梯段的下向垂直炮眼
- He scored 23 points in opener for Nuggets, but it could leave a hole on the bench.
作为替补球员的他在季后赛首场为掘金砍下23分。 - Due to complex surroundings the exta-deephole controlled blasting is required to strictly control the vibration velocity,flyrocks and collapse distance of muckpile,so it is difficult to design and implement the blasting.An extra-deep-hole controlled blasting technology is successfully put forward,and it surpasses the normal small hole and small bench controlled blasting.
宝泉电站路堑超深孔爆破,处于复杂环境中,对环保要求严格,对爆破震速、飞石、爆堆坍塌距离等控制严格,爆破设计与施工难度较大,成功地探索了超深孔爆破控制技术,突破了小孔径、小台阶控制爆破的常规。 - In blasting excavation of underground workshop for Lashiwa Hydropower Station,the deep-hole pre-splitting blasting and bench cut blasting ware in-situ tested.The optimal excavation scheme and blasting parameters were determined through spacing network parameters,charge structure and millisecond time.And shock absorption effect of pre-splitting fissure was quantitatively studied,testing results show that pre-splitting fissure reduces by 30%~50%.
在拉西瓦水电站地下厂房爆破开挖施工过程中,针对复杂地质条件,进行了深孔预裂爆破和梯段爆破的多方案现场试验,通过调整孔网参数、装药结构和微差时间,确定了优化的开挖方案和爆破参数,并对预裂缝的减震效果进行了定量研究,结果表明预裂缝可降低振速30%~50%。
