Description

Technical Field

[0001] The present invention belongs to the technical field of mine blasting, and more specifically, relates to a deep-water blasthole charging device. The present invention also relates to a deep-water blasthole charging method. Background Art

[0002] At present, in open-pit mining operations, due to environmental climate or geological conditions, there is often severe water accumulation in the blasthole after the drill rig drills the hole. The occurrence of water accumulation causes the rock emulsion explosive to be unable to sink to the bottom of the hole or the specific position required by the technology due to the buoyancy of the water in the hole, affecting the subsequent charging amount, charging length and filling length, and ultimately affecting the blasting effect or causing a blasting accident. In the prior art, mines usually use bamboo poles or wooden sticks to press the emulsion explosives into the bottom of the hole in sections or multiple sections, and then quickly fill the hole; or first use a water pump to pump water from the hole one by one, and then load and fill. Although this method can solve the problem of water accumulation in the hole to a certain extent, it is labor-intensive, has low charging efficiency, and poses safety risks. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in view of the shortcomings of the prior art, a device is provided which has a simple structure and can safely and reliably realize the loading of explosives into blastholes with accumulated water, so that the explosives can effectively overcome the buoyancy of water and reach the set loading position, thereby solving the difficulties of the prior art such as the difficulty in charging blastholes with accumulated water and the inadequate charging, and ultimately achieving high charging efficiency, significantly reduced labor intensity of construction personnel, and accurate subsequent blasting in deep-water blastholes.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0005] The present invention discloses a deep-water blasthole charging device, which comprises a hollow outer rod and a telescopic connecting rod. One end of the telescopic connecting rod is movably sleeved on one end of the outer rod. A fixing screw is screwed into a threaded hole on the outer rod. A counterweight head rubber is arranged at the other end of the outer rod. A counterweight head is arranged inside the counterweight head rubber. A buoyancy tail rubber is arranged at the other end of the telescopic connecting rod. A pulley base is arranged on the outer rod near the counterweight head rubber. A freely rotatable pulley is installed on the pulley base. A traction rope passes around the pulley. An explosive binding part is arranged on the traction rope.

[0006] The telescopic connecting rod is configured as a structure capable of being telescopic relative to the outer rod, and the fixing screw is configured as a structure capable of penetrating the outer rod and contacting the telescopic connecting rod.

[0007] A plurality of protruding counterweight head rubber tentacles are arranged on the outer side of the counterweight head rubber; a plurality of protruding tail rubber tentacles are arranged on the outer side of the buoyancy tail rubber.

[0008] When the deep-water blasthole charging device is placed in the blasthole to install explosives, both ends of the traction rope are configured to be able to extend to a position outside the blasthole.

[0009] The traction rope is provided with scale marks.

[0010] When the deepwater blasthole charging device is placed in the blasthole to install explosives, when the ends of the traction rope are pulled upward at the same time, the counterweight head rubber of the deepwater blasthole charging device is set to a structure that can be clamped on the inner wall of one side of the blasthole, and the buoyancy tail rubber is set to a structure that can be clamped on the inner wall of the other side of the blasthole.

[0011] The length dimension between the rubber outer side of the counterweight head and the rubber outer side of the buoyancy tail of the deep-water blasthole charging device is set to be larger than the diameter dimension of the blasthole.

[0012] When the counterweight head rubber and the buoyancy tail rubber of the deepwater blasthole charging device are clamped on the inner wall of the blasthole, the outer rod and the telescopic connecting rod of the deepwater blasthole charging device are both arranged to be in an inclined state.

[0013] The present invention also relates to a method for safely and reliably loading explosives into a blasthole with accumulated water, which has simple steps and can effectively overcome the buoyancy of water and reach a set charging position, thereby solving the problems of difficulty in charging explosives into blastholes with accumulated water and inadequate charging in the prior art, and finally achieving high charging efficiency, significantly reducing the labor intensity of construction personnel, and accurately charging deep-water blastholes for later blasting. The charging method is as follows:

[0014] 1) Loosen the fixing screws and adjust the position of the telescopic connecting rod relative to the outer rod according to the size of the borehole diameter, so that the length between the rubber outer side of the counterweight head of the deepwater borehole charging device and the rubber outer side of the buoyancy tail is greater than the borehole diameter. After determining the length, tighten the fixing screws and pass the traction rope around the pulley;

[0015] 2) The operator holds the ends of the traction rope and puts the deep-water blasthole charging device into the blasthole. Do not pull the ends of the traction rope before the deep-water blasthole charging device reaches the designated position;

