Problems solved by technology

[0004] ①The safety guarantee is low, and it is impossible to ensure that the drug string can reach the predetermined hole depth smoothly. When adjusting the position of the drug package in the hole, it is easy to get stuck when entering the hole or pulling up. When the upward pulling force is too large, it is easy to cause damage to the drug string or even the pull rope.
When rubbing against the hole wall up and down, it is easy to accidentally drop the powder string or the detonator and damage the gun line
[0005] ②It is not easy to detect. After measuring the length of the entire drug string and the distance between the drug packs, if you need to adjust the length of the drug packs and the distribution spacing, you need to repeat the steps of bundling and testing, which is time-consuming and troublesome
[0007] ④No waterproof and moisture-proof function
[0009] ① low efficiency
Bamboo boards need to be fixed in series at the construction site in advance, especially for deep-hole blasting, which requires a long bamboo board, which consumes more manpower and working time, requires a large number of professionals during the operation, and requires the cooperation of multiple people when putting the explosive string into the blast hole Operation
[0010] ②The safety guarantee is not high
In the process of putting the medicine string into the deep blast hole, the bamboo board is prone to break and the bamboo board falls out of the hand, causing a stall and falling into the hole. If the bamboo board is too short and completely falls into the hole, it will be difficult to salvage. The friction between the bamboo board (joint) and the hole wall is easy to wear the exposed detonator wire, causing line failure
[0011] ③No waterproof and moisture-proof function

Embodiment 1

[0043] A charge and sounding device for auxiliary mine smooth blasting, such as Figure 1-6 As shown, it includes a flexible covering body 1 wrapped outside the explosive package, and the flexible covering body is provided with longitudinal keel ribs 2 distributed along the length direction of the explosive package, and the flexible covering body 1 is uniformly distributed along the length direction of the explosive package. Rope holes 3 are arranged at intervals, and the fixed binding rope 4 passes through the rope holes and wraps around the flexible covering body 1 at least once along the width direction of the explosive pack to bind the flexible covering body outside the explosive pack. Wherein, the rope holes 3 are distributed on both sides of the flexible covering body close to the edge, and two longitudinal keel bars 2 are set in the middle of the flexible covering body 1 . In this embodiment, the flexible covering body 1 adopts a chemical fiber mesh surface. The longit...

Embodiment 2

[0048] Embodiment 2: A charge and sounding device for assisting mine smooth blasting in this embodiment will be described centering on the differences from Embodiment 1.

[0049] Such as Figure 7 As shown, the rope hole 3 on one side of the flexible covering body 1 is replaced by a sub-glue 7 , and the female hook-and-loop fastener 8 matching the sub-glue 7 is located between the two rope holes on the other side of the flexible covering body. Can further increase work efficiency.

Embodiment 3

[0050] Embodiment 3: A charge and sounding device for assisting mine smooth blasting in this embodiment will be described centering on the differences from Embodiment 1.

[0051] Such as Figure 8 As shown, the flexible covering body 1 adopts a waterproof cloth, and waterproof zippers 13 are installed on both sides of the waterproof cloth, and the waterproof zipper 13 is closed to wrap the waterproof cloth outside the explosive bag. The rope hole 3 is sewn on the outer surface of the tarpaulin, and the fixed binding rope 4 passes through the rope hole 3 to bind the tarpaulin outside the explosive bag. Applicable to wet construction environment, waterproof and moisture-proof.

Abstract

The invention relates to an explosive charging and sounding device assisting in mine smooth blasting. The explosive charging and sounding device comprises a flexible coating body coating a satchel charge. The flexible coating body is provided with a longitudinal keel ribs distributed in the length direction of the satchel charge. Rope holes are formed in the flexible coating body evenly at intervals in the length direction of the satchel charge. A fixing tying rope penetrates through the rope holes and surrounds the flexible coating body by at least round in the width direction of the satchelcharge so as to tie the flexible coating body outside the satchel charge. The flexible coating body is provided with sounding strips distributed in the length direction of the satchel charge. The sounding strips are composed of coloration lattices distributed at intervals. The coloration lattices and the flexible coating body are different in color, and the height of each coloration lattice is equal to the distance between the two corresponding adjacent coloration lattices. Through the explosive charging and sounding device, accidental detonator falling and accidental explosive cluster hole-falling can be prevented effectively, a hole depth detection function is added, and smooth construction operation is ensured.

Description

technical field [0001] The invention relates to the technical field of smooth blasting, in particular to a charge and a sounding device for assisting smooth blasting in mines. Background technique [0002] At present, the following two methods are generally used when charging mine smooth blasting: [0003] The first one is to tie the explosive strings on soft ropes such as nylon ropes and put them in the blast holes. This method has the following disadvantages: [0004] ①The safety guarantee is low, and it is impossible to ensure that the drug string can reach the predetermined hole depth smoothly. When adjusting the position of the drug package in the hole, it is easy to get stuck when entering the hole or pulling up. When the upward pulling force is too large, it is easy to cause damage to the drug string or even the pull rope. . When rubbing against the hole wall up and down, it is easy to accidentally drop the powder string or the detonator and damage the gun line. ...
