Search for high energy gamma-ray bursts

We report results of the search for high energy GRBs and high energy radiation in correlation with GRBs. The search has been performed at "Andyrchy" EAS array, for this purpose the single particle counting rate of the array has been used. The data were collected during 1996 - 2006 years with a live time 2290 days. has been also performed. We considered 189 GRBs occurred in the field of view of "Andyrchy" array with a zenith angle 50 . Using epoch folding method around trigger time of bursts the upper limits on the fluence during the prompt emission were obtained.
