导流洞出口岩坎爆破拆除是乌江彭水电站截流的关键。岩坎爆破方量约1.2万m3,爆破区距离保护物最近距离不足30m,施工条件复杂。爆破采用了高单耗、低单响的设计思路。本次爆破总装药量达17.8t,最大单响药量148kg,平均单耗1.5kg/m3,成功地完成了爆破,达到预计的效果。 Blasting at the outlet of the diversion tunnel is the key to the closure of Wujiang Pengshui Hydropower Station. Rock blasting square about 12000 m3, blasting area from the protection of the nearest distance of less than 30m, the construction conditions are complex. Blasting a high consumption, low single ring design ideas. The blasting of the total charge of 17.8t, the largest single dose 148kg, the average unit consumption of 1.5kg / m3, successfully completed the blasting to achieve the desired results.
