(57) Abstract :
The present invention relates to a blasting apparatus and a blasting method tor removing or flattening a underwater base rock, and
more particularly, to an apparatus and a method of blasting a underwater base rock, whereby a hole for laying an explosive is formed
in a base rock, using a guide pipe in a barge and preventing any other materials from flowing into the hole for laying an explosive; and
whereby an explosive is accurately loaded into the hole for laying an explosive through the guide pipe, without a diver to dive under
water. The present invention is realized by comprising a boring guide unit which includes a guide pipe passing through earth and sand
and being set on a base rock, a length adjusting unit being connected to an upper end of the guide pipe, and a pressurizing unit being
connected to an upper end of the length adjusting unit so as to be exposed above the surface of water, irrespective of the depth of
water.
