Using modern scenarios of evolution of massive stars we study the rate of coalescence of binary black holes and predict their detection rate at
the level of the initial laser gravitational wave interferometers. The most optimistic detection rate is found to be about 10-30 events per year at the noise level h_rms=10^(-21) near  the frequency 100 Hz.
