Abstract: The search for high energy gamma-ray bursts and high energy radiation (Eγ ≥ 10 GeV) in correlation with the gamma-ray bursts registered at low energies (BATSE Eγ = 30 - 500 keV) has been carried out at the "Andyrchy" array of the Baksan Neutrino Observatory, INR RAS. Using "Andyrchy" data collected during 1996- 2001 years we have obtained a limit on the rate of gamma bursts with Δt = (1 − 50) second duration and corresponding energy fluences Wt) ≥ 5.6 × 10−3 × √(Δt) erg/cm2 in the declination band 10° ≤ δ ≤ 70°: Ωlim = 2.0 × 10−8 sec−1 at 90% c.l. 147 events have come into the field of view of the "Andyrchy" array during the period of 1996-2000 years (θ ≤ 50°). Range of limits on the energy fluence carried away by high energy gammas in the bursts is Wmax = 6.5 × 10−4 − 0.15 erg/cm2.
