The headwork of water diversion tunnel is protected by a concrete plug predetermined in the reservoir side. The angle of horn-shaped concrete plug is level. The asphalt felt and steel pipe set between the plug body and the rock to form a weak surface plates and linoleum. By adopting domestic waterproof emulsion explosive, electronic detonator, and a series of technology, such as, double network, millisecond delay detonator, peripheral hole no using pre-splitting blasting, rock ballast treatment without slag collecting pit or buffer pit, the plug blasting was very successful.
