摘要(Abstract)：

为保证平洞取水口一次爆破成功通水,现将平洞内岩塞爆破改为取水口水下石方爆破。平洞取水口采用明挖爆破降低了安全风险,人员在洞外操作,可避免洞内出现突发安全事故造成不必要的人员伤亡。爆破前在竖井内注水且明显高于水库水位,产生水位差,因竖井内外存在水头压力更有利于石渣排出,爆破时石渣可以大部分落入水库死水位以下,保证取水成功率。爆破后石渣抛掷明显,平洞进水通畅,满足泵站取水要求。
In order to ensure the adit water intake water-passing successfully of one time blasting,underwater rock blasting of water intake is applied instead of rock plug blasting in the adit.The open excavation blasting can greatly reduce the safety risk,operating by people outside the hole can avoid the occurrence of sudden safety factors in the hole causing unnecessary casualties.Before blasting the water is injected into vertical shaft and the water level is significantly higher than the reservoir water level,making a water level difference.The water head pressure inside and outside the vertical shaft helps the discharge of rock ballast,most rock ballast can fall into the reservoir under the dead water level when blasting to ensure the success of water intake.After blasting rock ballast falls obviously and the water flow is smooth,which satisfy the water intake for the pumping station.
