Description

Technical Field

[0001] This utility model relates to the field of liquid explosive loading technology, and in particular to a liquid explosive pump loading structure with a water-containing hole. Background Technology

[0002] Deep-hole blasting in coal mines is an effective technical means to solve problems such as pre-fracture of hard coal and rock, prevention of rockburst, and permeability enhancement of low-permeability coal and rock. It utilizes the high explosive energy of explosives in large-diameter, high-charge boreholes to achieve volumetric fracturing of the surrounding rock. However, based on the current mainstream products of solid explosives in coal mines, the applicability of deep-hole blasting technology in coal mines is greatly limited.

[0003] As is well known, the stress and deformation of ultra-deep boreholes in coal mines, as well as the impact of cuttings and even borehole collapse, can affect the loading of solid explosives. This results in high labor intensity and low loading efficiency for deep-hole loading, and in some cases, it is even impossible to complete the loading process. This not only wastes drilling resources but also significantly reduces the fracturing effect of deep-hole blasting due to insufficient loading. To address this issue, a liquid explosive pump-injection loading process has been developed. Based on the fluidity of liquid explosives, this process enables pump-injection loading within the borehole, reducing the limitations imposed by borehole deformation on deep-hole loading.

[0004] During the above-mentioned liquid explosive pump filling process, the sensitivity of liquid explosives decreases when they come into contact with water, making detonation difficult. Water cannot be stored in the borehole. Therefore, a liquid explosive pump filling structure with a water-containing borehole is needed to help solve the above problems. Utility Model Content

[0005] In view of the technical problems in the prior art, liquid explosives become less sensitive and difficult to detonate when exposed to water, and water cannot be stored in the borehole, this utility model provides a liquid explosive pump filling structure in a water-containing borehole.

[0006] The technical solution adopted in this utility model is: a liquid explosive pump filling structure in a water-containing hole, comprising: A sealing section is located outside the water-bearing hole, and a charging section is formed between the inner wall of the water-bearing hole and the end of the sealing section; A waterproof strip is located inside the charging section. The waterproof strip is used to contain liquid explosives, isolate water in the water-bearing holes, and expand and squeeze out water from the water-bearing holes. The sealing section has three through holes, in which a drain pipe, an injection pipe, and a detonating cord are installed respectively. The end of the drain pipe is located outside the waterproof strip inside the charging section, while the ends of the injection pipe and the detonating cord are located inside the waterproof strip. The fastener is used to secure the inlet end of the waterproof tape to ensure a sealed interior.

[0007] Furthermore, the fastener is a rope, which can be used to tie the end of the waterproof tape tightly.

[0008] Furthermore, the fixing component includes a fixing block and an installation ring. The fixing block is fixedly installed on the sealing section. The installation ring is provided with an annular clip and has a slot. The annular clip corresponds to the slot and engages with the slot to fix the end of the waterproof tape in the slot.

[0009] Furthermore, the through hole containing the injection tube and detonating cord extends through to the surface of the fixing block.

[0010] Furthermore, the end of the annular clip is a protruding head, which allows the annular clip to be stably engaged with the slot.

[0011] Furthermore, the protruding head has an arc-shaped edge.

[0012] The beneficial effects of this utility model are: 1. By setting up a waterproof belt, the pump body and the injection pipe can draw liquid explosive into the waterproof belt. The waterproof belt gradually expands, thereby squeezing out the water in the water-bearing hole and draining it through the drain pipe. Therefore, it can prevent the liquid explosive from contacting water and drain the water in the water-bearing hole at the same time.

[0013] 2. This utility model can further improve the stability of the waterproof tape and the isolation effect between the waterproof tape and the water-bearing hole by designing the fixing component. Attached Figure Description

[0018] The following is in conjunction with the appendix Figures 1-6 The present invention will be further described below.

[0019] To address the problems existing in the background art, this application proposes the following technical solution: a liquid explosive pump filling structure in a water-containing hole.

[0020] In specific technical solutions, such as Figure 1 and Figure 2 As shown, it includes a sealing section 1, a waterproof strip 2, and a fastener 3.

[0021] In the specific implementation, the sealing section 1 is located outside the water-bearing hole 4, and the charging section 5 is formed between the inner wall of the water-bearing hole 4 and the end of the sealing section 1.

[0022] Furthermore, the waterproof strip 2 is located inside the charging section 5. The waterproof strip 2 is used to contain liquid explosives, isolate the water in the water-bearing hole 4, and expand and squeeze out the water in the water-bearing hole 4. Three through holes are opened in the sealing section 1. Drain pipe 6, injection pipe 7 and detonating cord 8 are installed in the three through holes respectively. The end of the drain pipe 6 is located outside the waterproof strip 2 inside the charging section 5. The drain pipe 6 is used to drain the water in the water-bearing hole 4. The ends of the injection pipe 7 and the detonating cord are located inside the waterproof strip 2. The waterproof strip 2 is initially flat. Liquid explosives can be drawn into the waterproof strip 2 through the pump body and the injection pipe 7. The waterproof strip 2 gradually expands, thereby squeezing out the water in the water-bearing hole 4 and discharging it through the drain pipe 6. Furthermore, the fastener 3 is used to fix the inlet end of the waterproof strip 2 so that the inside of the waterproof strip 2 is sealed, thus preventing water from entering the waterproof strip 2 from the water-containing hole 4, thereby preventing the liquid explosive from coming into contact with and mixing with water.

[0023] When in use, the waterproof tape 2 is sent to the bottom of the hole using the installation pipe. The bottom section of the waterproof tape 2 is sealed. The injection end of the waterproof tape 2 is tied tightly with the injection pipe 7 and the detonating cord 8. Before injection, the waterproof tape 2 is flat. The injection is pumped through the injection pipe 7. The waterproof tape 2 expands continuously, squeezing the water accumulated in the hole and draining it out through the drain pipe 6.

[0024] Example 1 In specific implementations, such as Figure 2 and Figure 3 As shown, the fastener 3 is a rope 301. The rope 301 can be used to tie the end of the waterproof tape 2. The rope 301 can be used to quickly fix the end of the waterproof tape 2 and is easy to obtain.

[0025] Example 2 In specific implementations, such as Figures 3-6 As shown, the fixing component 3 includes a fixing block 311 and an mounting ring 312. The fixing block 311 is fixedly installed on the sealing section 1. The mounting ring 312 is provided with an annular clip 9 and a slot 10. The annular clip 9 corresponds to the slot 10. The annular clip 9 and the slot 10 are engaged to fix the end of the waterproof tape 2 in the slot 10. The opening of the waterproof tape 2 is attached to the fixing block 311. Then, the mounting ring 312 is used to press down the outside of the opening and engage the annular clip 9 with the slot 10, thereby stably fixing the waterproof tape 2 and further improving the isolation effect between the waterproof bag and the water-containing hole 4.

[0026] Furthermore, the through hole where the injection tube 7 and the detonating cord 8 are located extends through to the surface of the fixing block 311.

[0027] Furthermore, the end of the annular clip 9 is a protruding head 11, which allows the annular clip 9 to be stably engaged with the slot 10.

[0028] Furthermore, the protruding head 11 has an arc-shaped edge, which facilitates its insertion into the slot 10.
