本文主要介绍高压水射流切割岩石的研究结果及对这些结果的说明。第一部分主要分析比较了“传统”切割的理论模型,第二部分叙述了试验装置;第三部分给出了高压水射流切割岩石的试验结果;第四部分介绍采用或不用化学添加剂切割岩石的对比试验和添加剂的作用及其经济效益。采用下列符号: P——在喷嘴上游测得的水射流压力, MPa; φ——喷嘴直径,mm; x——喷嘴与岩石问的距离,m;

This paper mainly introduces the research results of high pressure water jet cutting rock and the explanation of these results. The first part mainly analyzes and compares the theoretical model of “traditional” cutting, the second part describes the experimental device; the third part gives the test results of high pressure water jet cutting rock; the fourth part introduces the comparison of cutting rock with or without chemical additives The role of test and additives and their economic benefits. The following symbols are used: P - water jet pressure measured upstream of the nozzle, MPa; φ - nozzle diameter, in mm; x - distance between the nozzle and the rock, in m;