[0016] 3) When the deepwater blasthole charging device reaches the designated position, pull up both ends of the traction rope at the same time, slowly and forcefully, until the rubber clamp of the counterweight head of the deepwater blasthole charging device is mounted on the inner wall of one side of the blasthole, and the rubber clamp of the buoyancy tail is mounted on the inner wall of the other side of the blasthole, and the deepwater blasthole charging device and the blasthole are positioned;

[0017] 4) Explosives are bundled on one end of a traction rope provided with an explosive bundling part. After bundling, the other end of the traction rope is slowly pulled upward. At this time, the explosives move downward in the blasthole along with the movement of the traction rope until the explosives reach the designated position, thereby completing the deep-water blasthole charging.

[0018] After the explosive moves down in the blast hole until it reaches the designated position, the ends of the traction rope are fixed outside the blast hole to realize the positioning of the explosive.

[0019] By adopting the technical solution of the present invention, the following beneficial effects can be obtained:

[0020] The deepwater blasthole charging device and charging method described in the present invention propose a new technical solution for the situation in which buoyancy is generated by water accumulation in the blasthole in the prior art. By using the coordination of the traction rope and the pulley of the deepwater blasthole charging device, the deepwater blasthole charging device can be conveniently and reliably placed at the bottom of the blasthole or the set position to achieve positioning with the blasthole, forming a fulcrum that can meet the up and down movement of the traction rope in the blasthole. On the other hand, through the movement of the traction rope relative to the pulley, the traction rope can be tied tightly to the explosive, thereby driving the explosive to move downward in the blasthole until the explosive is moved to the set position. During the movement of the explosive, the traction rope can reliably apply force to effectively overcome the buoyancy, so that the explosive can be moved into place conveniently, quickly and accurately, reducing the difficulty of charging and ensuring the accuracy of the later blasting. When charging, loosen the fixing screws, adjust the position of the telescopic connecting rod relative to the outer rod according to the diameter of the borehole, so that the length from the rubber outer side of the counterweight head to the rubber outer side of the buoyancy tail of the deepwater borehole charging device is greater than the borehole diameter. After determining the length, tighten the fixing screws and let the traction rope pass around the pulley; the operator holds the two ends of the traction rope and puts the deepwater borehole charging device into the borehole. Do not lift or pull the two ends of the traction rope when the deepwater borehole charging device has not reached the specified position; during the placement process, since the traction rope itself is eccentrically connected and the weight of the counterweight head is greater than the buoyancy tail rubber, the deepwater borehole charging device is always in a tilted state during the descent. When the deepwater blasthole charging device reaches the designated position, the ends of both ends of the traction rope are pulled upward at the same time, and the pull is slowly applied. Since the deepwater blasthole charging device is always in an inclined state and the length of the deepwater blasthole charging device is larger than the diameter of the blasthole, the deepwater blasthole charging device will rest against the inner wall of the blasthole after applying an upward pulling force, so that the counterweight head rubber card of the deepwater blasthole charging device can be easily installed on the inner wall of one side of the blasthole, and the buoyancy tail rubber card is installed on the inner wall of the other side of the blasthole. In this way, the deepwater blasthole charging device and the blasthole are positioned; and the explosives are bundled at one end of the traction rope where an explosive bundling part is provided. After bundling is completed, the other end of the traction rope is slowly pulled upward. At this time, the explosives move down in the blasthole with the movement of the traction rope until the explosives reach the designated position, and the deepwater blasthole charging is completed. In this way, the device and method of the present invention can be widely used in deep hole blastholes in open-pit mines or underwater blasting charging, and can be reliably used when there is a lot of water in vertical blastholes and inclined blastholes. By adopting the technology of the present invention, explosives can be easily and accurately loaded into water-logged blastholes, avoiding the situation that the explosives cannot be loaded into the designed position due to the buoyancy of water or the intervals between the explosives are too large, thereby preventing the blasting effect from being affected and even causing the occurrence of blind or residual shots.The deepwater blasthole charging device and charging method described in the present invention have a simple device structure and simple method steps, and can safely and reliably realize the charging of explosives into blastholes with accumulated water, so that the explosives can effectively overcome the buoyancy of water and reach the set charging position, thereby solving the difficulties of charging blastholes with accumulated water and inadequate charging in the prior art, and ultimately achieving high charging efficiency, significantly reducing the labor intensity of construction personnel, and accurate blasting in the later stage.

