Two-neutrino double beta decay can create an irremovable background even in high energy resolution detectors searching for neutrinoless double beta decay due to random coincidence of 2 nu 2 beta events in the case of poor time resolution. Some possibilities for suppressing this background in cryogenic scintillating bolometers are discussed. It is shown that the present bolometric detector technologies enable one to control this form of background at the level required to explore the inverted hierarchy of the neutrino mass pattern, including the case of bolometers searching for the neutrinoless double beta decay of Mo-100, which is characterized by a relatively short two-neutrino double beta decay half-life.
