苏联计划在纳伦河上采用定向爆破方法修筑坎巴拉汀坝。全苏水工设计院中亚分院即将完成设计。27万吨炸药爆炸时产生的巨大力量将在几秒钟内把4.6亿立方米的土石料抛入河谷,筑起3公里长,250米高的大坝。由此而节省的工程费用将多达2亿卢布。为了研究这种方法的特点,曾在布尔雷奇雅河峡谷中进行一次小规模定向爆破筑坝试验,炸药用量为800吨,筑起的大坝高度为60米。 The Soviet Union plans to use directional blasting on the Narendam to build the Kebarlatting dam. Quan Su Hydraulic Design Institute Branch is about to complete the design of Central Asia. The enormous power generated by the explosion of 270,000 tons of explosives will throw 460 million cubic meters of earth and stone into the valley in a matter of seconds and build a dam of 3 kilometers in length and 250 meters in height. This will save up to 200 million rubles in construction costs. In order to study the characteristics of this method, a small-scale directional blasting dam test was carried out in the Borerechya Gorge at a dosage of 800 tons of explosives and a dam height of 60 meters.
