Performing different works (construction of road embankments, canals, tunnels, moving some soil mass in a given direction), as well as construction of various towers, power transmission supports, foundations for bridge supports, special pits for anchors are carried out by explosive technologies. The paper analyzes in detail a new method of determining the boundary of the explosion excavation. Its distinguishing features are the use of an impulse-hydrodynamic model for setting explosion problems and use of boundary problems of the theory of analytical functions. The new method is used in solving the problem of determining the boundary of the ejection excavation for the case of a buried charge. The results of calculations for the main geometric parameters of the explosion are given. The prospects for the development and application of the method are discussed.
Key words: road embankments / canals / explosive technologies / cord charges / impulse / complex potential
