[0002] The deep hole blasting device used in lead and zinc mining is a blasting device used in underground mines. It drills holes in the ore body, fills the holes with blasting agents, and applies blasting to break the ore. This device optimizes the efficiency and safety of ore mining.

[0003] The deep hole blasting device used in lead and zinc mining in the prior art requires first drilling a hole in the ore body, then inserting a catheter into the hole, and finally filling the catheter with explosives. However, a small amount of water will accumulate in the drilled hole due to penetration of the hole wall or contact with the aquifer. When the catheter is inserted into the hole, the water will penetrate into the pipe, causing the water to come into direct contact with the explosive, resulting in a decrease in the performance of the explosive, causing the blasting effect to deteriorate, and thus reducing the degree of ore crushing.

[0004] To this end, we provide a deep hole blasting device for lead-zinc ore mining to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Specific embodiment 1

[0028] See also Figure 1-5 The utility model is a deep hole blasting device for lead and zinc mine mining, comprising a catheter 1, an inner cavity of the catheter 1 is provided with an explosive bag 2, and a positioning partition 3 is fixedly connected to the bottom of the inner cavity of the catheter 1; a water squeezing component is provided in the inner cavity of the catheter 1, and the water squeezing component includes a piston cylinder 4, which is slidably connected to the inner cavity of the catheter 1, and an extrusion spring 5 is fixedly connected to the bottom of the piston cylinder 4. One end of the extrusion spring 5 is fixedly connected to an upper water squeezing block 6, and the bottom of the upper water squeezing block 6 is fixedly connected to a sponge 7, and the bottom of the sponge 7 is fixedly connected to a lower water squeezing block 8, and a check piece is provided in the inner cavity of the positioning partition 3; a limiting component is provided at the top of the inner cavity of the catheter 1, and the limiting component includes a threaded sleeve 9, which is threadedly connected to the top of the inner cavity of the catheter 1, a limiting cap 10 is fixedly connected to the top of the threaded sleeve 9, and a sealing ring 11 is fixedly connected to the bottom of the limiting cap 10.

[0029] Specifically: the center of the inner cavity of the positioning partition 3 is hollow, so that both ends of the catheter 1 are open. The piston cylinder 4, the upper water squeezing block 6 and the lower water squeezing block 8 are fixedly connected with sealing gaskets to squeeze out the accumulated water. The sponge 7 is a polyurethane sponge with good water absorption and is not easily saturated. The function of the sponge 7 is to absorb the small amount of water that penetrates the surface of the lower water squeezing block 8, so the amount of water required to be absorbed is small and it is not easily saturated. There are holes inside the polyurethane sponge, and it has high hardness and small deformation. Therefore, when there is accumulated water at the bottom of the lower water squeezing block 8, the sponge 7 will not be affected. The sealing ring 11 can seal the interface between the limiting cap 10 and the catheter 1 to prevent moisture penetration. Specific embodiment 2

[0031] See also Figure 1-5 On the basis of the specific embodiment 1, the return member includes a spring rod 12, which is fixedly connected to both sides of the inner cavity of the positioning partition 3, one end of the spring rod 12 is fixedly connected to an inclined block 13, both sides of the bottom of the lower water squeezing block 8 are fixedly connected to a clamping block 14, the top of the piston cylinder 4 is fixedly connected to a connecting ring 15, the inner cavity of the connecting ring 15 is fixedly connected to a fuse rope 16, the surface of the fuse rope 16 is fixedly connected to the inner cavity of the explosive bag 2, the inner cavity of the limiting cap 10 is opened with a circular hole, the inner cavity of the circular hole extends to the inside of the catheter 1, and the fuse One end of the rope 16 extends to the outside of the catheter 1 through the inner cavity of the circular hole. Square holes are provided on the tops of both sides of the positioning partition 3. The bottom of the clamping block 14 is slidably connected to the inner cavity of the positioning partition 3 through the inner cavity of the square hole. A clamping groove is provided at the bottom of one side of the clamping block 14. One side of the inclined block 13 is slidably connected to the inner cavity of the clamping groove. An internal thread 17 is provided at the top of the inner cavity of the catheter 1. The surface of the threaded sleeve 9 is threadedly connected to the inner cavity of the catheter 1 through the internal thread 17. Balance rods 18 are fixedly connected to both sides of the top of the piston cylinder 4. There are two balance rods 18.

[0032] Specifically: After one side of the blocking block 14 is connected to the inclined block 13, it can prevent the piston cylinder 4 from moving toward the inner cavity of the catheter 1, thereby ensuring that moisture does not re-enter the catheter 1 and ensuring that the explosive packs 2 are evenly placed. The function of the extrusion spring 5 is to enable the upper water squeezing block 6 and the lower water squeezing block 8 to prevent the piston block from moving in the opposite direction through the reverse restriction provided by the extrusion spring 5 during the water squeezing process. The fuse rope 16 is made of high-strength synthetic fiber and has the characteristics of heat resistance, wear resistance and tensile strength to prevent it from breaking when pulled. The limit cap 10 can be installed at one end of the catheter 1 through the internal thread 17 and the threaded sleeve 9. The two push rods can push the piston cylinder 4 at the same time through the balance rod 18 to ensure the smoothness of the push.

[0033] The working principle of the present invention is as follows: when it is necessary to carry out mining blasting on lead-zinc ore, firstly, the conduit 1 is placed in a pre-drilled hole, and then the explosive pack 2 installed according to the specific situation is fixed on the surface of the fuse rope according to calculation, and one end of the fuse rope 16 is fixed to the connecting ring 15 of the piston cylinder 4, and then connected to the two external push rods through the balance rod 18.

[0034] Then the piston cylinder 4 can be pushed by the push rod, and the piston cylinder 4 drives the extrusion spring 5, the upper water squeezing block 6, the sponge 7 and the lower water squeezing block 8 to move. During the movement, the lower water squeezing block 8 can squeeze the accumulated water that penetrates into the inside of the catheter 1, and the sponge 7 and the upper water squeezing block 6 can isolate and absorb a small amount of water that penetrates through the lower water squeezing block 8, thereby drying the inside of the catheter 1. When the card block 14 at the bottom of the lower water squeezing block 8 extends to the inner cavity of the positioning partition 3 and squeezes the inclined block 13, the elasticity of the spring rod 12 causes the inclined block 13 to bounce to the inner cavity of the card block 14, and then the pushing of the piston cylinder 4 can be stopped.

[0035] At this time, the push rod is moved out, and the threaded sleeve 9 at the bottom of the limiting cap 10 is screwed into the catheter 1 along the internal thread 17 of the inner cavity of the catheter 1, so that the bottom of the sealing ring 11 fits with the opening of the catheter 1, and finally the fuse rope 16 is pulled to lay the explosive package 2 flat inside the catheter 1, and the fuse rope 16 is fixed. The explosive package 2 is set on the center line of the inner cavity of the catheter 1 through the limiting cap 10 to ensure the quality of the explosion. In this way, the explosive package 2 can be detonated by the external controller to carry out blasting.

Therefore, the control method and circuit connection are no longer explained in detail in the present invention.
