Description

Technical field:

[0001] The utility model relates to an energy concentrator, in particular to a blasting energy concentrator, and belongs to the technical field of blasting. Background technology:

[0002] The ore discharge funnel is a small vertical or inclined well excavated from the transport level to the bottom layer of the mining area. It mainly plays the role of ore discharge. The ore discharge funnel plays a key role in the ore flow and discharge operation. During the discharge process, the ore-rock contact surface in the loose body gradually bends into a funnel shape, which helps the slag to flow out smoothly. At present, the slag in underground mines is transported back through the ore discharge funnel, but in the production process, the funnel is often blocked due to reasons such as wet slag and the presence of large pieces of slag.

[0003] In the prior art, a simple explosive bag is often used to dredge the ore discharge funnel by blasting and crushing the blockage point with the explosive bag. During blasting, a support rod is used to support the explosive bag so that the explosive bag is attached to the surface of the ore, and the explosive is used to crush and dredge. Although the blockage point can be dredged by the prior art, due to the low utilization rate of the explosive energy, multiple blasting is often required, and the dredging efficiency is low. Multiple blasting also reduces the safety during operation. Therefore, a blasting concentrator is proposed. Utility model content:

[0004] The purpose of the utility model is to provide a blasting energy concentrator to solve one of the problems raised in the above background technology.
