Description

Technical Field

[0001] This application relates to drilling plugging technology, and is a rapid hole-sealing device for fracture-induced drilling in mines and its application. Background Art

[0002] Fracture-induced Drilling is a technology that guides the directional fracture of rock masses or coal seams through pre-set drilling, and is widely used in mine exploitation, geothermal energy development, oil and gas production enhancement, and tunnel engineering. Its core lies in forming controllable fractures in the target horizon through physical or chemical means to improve resource extraction efficiency or engineering safety.

[0003] To prevent groundwater leakage, harmful gas escape, or formation instability, fracture-induced drilling needs to be plugged. The plugging in the prior art is to seal the constructed fracture-induced drilling through physical or chemical means, and is widely used in fields such as mine closure, oil and gas well abandonment, and post-treatment of geothermal energy development.

[0004] In the prior art, the plugging materials mainly include nano-composite slurries (silicate + carbon nanotubes + graphene oxide), bio-mineralization binders (bacterial-induced calcium carbonate precipitation by Bacillus pasteurii), etc. These plugging materials are directly poured into the fracture-induced drilling using grouting or injection devices, and expand upon contact with water to form a plug. The plugging materials also include 4D printing intelligent plugging bodies (shape memory polymers (SMP)), and these plugging materials automatically adjust the topological structure of the plugging body according to the deformation of the drilling hole.

[0005] However, at some sites, in addition to the above plugging materials, temporary plugging is sometimes carried out. It uses materials such as crushed stones and fine sand for filling, and then uses a pressing device to tamp. This method requires different devices such as a discharging device and a pressing device to operate separately, and the plugging efficiency is low.

[0006] Therefore, it is necessary to design a rapid hole-sealing device for fracture-induced drilling in mines that can improve the efficiency of temporary plugging. Summary of the Invention

[0007] This application provides a rapid hole-sealing device for fracture-induced drilling in mines and its application, which solves the problems in the above prior art: multiple tools are required for cooperation in temporary plugging, and the plugging efficiency is low; and achieves the technical effect of quickly tamping the plugging material in the hopper into the drilling hole under the dual action of a vibration device and a tamping device that reciprocates up and down, thereby improving the efficiency of temporary plugging.

[0012] Tracks are arranged on the upper surface of the platform. The base of the hopper is slidably connected to the tracks in a matching manner.

[0013] The platform discharge opening is provided on the bottom surface of the track. The aforementioned hopper discharge opening is located above the track.

[0014] The second connecting member includes a first hoop fixedly connected to the vibrating rod, and a second hoop fixedly connected to the first hoop. The first hoop is fixedly connected to the horizontally arranged vibrating rod. The second hoop is sleeved on the ramming rod.

[0015] A support rod is arranged between the suspension rod and the vibrating rod. One end of the support rod is fixedly connected to the main rod. A first connecting member is fixed on the support rod. The first connecting member includes a first sleeve fixedly connected to the support rod. A second sleeve is fixedly connected to the outside of the side wall of the first sleeve. The two ends of the second sleeve are open and arranged vertically. The second sleeve is sleeved on the ramming rod.

[0016] A traction device is fixed on the main rod. The traction device includes a wire - winding wheel. A pulley is hung on the suspension rod. The upper end of the ramming rod is fixedly connected to a traction rope. The other end of the traction rope is connected to the wire - winding wheel of the traction device after passing through the pulley.

[0017] The application of a rapid hole - sealing device for mine fracture drilling includes the following steps: Step 1: Move the platform above the drilling hole so that the platform discharge opening is directly above the drilling hole; Step 2: Install multiple hoppers in place on the inlet side of the track, and then fill the hoppers with plugging materials; Step 3: Loosen the second hoop of the second connecting piece, and lift the ramming rod through the traction device so that the space between the lower side of the vibrating head and the track allows the hopper to enter; Step 4: Push the foremost hopper under the ramming rod so that the hopper discharge port is aligned with the platform discharge port, and then pull out the plug board, and the plugging material starts to enter the drill hole; Step 5: After the plugging material enters the drill hole and forms a certain height, lower the ramming rod until the lower end of the vibrating head contacts the plugging material, stop the traction device and then lock the second hoop, and then start the vibrating device to compact the plugging material; Step 6: After vibrating for a certain period of time, stop the vibrating device, loosen the second hoop, start the traction device to lift the ramming rod until the ramming rod is higher than the hopper discharge port, and the plugging material enters the drill hole again.

Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0028] The following further describes this application in combination with embodiments and the accompanying drawings. Embodiment: As shown in the attached Figures 1-4 figure, a rapid hole - sealing device for mine fracturing drilling includes a movable platform 6. A movable hopper 9 is arranged on the upper surface of the platform 6. Corresponding hopper discharge openings 9 - 2 and platform discharge openings 16 are provided on the bottom surface of the hopper 9 and the platform 6. A main rod 4 is arranged on one side of the platform 6. A suspension rod 1 is fixedly arranged on the upper side of the main rod 4. A vibrating rod 11 is hinged to the lower part of the main rod 4. A liftable ramming rod 5 is hung at the suspension rod 1. A vibrating device 12 capable of driving the vibrating rod 11 to swing up and down is installed on the vibrating rod 11. The ramming rod 5 is connected to the vibrating rod 11 through a second connecting member 8.

