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

The invention relates to the technical field of engineering blasting, and particularly discloses an automatic processing device for blast holes with karst caves. The automatic processing device comprises a capsule, a telescoping mechanism and a fixed box; the telescoping mechanism is arranged in a space in the capsule; the top of the telescoping mechanism is fixed with the top of the capsule; thetelescoping mechanism can stretch along the horizontal direction; a plunger is fixed at the lower end of the telescoping mechanism; the fixed box is fixed to the bottom of the capsule; a water inlet hole matched with the plunger is arranged on the fixed box; the fixed box communicates with the interior of the capsule through the water inlet hole; an oxygen generating agent is filled in the fixed box, and the oxygen generating agent is in contact with water to generate a large amount of oxygen; the capsule is filled with water; a first pull rope is fixed to the top of the telescoping mechanism;scales are arranged on the first pull rope; a second pull rope is fixed to the bottom of the telescoping mechanism; and the first pull rope and the second pull rope vertically and upwards penetrate through the top of the capsule and are in sliding sealing connection with the capsule. The invention aims to solve the problem that the effect is poor when a woven bag is adopted to block the blast holes.

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...
