Basic ideas of muon tracker technique for the solution of primary cosmic ray (PCR) composition problem in the energy range 1017−1018 eV are presented. The approach uses MC simulation data made with CORSIKA6.990 for "Pamir-XXI" site conditions. Similar technology can certainly be developed for other observation levels and interaction models. One can probably extend it to much higher primary energies.
