The parity between length of a crack of hydrobreak and pressure of a liquid its end is received in this work on the basis of model which considers a plastic condition in final area of a crack. Pressure near to a crack are found. It is shown that in that specific case when extent plastic zone is equal to zero, the parity coincides with known criterion which is used at modeling of process of distribution of a crack in a rock mass. The forecast of values of length of a crack is received by means of spatial computer model. Numerical researches show influences on length of a crack of depth, lateral, breeds, extent of a plastic zone
