苏联科学院西比尔斯克分院液压动力及СКБ液压脉冲技术研究所研制成功,非爆破破坏坚硬材料的有效方法和工具.在六十年代初就已开始研究高速射流的可能性.为此,在研究所内完成了射流方面的大量理论和试验工作并创造了压力2000-10~5帕(1帕=(1/10~5)巴)的连续射流和压力70000-10~5帕[注]的脉冲射流试验装置.获得了效果良好的破坏指标。例如,在一块厚120毫米的天然黄铜块上一次射击就打透了一个孔眼,用这种射流还破坏了极硬岩石.其中该装置在波洛克露天矿的花岗岩和“十月革命五十周年”煤矿坑道中的试验表明,随着岩石强度增大,破坏能量急剧增长,并且证明在工业条件下,采用射流来破坏极硬岩石在经济上不合适。由该资料的分析表明了射流应用的有效范围,而且它不宜在中等强度以上的岩石中推广。
The Institute of Hydraulic Power and the СКБ Hydraulic Pulse Technology Institute at the Šibirsk branch of the Russian Academy of Sciences developed effective methods and tools for the successful destruction of hard materials other than blasting and started to study the possibility of high-velocity jets in the early 1960s. A great deal of theoretical and experimental work was done on the jet flow and a series of jets of pressures from 2000-10 to 5 bar (1 Pa = (1/10 ~ 5) bar) and pulsed jets of 70000-10 ~ 5 Pa [ Test device. Obtained a good indicator of damage. For example, a hole in a shot of 120 mm thick natural brass was punctured by a jet that also destroyed very hard rock, which was deposited in the granite of the Pollock open pit mine and the “ Anniversary ”tests in coal mine tunnels show that as rock strength increases, the destruction energy increases dramatically, and it is economically inappropriate to use jets to destroy very hard rocks under industrial conditions. The analysis of this data shows the effective range of jet applications, and it is not suitable for generalization in rocks of medium strength.
