borehole hydraulic mining

This paper presents the design principle of the experimental bench of the squirt gun used in borehole hydraulic mining.

介绍了钻孔水力采矿射流水枪试验台的设计原理 ,在该试验台上可以模拟水枪在大气中的自由射流、模拟无压流体淹没条件下的射流以及模拟有压流体淹没条件下的射流等。

Focusing on design of nozzle-the crucial element of boring hydraulic mining, the test data were analyzed and researched based on the experiments of small diameter nozzles.

围绕钻孔水力采矿的关键元素喷嘴,在进行小直径喷嘴试验的基础上,分析研究试验数据,提出喷嘴的设计思路,完成喷嘴的基本选型。
