Abstract

The invention provides a deep hole blasting fast charging device and a charging method. The charging device is formed by connecting multiple charging units connected end to end. Each charging unit comprises a charging tube, a detonating cord and an explosive roll. Sealing stoppers are arranged at the head portion and the tail portion of the charging device correspondingly, and the sealing stopperat the head portion has a sealing effect and also has a through hole assisting effect. When charging is conducted, the assembled charging device is overall taken off from a hook, then the charging device is rapidly pushed into a drill hole through manual work, then a through hole device is used for overall pushing the charging device to the preset position of the drill hole again, and therefore the fast pushing effect is achieved. The charging method is also fast, and therefore the phenomenon that potential safety hazards are brought due to long-time high-strength work when field constructorsdo construction on a construction platform can be well avoided, the overall work efficiency can be improved, and meanwhile the construction safety and detonation effect can also be well ensured.

Description

technical field [0001] The invention belongs to the technical field of coal mining blasting, and in particular relates to a fast charging device and a charging method for deep hole blasting. Background technique [0002] At present, the charging method of deep-hole blasting in coal mines is to push explosives into the hole one by one, and then connect the detonators in stages. In deep-hole blasting, due to the large hole depth and the large number of powder rolls, it needs to be repeated many times. Pushing the drug roll every time will inevitably lead to low overall charging efficiency. Usually, a 30m deep hole only needs 3-4 hours for the charging process, which takes a long time for charging and the staff need to spend a long time on the construction platform Head-up operation, resulting in high labor intensity, resulting in fatigue psychology, and then the sense of responsibility and safety awareness will decline, the implementation of safety technical measures for charg...
