specific Embodiment approach 1

[0008] Specific implementation mode one: combine figure 1 with figure 2 Describe this embodiment, the blasting charging device of this embodiment includes a guide head 1, a transition pipe 2, a plurality of drug delivery devices 7, a drug chamber sealing pipe collar 5, a plurality of sealing connection devices 8, a grouting pipe 11 and two A detonating cord 12, the front end of the guide head 1 is hemispherical, and the rear part is tubular. Each drug delivery device 7 is composed of a first two-way positioning collar 3 and two guide pieces 4. Each first two-way positioning The pipe walls at both ends of the pipe collar 3 are respectively provided with a first annular positioning groove 3-1, and one end of the two guide pieces 4 is installed in one of the two first annular positioning grooves 3-1, and the two guide pieces 4 Contact and form a round tube 4-2, the tube wall of each guide piece 4 is provided with an elongated through hole 4-1, two elongated through holes 4-1 on...

specific Embodiment approach 2

[0009] Specific implementation mode two: combination figure 1 This embodiment will be described. The hemispherical diameter of the front end of the guide head 1 in this embodiment is 10mm-20mm smaller than the diameter of the blast hole. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0010] Specific implementation mode three: combination figure 1 Describe this embodiment, the width of the first annular positioning groove 3-1 near the head of the drug delivery device 7 of the two-way positioning tube collar 3 of this embodiment of this embodiment gradually decreases from the head to the tail along the two-way positioning tube collar 3, and the two-way The width of the first annular positioning groove 3-1 near the end of the drug delivery device 7 in the positioning collar 3 gradually decreases from the tail to the head along the axial direction of the bidirectional positioning collar 3. The advantage of this connection structure is that it is compatible with the transition tube or positioning The pieces are tightly connected. Other components and connections are the same as those in the first embodiment.

Abstract

The invention discloses a long borehole blast charging device and a method, which relate to a blast charging device and a method, and aim at the problems that the existing long borehole blast charging device has a high charging temperature and anti-powder rate phenomena, and when yellow mud particles are adopted for hole sealing, the cohesive force between the yellow mud particles and a blast hole is mall. The device adopts the technical scheme that: a guiding head is connected with a transition pipe; the transition pipe is connected with head parts of a plurality of powder feeding devices which are connected with one another end to end in turn; the tail parts of the plurality of the powder feeding devices are arranged in a sealing pipe hoop of a powder chamber; the head parts of a plurality of hole sealing connecting devices are arranged in the sealing pipe hoop of the powder chamber; and the plurality of the hole sealing connecting devices are connected with one another end to end in turn; the tail parts of the plurality of the hole sealing connecting devices are hole sealing pipes; grouting pipes are arranged in a plurality of hole sealing pipe connecting devices; and an explosive is placed between two guiding plates. The method adopts the technical scheme of using a long borehole blast charging method by using the device and comprises the following steps of: step one to step five, connecting the charging device according to the technical scheme of the device; step six, performing grouting; and step seven, performing detonation. The device and the method are used for borehole blasting.

Description

technical field [0001] The invention relates to a blasting charge device and method. Background technique [0002] The existing long-hole blasting device uses a charge machine to charge and seal the hole. The temperature of the charge is high and there is a phenomenon of anti-powder rate. When the hole is sealed with yellow mud particles, the bonding force between the yellow mud particles and the blast hole is small. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the charging temperature of the existing long-drilled blasting device is relatively high, there is a phenomenon of anti-powder rate, and when the yellow mud particles are used to seal the holes, the bonding force between the yellow mud particles and the blasting hole is small. A long drilling and blasting charge device and method. [0004] The technical scheme adopted by the present invention to solve the above technical problems is: device scheme: the blastin...
