EXPLOSIVE DISPERSAL DEVICE Russian patent published in 2023 - IPC F42D1/08 F42D1/20 

FIELD: mining, mining industry, drilling, blasting and construction work.

SUBSTANCE: explosive dispersal device includes a post, a support mounted on the submersible part of the post, a downhole gate located on the mounting part of the post. At least one hole is made in the post wall, connected to its inner channel and located between the support and the downhole gate. The shutter contains at least two elastic membranes, each of which has at least one radial cut. The membranes are made superimposed on each other. The method for installation of explosive dispersal device includes installation of a downhole gate on the mounting part of the post, installation of a support on the submersible part of the post, making at least one hole in the wall of the post with a channel previously formed inside it between the support and the downhole gate of the post, installation of a device for dispersing explosive substances into the well. In this case, the shutter is made with at least two elastic membranes, in each of which at least one radial cut is made. The membranes are made superimposed on each other. The explosive is placed on the downhole gate.

EFFECT: increase of efficiency of drilling and blasting by improving the accuracy of the installation of the device for dispersing the explosive, as well as ensuring the formation of water-air gaps in the drilling without displacement of the contact area of the installation of the device.
