SUMMARY

The paper dIscusses the principle of using

method of multiple coverin'gs, called also the'

method of common reflection point, ta,king into account its ability of damping multiple !reflections.

Part I demonstrates that a possiobiUty exists at di'stLnguishizrg and dampi.ng multiple reflections if

the velocity of the propagation ' of sei.smic waves increaSf::s with depth, pro.vlded that the recording

!!I made with the a,id of sUlfficiently lo.ng geophone spaein!(. The efltectiveness of this method depends.

upon the time of reC<.lrcting of reflections and decreases with its increase.