[0029] As Figure 3 shown in the figure, a ramming head 10 is installed at the lower end of the ramming rod 5. The ramming head 10 includes a cavity outer cylinder 10 - 1 fixedly connected to the ramming rod 5. The lower end of the outer cylinder 10 - 1 is open. A liftable vibrating head 10 - 3 is arranged inside the outer cylinder 10 - 1. The upper end surface of the vibrating head 10 - 3 and the upper end surface of the outer cylinder 10 - 1 are connected through an elastic member, and the elastic member can be a spring 10 - 2.

[0030] Further, the lower part of the ramming rod 5 extends into the outer cylinder 10 - 1. The vibrating head 10 - 3 is provided with an insertion opening for the ramming rod 5 to insert. The vibrating head 10 - 3 is sleeved on the lower end of the ramming rod 5. The spring 10 - 2 is sleeved on the ramming rod 5 between the vibrating head 10 - 3 and the upper end surface of the outer cylinder 10 - 1.

[0031] When the ramming rod 5 trembles up and down, the vibrating head 10 - 3 is restricted in its lateral displacement by the outer cylinder 10 - 1 and the ramming rod 5, and can only tremble up and down along the outer cylinder 10 - 1, thereby compacting the sealing material.

[0032] As Figure 4As shown in the figure, the hopper 9 includes a base 9-3 and a cavity cylinder 9-1 with an open upper end fixed on the base 9-3. A hopper discharge opening 9-2 penetrating the base 9-3 is provided at the center of the base 9-3. An insertion opening communicating with the hopper discharge opening 9-2 is provided on the side wall of the base 9-3, and a plug plate 9-4 is inserted into the insertion opening. After the plug plate 9-4 is inserted inward into the insertion opening, the hopper discharge opening 9-2 can be cut off, so that the plugging material in the hopper 9 cannot fall. Pulling out the plug plate 9-4 outward can open the hopper discharge opening 9-2, so that the plugging material in the hopper 9 can enter the platform discharge opening 16 along the hopper discharge opening 9-2 and finally enter the drill hole 15.

[0033] Furthermore, a track 7 is provided on the upper surface of the platform 6. The base 9-3 of the hopper 9 is slidably connected to the track in a matching manner, so that the hopper 9 can move along the track 7. The inlet of the track 7 is provided on one side of the platform 6, and the outlet of the track 7 is provided on the other side of the platform 6. Thus, when multiple hoppers 9 are on the track 7, the hopper 9 that has unloaded the plugging material can be removed from the outlet of the track, and the subsequent hopper 9 can move forward to the hopper discharge opening 9-2 for discharging and plugging.

[0034] The track 7 is a track groove. A pulley is installed on the bottom surface of the base 9-3 of the hopper 9, and the pulley slides in the track. The pulley is a universal wheel. The specific structure is not the inventive point of this application and will not be described in detail here.

[0035] The aforementioned platform discharge opening 16 is opened on the bottom surface of the track groove. The aforementioned hopper discharge opening 9-2 is located directly above the track groove. The hopper discharge opening 9-2 and the platform discharge opening 16 are on the same straight line and are directly below the ramming rod 5.

[0036] After the plugging material enters the drill hole 15 through the hopper discharge opening 9-2 and the platform discharge opening 16 and forms a stack, lower the ramming rod 5 so that the ramming head 10 enters the drill hole 15 through the hopper discharge opening 9-2 and the platform discharge opening 16. After starting the vibration device 12, the vibration rod 11 vibrates up and down, thereby driving the ramming rod 5 to vibrate up and down. As a result, the vibration head 10-3 suspended in the outer cylinder 10-1 by the spring 10-2 will also vibrate up and down, and then repeatedly hammer and press the stacked plugging material, so that the plugging material is gradually compacted. After the plugging material entering the drill hole is compacted, lift the ramming rod 5 to open the hopper discharge opening 9-2 and the platform discharge opening 16. The plugging material in the hopper 9 enters the drill hole 15 again, and repeat the above steps until the plugging material in the drill hole 15 is compacted to the upper port of the drill hole 15. Then, push the plug plate 9-4 inward to cut off the hopper discharge opening 9-2 to complete the plugging operation.

[0037] The vibration device 12 in this application is a prior art, which can form an up-and-down vibration effect. The specific structure is not the inventive point of this application and will not be described in detail here.

[0038] Further, the second connecting member 8 includes a first hoop fixedly connected to the vibrating rod 11, a second hoop fixedly connected to the first hoop. The first hoop is fixedly connected to the horizontally arranged vibrating rod 11, and the second hoop is sleeved on the ramming rod 5. When lifting and lowering the ramming rod 5, the second hoop can be loosened so that the ramming rod 5 is located within the second hoop but not fixedly connected. Before starting the vibration device 12, tighten the second hoop so that the ramming rod 5 is located within the second hoop and fixedly connected.