DETAILED DESCRIPTION

[0027] The following is a further detailed description of the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various components involved, the function and working principle of each part, etc., through the description of the embodiments with reference to the accompanying drawings:

[0028] As attached Figure 1 -Attached Figure 4As shown, the present invention is a deep-water blasthole charging device, comprising a hollow outer rod 1, a telescopic connecting rod 2, one end of the telescopic connecting rod 2 is movably sleeved on one end of the outer rod 1, a fixing screw 3 is screwed into a threaded hole on the outer rod 1, a counterweight head rubber 4 is arranged at the other end of the outer rod 1, a counterweight head 5 is arranged inside the counterweight head rubber 4, a buoyancy tail rubber 6 is arranged at the other end of the telescopic connecting rod 2, a pulley base 7 is arranged on the outer rod 1 near the counterweight head rubber 4, a pulley 8 that can rotate freely is installed on the pulley base 7, a traction rope 9 passes around the pulley 8, and an explosive binding part is arranged on the traction rope 9. In view of the situation in the prior art that the blasthole 12 has water accumulation and generates buoyancy, a new technical solution is proposed. By using the coordination of the traction rope and the pulley of the deepwater blasthole charging device, the deepwater blasthole charging device can be conveniently and reliably placed at the bottom of the blasthole 12 or the set position to achieve positioning with the blasthole 12, forming a fulcrum that can meet the up and down movement of the traction rope in the blasthole 12. On the other hand, through the movement of the traction rope relative to the pulley, the explosive can be tied to the traction rope, thereby driving the explosive to move downward in the blasthole 12 until the explosive is moved to the set position. During the movement of the explosive, the traction rope can reliably apply force to effectively overcome the buoyancy, so that the explosive can be moved into place conveniently, quickly and accurately, reducing the difficulty of charging and ensuring the accuracy of the later blasting. When charging, loosen the fixing screw 3, adjust the position of the telescopic connecting rod 2 relative to the outer rod 1 according to the diameter of the blasthole 12, so that the length between the outer side of the counterweight head rubber 4 of the deepwater blasthole charging device and the outer side of the buoyancy tail rubber 6 is greater than the diameter of the blasthole 12, and tighten the fixing screw 3 after determining the length, and the traction rope 9 passes around the pulley 8; the operator holds the two ends of the traction rope 9 and puts the deepwater blasthole charging device into the blasthole 12. Do not pull the two ends of the traction rope 9 when the deepwater blasthole charging device has not reached the specified position; during the placement process, since the traction rope itself is eccentrically connected and the weight of the counterweight head is greater than the buoyancy tail rubber 6, the deepwater blasthole charging device is always in a tilted state during the descent. When the deepwater blasthole charging device reaches the designated position, the ends of the traction rope 9 are pulled upward at the same time, and the pulling is done slowly and forcefully. Since the deepwater blasthole charging device is always in an inclined state, and the length of the deepwater blasthole charging device is larger than the diameter of the blasthole, after applying an upward pulling force, the deepwater blasthole charging device will rest against the inner wall of the blasthole, so that the counterweight head rubber 4 of the deepwater blasthole charging device can be easily mounted on the inner wall of one side of the blasthole 12, and the buoyancy tail rubber 6 is mounted on the inner wall of the other side of the blasthole 12. In this way, the deepwater blasthole charging device and the blasthole 12 are positioned; and the explosive is bundled with the explosive at one end of the traction rope 9, and after the bundling is completed, the other end of the traction rope 9 is slowly pulled upward, and at this time, the explosive moves down in the blasthole 12 along with the movement of the traction rope 9 until the explosive reaches the designated position, and the deepwater blasthole charging is completed.In this way, the device and method of the present invention can be widely used in deep-hole blastholes or underwater blasting in open-pit mines, and can be reliably used when there is a lot of water in vertical blastholes and inclined blastholes. By adopting the technology of the present invention, explosives can be easily and accurately loaded into the blastholes with water accumulation, avoiding the situation that the explosives cannot be loaded to the designed position due to the buoyancy of water or the interval between the explosives is too large, so that the blasting effect will not be affected, and even blind or residual gun phenomena will not be caused. The deep-water blasthole charging device and charging method described in the present invention have a simple device structure and simple method steps. They are used for specific problems, and can safely and reliably realize the charging of explosives in blastholes with water accumulation, so that the explosives can effectively overcome the buoyancy of water and reach the set charging position, solving the difficulties of charging blastholes with water accumulation and charging inadequately in the prior art, and finally achieving high charging efficiency, significantly reducing the labor intensity of construction personnel, and accurate blasting in the later stage, meeting the needs.

