opening a remotely controllable discharge port (2-4) so that stemming falls into a piston area pipeline (3-5), and moving the stemming along the piston area pipeline (3-5) to the matchable discharge port (3-4) and a discharge pipe (3-3) matched with the matchable discharge port (3-4) through a piston (3-2) so as to fill the blasthole.
