Hi
My Russian is not that good, so I will reply in English.
The kml model can export the entrances, if that is what you mean by "объектов". To get the name of the cave to display, you have to mark one or more stations as entrances. Something like this:
centerline
cs lat-long
fix 0 11:22:33.4 22:33:44.5 1234 # set the GPS coordinates and elevation of station 0
station 0 "Some cave name" entrance # Mark station 0 as an entrance and set the name to be displayed. Not necessarily the same station as the one with the coords.