[0029] The telescopic connecting rod 2 is configured to be telescopic relative to the outer rod 1, and the fixing screw 3 is configured to be able to penetrate the outer rod 1 and contact the telescopic connecting rod 2. The above structure can change the overall length of the deepwater blasthole charging device by adjusting the relative position of the telescopic connecting rod and the outer rod, so that it is suitable for use in blastholes of different diameters, and the versatility of the device is improved.

[0030] A plurality of protruding counterweight head rubber tentacles 10 are arranged outside the counterweight head rubber 4; a plurality of protruding tail rubber tentacles 11 are arranged outside the buoyancy tail rubber 6. With the above structure, the rubber tentacles can ensure that the device can reliably reach the designated position and be firmly stressed in various types of hole walls and water environments, ensuring that the device can function normally.

[0031] When the deep-water blasthole charging device is placed in the blasthole 12 to install explosives, both ends of the traction rope 9 are configured to extend to the outside of the blasthole 12.

[0032] The traction rope 9 is provided with scale lines. The above structure, through the setting of scale lines, can conveniently and reliably grasp the distance when the traction rope moves up and down, and the explosives can be accurately moved into place.

[0033] When the deepwater gunhole charging device is placed in the gunhole 12 to install explosives, when the ends of the traction rope 9 are pulled up at the same time, the counterweight head rubber 4 of the deepwater gunhole charging device is set to a structure that can be clamped on the inner wall of one side of the gunhole 12, and the buoyancy tail rubber 6 is set to a structure that can be clamped on the inner wall of the other side of the gunhole 12. The length dimension between the outer side of the counterweight head rubber 4 of the deepwater gunhole charging device and the outer side of the buoyancy tail rubber 6 is set to a structure greater than the diameter of the gunhole 12. When the counterweight head rubber 4 and the buoyancy tail rubber 6 of the deepwater gunhole charging device are clamped on the inner wall of the gunhole 12, the outer rod 1 and the telescopic connecting rod 2 of the deepwater gunhole charging device are both set to a structure in an inclined state. In the above structure, during the placement of the deepwater gunhole charging device, since the traction rope itself is eccentrically connected and the weight of the counterweight head is greater than the buoyancy tail rubber 6, the deepwater gunhole charging device is always in an inclined state during the descent process. When the deep-water gunhole charging device reaches the designated position, the ends of the traction rope 9 are pulled upward at the same time, and the pulling force is applied slowly. Since the deep-water gunhole charging device is always in an inclined state, and the length of the deep-water gunhole charging device is larger than the diameter of the gunhole, after applying the upward pulling force, the deep-water gunhole charging device will be against the inner wall of the gunhole, so that the counterweight head rubber 4 of the deep-water gunhole charging device can be easily mounted on the inner wall of one side of the gunhole 12, and the buoyancy tail rubber 6 is mounted on the inner wall of the other side of the gunhole 12. In this way, the deep-water gunhole charging device is positioned with the gunhole 12 and will not be easily separated. With the above structure, after the explosives are loaded in place, the deep-water gunhole charging device does not need to be recycled. Therefore, in use, each deep-water gunhole charging device is placed for one-time use. And the device is mostly made of degradable materials. In this way, it will not affect the operation and is easy to degrade.

[0034] The present invention also relates to a method for safely and reliably loading explosives into a blasthole with accumulated water, which has simple steps and can effectively overcome the buoyancy of water and reach a set charging position, thereby solving the problems of difficulty in charging explosives into blastholes with accumulated water and inadequate charging in the prior art, and finally achieving high charging efficiency, significantly reducing the labor intensity of construction personnel, and accurately charging deep-water blastholes for later blasting. The charging method is as follows:

[0035] 1) Loosen the fixing screw 3, adjust the position of the telescopic connecting rod 2 relative to the outer rod 1 according to the diameter of the blasthole 12, so that the length between the outer side of the counterweight head rubber 4 of the deep-water blasthole charging device and the outer side of the buoyancy tail rubber 6 is greater than the diameter of the blasthole 12, and tighten the fixing screw 3 after determining the length, and the traction rope 9 passes around the pulley 8;

[0036] 2) The operator holds the ends of the traction rope 9 and puts the deep-water blasthole charging device into the blasthole 12. Do not pull the ends of the traction rope 9 before the deep-water blasthole charging device reaches the designated position;

