In article the problem of the interaction of two flat cord charges at explosion on the ground surface is considered. The impulse-hydrodynamic solid-liquid model is used. The action of charges on the medium by the pressure pulse is determined. The boundary of the ejection crater is a surface with some constant speed module value. It is believed that in general the charges have different widths and pressure pulses characterizing the effect of charges on the medium may be different. The exact solution to the problem is built by displaying the areas of change complex potential and complex speed per area of change auxiliary parametric variable. Detailed parametric analysis done for the case of equal charges. The behavior of the solution when changing the main dimensionless parameters is learned. Limitations on values of determining parameters are specified. Limiting cases is investigated. The results of calculations of the shape of the ejection crater for various sets of values of defining parameters are given.
Keywords: explosion, crater of an ejection, flat surface cord charges, inviscid incompressible fluid, pulse-hydrodynamic model.
