Forming charges with cellular air intervals in the drowned chinks
The authors show the ways to form charges with explosive substances having air intervals in drowned chinks in the quarry of building materials. They consider the variants of formation for various static levels of water concerning an installation level of an air interval. The dependences for calculating an allowable height of drowning a cellular pole are determined, with the top part of the charge not emerging.
