摘要

在保护物距离爆破源地较近，爆破防震要求高的环境下，辽宁有色地质局一O三地质队采取了分层爆破、逐孔起爆、反向起爆、控制最大药量、预裂减震沟、气泡帷幕等技术措施，成功地将抚顺大伙房水库输水（二期）取水头部围堰拆除，取得了较好的效果。%Because the protector is near the blasting source, and the blasting shockproof requirement is high, the Geological Team 103 adopted hierarchical blasting, hole by hole blasting, reverse initiation blasting, maximum dose control, pre-splitting damping groove, bubble curtain and other technical measures, and have successfully removed the cofferdam at Fushun Dahuofang reservoir delivery (Phase II) water intaking head and have obtained good effects.
