Good effect of cutting brittle materials such as concrete by premixed abrasive water jet shows that this clod cutting technology has a unique advantage in the schoolwork under urgent conditions.
The rock cutting techniques under deep water of practical application should consider the relations between cutting times, jet horizontally moving velocity and efficiency.
在深水环境条件下岩石切割技术的生产实际应用中，要综合考虑切割次数和射流横移速度与效率的关系；
