The invention provides a gas phase change impact rock breaking model test system. The test system comprises a gas injection loading system, a reaction kettle, an impact release system, a data acquisition system and a sample and confining pressure loading system, the gas injection loading system is communicated with the pressure kettle through a first pipeline, and the gas injection loading system is used for providing gas with pressure for the pressure kettle; the pressure kettle is communicated with the impact releasing system through a second pipeline and is used for providing high-pressure gas for the impact releasing system, so that the impact releasing system completes impact operation on the sample; the sample is arranged in the confining pressure loading system; the data acquisition system comprises a plurality of pressure sensors, and the pressure sensors are arranged on the sample and used for monitoring a pressure time-history curve during gas impact rock breaking. The test system can be used for researching the influence on the carbon dioxide phase change impact rock breaking effect by controlling three variables including the initial pressure, the pressure during release and the flow in the pressure kettle.
Description
Technical field [0001] The present invention belongs to the field of gas-shaking model test technology, and specifically, a gas phase change rock model test system and method thereof use. Background technique [0002] In the prior art, most of the projects need to use explosives to blast, but explosive blasting technology does not meet most of the project environmental protection demand. As a new blasting technology, carbon dioxide phase transition is well applied to mine mining and basic excavation. This technology has a safe, low cost, simple construction operation, recyclable and non-polluting. Advantages; this technology can be widely used in roadbed excavation, coal mining, mining, clear blocking, building demolition and other engineering. [0003] At present, this technology is widely used in the actual engineering, but for this technology, there is still insufficient in indoor trial, especially in the initial pressure of airflow, phase change pressure, and sample intensity...