[0037] 3) When the deepwater blasthole charging device reaches the designated position, pull the ends of the traction rope 9 upward at the same time, slowly and forcefully pull until the counterweight head rubber 4 of the deepwater blasthole charging device is clamped on the inner wall of one side of the blasthole 12, and the buoyancy tail rubber 6 is clamped on the inner wall of the other side of the blasthole 12, and the deepwater blasthole charging device and the blasthole 12 are positioned;

[0038] 4) Explosives are bundled at one end of the explosive bundling part provided on the traction rope 9. After bundling, the other end of the traction rope 9 is slowly pulled upward. At this time, the explosives move downward in the blast hole 12 along with the movement of the traction rope 9 until the explosives reach the designated position, thereby completing the deep-water blast hole charging.

[0039] After the explosive moves downward in the blast hole 12 until it reaches the designated position, the ends of the traction rope 9 are fixed outside the blast hole 12 to achieve the positioning of the explosive.

[0040] The deepwater blasthole charging device and charging method described in the present invention propose a new technical solution for the situation in which buoyancy is generated by water accumulation in the blasthole in the prior art. By using the coordination of the traction rope and the pulley of the deepwater blasthole charging device, the deepwater blasthole charging device can be conveniently and reliably placed at the bottom of the blasthole or the set position to achieve positioning with the blasthole, forming a fulcrum that can meet the up and down movement of the traction rope in the blasthole. On the other hand, through the movement of the traction rope relative to the pulley, the traction rope can be tied tightly to the explosive, thereby driving the explosive to move downward in the blasthole until the explosive is moved to the set position. During the movement of the explosive, the traction rope can reliably apply force to effectively overcome the buoyancy, so that the explosive can be moved into place conveniently, quickly and accurately, reducing the difficulty of charging and ensuring the accuracy of the later blasting. When charging, loosen the fixing screws, adjust the position of the telescopic connecting rod relative to the outer rod according to the diameter of the borehole, so that the length from the rubber outer side of the counterweight head to the rubber outer side of the buoyancy tail of the deepwater borehole charging device is greater than the borehole diameter. After determining the length, tighten the fixing screws and let the traction rope pass around the pulley; the operator holds the two ends of the traction rope and puts the deepwater borehole charging device into the borehole. Do not lift or pull the two ends of the traction rope when the deepwater borehole charging device has not reached the specified position; during the placement process, since the traction rope itself is eccentrically connected and the weight of the counterweight head is greater than the buoyancy tail rubber, the deepwater borehole charging device is always in a tilted state during the descent. When the deepwater blasthole charging device reaches the designated position, the ends of both ends of the traction rope are pulled upward at the same time, and the pull is slowly applied. Since the deepwater blasthole charging device is always in an inclined state and the length of the deepwater blasthole charging device is larger than the diameter of the blasthole, the deepwater blasthole charging device will rest against the inner wall of the blasthole after applying an upward pulling force, so that the counterweight head rubber card of the deepwater blasthole charging device can be easily installed on the inner wall of one side of the blasthole, and the buoyancy tail rubber card is installed on the inner wall of the other side of the blasthole. In this way, the deepwater blasthole charging device and the blasthole are positioned; and the explosives are bundled at one end of the traction rope where an explosive bundling part is provided. After bundling is completed, the other end of the traction rope is slowly pulled upward. At this time, the explosives move down in the blasthole with the movement of the traction rope until the explosives reach the designated position, and the deepwater blasthole charging is completed. In this way, the device and method of the present invention can be widely used in deep hole blastholes in open-pit mines or underwater blasting charging, and can be reliably used when there is a lot of water in vertical blastholes and inclined blastholes. By adopting the technology of the present invention, explosives can be easily and accurately loaded into water-logged blastholes, avoiding the situation that the explosives cannot be loaded into the designed position due to the buoyancy of water or the intervals between the explosives are too large, thereby preventing the blasting effect from being affected and even causing the occurrence of blind or residual shots.The deepwater blasthole charging device and charging method described in the present invention have a simple device structure and simple method steps, and can safely and reliably realize the charging of explosives into blastholes with accumulated water, so that the explosives can effectively overcome the buoyancy of water and reach the set charging position, thereby solving the difficulties of charging blastholes with accumulated water and inadequate charging in the prior art, and ultimately achieving high charging efficiency, significantly reducing the labor intensity of construction personnel, and accurate blasting in the later stage.

[0041] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
