Hi,
I am assuming that the database was shutdown cleanly , ie with shutdown normal/immediate before the accidental deletion took place.
If so, then all committed transactions are already in your datafiles and there is no problem at all.
just mount the database, and then open with resetlogs option, ie, alter database open resetlogs.
This will create a new set of redo log files, but all the archived log files(which i think are anyway lost) can never be used again.
Hope this helps
