The method is described for estimation of the parameters of primary particles of extensive air showers by a complex high mountain detector array, developed in the framework of PAMIR-XXI project. The results can be useful for other high altitude projects as well as for the method of EAS detection in general. We present particular configurations of optical and charged particles detectors, methods of data processing, the achievable accuracy of reconstruction of primary particle parameters, namely, energy, direction, and mass/type. The most part of the results relates to the optical detectors which are able to deal with the EAS from nuclei in the range of primary energies E_0 = 100 TeV–100 PeV and with the gamma-ray showers of energies E_gamma ≥ 30 TeV. Also considered are the options of the charged particle detector grids intended to estimate the direction and energy of the EAS in the range of E_0= 1 PeV – 1 EeV. The estimates of the accuracies should be considered as upper limits of real experimental accuracies.
