The long-distance directional horizontal hole is filled to form a horizontal curtain, thereby forming a stable aquifuge.

[0058] As an optional implementation, as shown in Figure 5 The first borehole (first sequence hole) includes short-distance boreholes for grouting on both sides and long-distance boreholes for grouting on one side, the long-distance boreholes are used to fill the treatment area, and the short-distance boreholes are used to reinforce the vertical curtain, so as to build a vertical curtain with high strength.

[0059] As an optional implementation, as shown in Figure 5 The second borehole (second sequence hole) includes short-distance boreholes for grouting on both sides and long-distance boreholes for grouting on one side, the long-distance boreholes are used to fill the treatment area, and the short-distance boreholes are used to reinforce the vertical curtain, so as to build a vertical curtain with high strength.

[0060] As an optional implementation, as shown in Figure 5 The third borehole (third sequence hole) only includes short-distance boreholes for grouting on both sides, the third borehole is used to further reinforce the treatment area, so as to make the aquifuge have a more stable structure and prevent the fourth ecological aquifer from losing water resources.

[0061] As an optional implementation, under the horizontal water environment, the grouting slurry in the first sequence hole has a relatively short diffusion distance, but has a higher requirement for the setting speed, and needs to quickly isolate the water environment, so the grouting material is single liquid cement slurry. However, the single liquid cement slurry has a relatively high cost and a relatively short diffusion distance, and is not suitable for wide use in the second sequence and the third sequence. Therefore, clay cement slurry is used in the second sequence and the third sequence, more than 90% of which is natural clay in volume ratio. The diffusion distance is relatively far, and the cost is relatively low. The grouting density of the clay cement slurry in the second sequence and the third sequence is strengthened. Through different grouting materials and different processes, the dual protection of engineering quality and economy is realized.

[0062] As can be seen from the above embodiments of the application, the vertical curtain is constructed in the treatment area to form a stable water layer in the treatment area, facilitating subsequent construction. The filling curtain is constructed in the treatment area, and the filling curtain is connected with the vertical curtain to form a water-resisting layer, thereby protecting the fourth system ecological water-bearing layer, preventing regional water resource shortage, balancing resource development and ecological protection, and forming an ecological-production virtuous cycle.

[0063] It should be noted that the method of the embodiments of the application can be executed by a single device, such as a computer or a server. The method of the embodiments can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In this distributed scenario, one of the multiple devices can only execute one or more steps in the method of the embodiments of the application, and the multiple devices can interact with each other to complete the method.
