The invention relates to a deep falling prevention method for a submersible. The deep falling prevention method provided by the invention is mainly used for solving the problem that the submersible is subjected to deep falling due to displacement cliff encountering during navigation. According to the method, impellers which are directly driven by direct-current motors are mounted at symmetric two sides of a shell of the submersible of a bow section, symmetric two sides of a shell of the submersible of a midship section, symmetric two sides of a shell of the submersible of a stern section, the middle point of a horizontal axis and appropriate positions, which are located below the horizontal axis and form included angles, of which each is 25-50 degrees, with the horizontal axis, each impeller is controlled by a deep falling control processor, an alarm is given when preset alarm is triggered, the impellers are started up when preset processing is triggered, the size of an impelling force of each impeller is adjusted and controlled so as to maintain the depth and balance for the submersible, the impellers stop working until operating personnel complete processing, and a controller returns to a standby state. The method is applicable to various submersibles.