[0039] As Figure 1 、 2 shown, in order to keep the ramming rod 5 stable during the lifting and lowering process (non-vibrating) and prevent swaying, a support rod 13 is provided between the suspension rod 1 and the vibrating rod 11. One end of the support rod 13 is fixedly connected to the main rod 4. A first connecting member 14 is fixed on the support rod 13. The first connecting member includes a first sleeve fixedly connected to the support rod 13. A second sleeve is fixedly connected to the outer side wall of the first sleeve. The two ends of the second sleeve are open and arranged vertically. The second sleeve is sleeved outside the ramming rod 5. Through the first connecting member 14, the ramming rod 5 can only move up and down.

[0040] The lifting and lowering of the ramming rod 5 is controlled by a traction device 3. The traction device 3 is fixed on the main rod 4. The traction device 3 includes a wire winding wheel. A pulley 2 is suspended on the suspension rod 1. The upper end of the ramming rod 5 is fixedly connected to the traction rope. The other end of the traction rope is connected to the wire winding wheel of the traction device 3 after passing through the pulley 2. The traction device 3 can be a motor, and the wire winding wheel is installed on the power output shaft of the motor. By controlling the forward and reverse rotation of the motor, the traction rope can be wound and unwound, thereby realizing the lifting and lowering of the ramming rod 5.

[0041] In order to enable the platform 6 to move, walking wheels or crawlers are installed on the bottom surface of the platform 6, and the driving device drives the walking wheels or crawlers to rotate, thereby realizing the movement of the platform 6. The specific structure is not the invention point of this application and is already existing technology, so this application will not describe it in detail here.

[0042] The application of a rapid hole-sealing device for mine fracturing drilling includes the following steps: Step 1: Move the platform 6 above the drilling hole 15 so that the platform material discharge port 16 is directly above the drilling hole 15; Step 2: Install multiple hoppers 9 in place from the inlet side of the track 7, and then fill the hoppers 9 with plugging materials; Step 3: Loosen the second hoop of the second connecting member 8, and lift the ramming rod 5 through the traction device 3 so that the space between the lower side of the vibration head 10-3 and the track 7 allows the hopper 9 to enter; Step 4: Push the foremost hopper 9 below the ramming rod 5 so that the hopper material discharge port 9-2 is aligned with the platform material discharge port 16, and then pull out the plug board 9-4, and the plugging material starts to enter the drilling hole 15; Step 5: After the plugging material enters the borehole and reaches a certain height, lower the ramming rod 5 until the lower end of the vibrating head 10-3 contacts the plugging material. Then, stop the traction device 3 and lock the second hoop. Subsequently, start the vibration device 12 to compact the plugging material. Step 6: After vibrating for a certain period of time, stop the vibration device 12, loosen the second hoop, start the traction device 3 to lift the ramming rod 5 until the ramming rod 5 is higher than the hopper discharge port 9-2. The plugging material enters the borehole 15 again. Repeat Step 5 until the plugging material in the borehole 15 is compacted close to the upper port of the borehole 15. Step 7: Move the platform 6 away and pour cement mortar into the remaining part of the borehole 15 for port plugging.

[0043] Further, in Steps 4-6, if the plugging material in one hopper 9 is not enough to plug one borehole, after the plugging material in this hopper 9 is used up, push this hopper 9 towards the outlet side of the guide rail 7, and then push the subsequent hoppers 9 along the guide rail to below the ramming rod 5. Repeat Steps 4-6.

[0044] Further, the certain height in Step 5 means that generally the required borehole depth is about 2m, so this height can be set to 50-100cm. Of course, in actual operation, it is difficult to accurately determine the pouring height. It can be simply judged according to the feeding amount and the borehole diameter. Generally, after 2-4 pourings, it is sufficient that the plugging material is close to the upper port of the borehole 15 after compaction.

[0045] Further, the certain period of time in the step means that for temporary plugging materials such as crushed stones and sand, the vibration time can be 1-2 minutes. For plugging materials such as cement mortar, the vibration time can be 10-15 minutes.

[0046] If the plugging material in this application is changed to cement mortar, then the vibration of the vibrating head 10-3 plays a role in stirring the cement mortar, enabling the cement mortar entering the borehole to coagulate evenly. During the construction process, the ramming rod 5 can be intermittently lifted and lowered to vibrate and stir the plugging material at different heights. The specific implementation steps are the same as the above application steps.

[0047] The borehole 15 temporarily plugged by this application can reduce the risk of gas leakage by ≥90%, reduce the impact ground pressure accident rate by 70%, and the surface settlement rate after plugging is ≤0.1mm / day.

[0048] The above description is only an example for clearly explaining this application, and is not a limitation on the implementation mode of this application. Any obvious changes or variations derived from the technical solution of this application still fall within the protection scope of this application.
