Before the blasting preliminary set is the charge detonation critical diameter, which is taken to be equal at least to 0.5 of the hole diameter. Then, according to the empirical dependence, the relative density of the explosive charge is determined, corresponding to the mentioned critical diameter of charge detonation of the given explosive, and on the basis of the obtains data, variation of the explosive density is calculated according to the hole depth depending on the height of the water tamping column and the initial density of the explosive. At charging of the hole the emulsion explosive is sensitized by the mentioned of gas generation to a density, at which the explosive density lower than the critical density for the given diameter of the hole is maintained in the bottom part of the hole to be charges. 
     EFFECT: enhanced capacity of drilling and blasting operations due to the use of deep holes charged with the use of mechanized charging installations.

Abstract: FIELD: the inventions refer to the field of radio technique particularly to the mode and the arrangement of time-and-frequency synchronization of the liaison system. 
     SUBSTANCE: the evaluation of the temporary provision of the signal is executed in two stages. On the first stage a decisive function with a wide useful response is formed and that increases possibility of regular detection of the signal. On the second stage a decisive function with a narrow useful response is formed and that allows receive an exact evaluation of the temporary provision of the signal. The evaluation of the frequency shift is also formed in two stages. At that the quality of this evaluation is high because it is based on qualitative evaluation of the temporary provision of the signal. The other distinctive peculiarity of the invention is possibility of synchronization at relatively significant initial values of the frequency shift and that is unattainable to many known modes and arrangements of time-and-frequency synchronization. 
     EFFECT: increases noise immunity of time-and -frequency synchronization of the liaison system.
