Alternating rock breaking test system based on laser melting-supercooled liquid jet

Abstract

The invention provides an alternating rock breaking test system based on laser melting-supercooled liquid jet, the test system is used for carrying out a high-low temperature alternating damage test on a rock sample, the test system comprises a box body, an instrument mounting table, a temperature monitoring device and an image monitoring device, and the rock sample used for carrying out alternating damage is arranged at the bottom in the box body; a laser and a nozzle are arranged on the instrument mounting table, the laser and the nozzle can move in the length direction of the cross beam structure, and the two ends of the instrument mounting table are correspondingly arranged on a pair of opposite side walls in the box body; the temperature monitoring device is used for detecting the temperature of the rock sample in the box body; the image monitoring device is used for acquiring an image of the rock sample; wherein when the rock sample needs to be subjected to high and low temperature alternating damage, switches of the laser device and the nozzle are turned on, the laser device emits laser, the nozzle sprays out supercooled liquid, the rock sample is subjected to alternating damage, and after the temperature of the rock sample is recorded, an image of the damaged rock sample is obtained.

Description

technical field [0001] The invention belongs to the technical field of rock mass structure testing, in particular to an alternating rock breaking test system based on laser melting-supercooled liquid jet. Background technique [0002] With the continuous development of my country's urbanization process, water conservancy, transportation, subway and other tunnel construction projects are also accelerating development. From the traditional rock breaking method of drilling and blasting to today's mechanical rock breaking, to the gradual and widespread application of jets such as lasers and liquid nitrogen in the field of rock breaking, there are various methods and forms of rock breaking, and they are constantly developing. However, in the process of rock breaking, the geological conditions are complex and changeable, and the different structures of the rock mass lead to the inability to further increase the rock breaking rate, and the degree of difficulty in rock breaking cont...

AI Technical Summary

Problems solved by technology

[0003] That is to say, for the rock-breaking process in the early stage of oil development and exploration drilling, there are technical disadvantages that the geological conditions are complex and changeable, and the rock-breaking rate cannot be further improved due to the different structures of the rock mass, and the difficulty of rock-breaking is constantly increasing;
