The cumulative proton production mechanisms are studied in neutrino-nuleus interactions, with the help of the propane-freon bubble chamber SCAT, irradiated to the neutrino beam at the Serpukhov accelerator. The kinematical correlations are observed between the cumulative proton and muon, as well as between a pair of final protons. These correlations can be attributed, respectively, to the two-nucleon correlation mechanism (TCM) and to the secondary pion absorption (SPA) mechanism. It is shown that the TCM contribution is more essential for peripherical interactions (about 50\%), while the SPA causes about a quarter of the inclusive cross section of the cumulative proton production.
