Description

During blasting, it is necessary to first drill a hole in the rock wall, then fill the hole with explosives, seal the hole mouth with a mud plugging rod, and then ignite and blast. When charging, the smaller the charging density, the larger the volume when the explosion occurs, so the initial pressure of the gas expansion is smaller, and the resulting blasting strength is low. There are various explosive filling devices in the existing technology. For example, the Chinese new utility model with patent number CN201711256966.1 discloses an underground blasthole explosive filling and compacting device.
