Embodiment Construction

[0026] The following is further described in detail through specific implementation methods:

[0027] The reference signs in the accompanying drawings include: rock 10, blast hole 11, cave 12, capsule 20, fixed block 21, partition 22, first hinge shaft 221, first connecting rod 231, second connecting rod 232, Plunger 24, fixed box 25, sodium peroxide 251, first stay cord 26, second stay cord 27, second hinge shaft 28.

[0028] The embodiment is basically as attached figure 1 - attached image 3 Shown: the automatic processing device for blastholes with karst caves, including a capsule body 20, a telescopic mechanism and a fixing box 25.

[0029] like figure 1 As shown, a blasthole 11 is opened in the rock 10, and a karst cave 12 is located in the middle of the blasthole 11, and the karst cave 12 divides the blasthole 11 into upper and lower parts. If there is no karst cave 12 in the inside of blast hole 11, when charging (for the blast hole that the aperture is D90mm deep ...

Abstract

This application relates to the technical field of engineering blasting, and specifically discloses an automatic processing device for blastholes with karst caves, including a capsule, a telescopic mechanism, and a fixing box. Fixed, the telescopic mechanism can expand and contract in the horizontal direction, the lower end of the telescopic mechanism is fixed with a plunger; the bottom of the capsule body is fixed with a fixed box, and a water inlet hole matching the plunger is opened on the fixed box, and the fixed box connects with the capsule through the water inlet hole. The inside of the body is connected; the fixed box is equipped with an oxygen generating agent, and the oxygen generating agent can generate a large amount of oxygen in contact with water; the inside of the capsule body is filled with water; Scale, the bottom of the telescoping mechanism is fixed with a second stay cord, the first stay cord and the second stay cord pass through the top of the capsule vertically upwards and are slidably and sealedly connected with the capsule. The purpose of this patent is to solve the problem of poor effect of using woven bags to block blastholes.

Description

technical field [0001] The invention relates to the technical field of engineering blasting, in particular to an automatic processing device for blastholes with karst caves. Background technique [0002] In the field of engineering construction, the role of blasting technology is extremely critical. Generally, shallow, medium and deep hole blasting methods are adopted. In medium and deep hole blasting, there are cases where karst caves exist inside the rock formation. During the operation, if the specific position and size of the cave area are not detected in time, a large amount of explosives will be wasted in the subsequent explosive loading process, and when excessive explosives are loaded in the blast hole, the blasting effect will be affected, and some explosives may not be timely The explosion brought serious safety hazards to the subsequent mining work. [0003] In addition, the current treatment method for blastholes with karst caves is to divide the blastholes in...
