Abstract

A carbon dioxide explosion shock wave pressure testing device and a testing method thereof belong to the technical field of shock wave testing. Test device: including the base bracket and the test steel pipe, the limit collar is set on the base bracket, and the test steel pipe is fixed in the limit collar; there are plugs at both ends of the test steel pipe, and the plug is connected with the test steel pipe thread; Several threaded test holes are arranged on the top, and a threading hole is arranged on the plug at the end of the test steel pipe away from the test holes. Test method: Fix the test steel pipe on the base bracket, place the carbon dioxide cracker in the test steel pipe, block the two ends of the test steel pipe with plugs, and lead the detonation lead out from the threading hole; screw the shock wave into the test hole Pressure sensor; connect the shock wave pressure sensor to the data acquisition instrument through the signal amplifier through the data line, and then connect it to the computer, start the data acquisition, detonate the carbon dioxide cracker; perform data acquisition and storage, and the test is over.

Description

technical field [0001] The invention belongs to the technical field of shock wave testing, in particular to a carbon dioxide explosion shock wave pressure testing device and a testing method thereof. The invention can simulate on-site drilling in a laboratory to study the influence of various parameters on the shock wave pressure of carbon dioxide blasting. Background technique [0002] Carbon dioxide blasting is a new type of blasting technology used in coal mining. The carbon dioxide cracker is different from the traditional gunpowder blasting equipment. It is composed of a high-strength reusable metal tube filled with liquid carbon dioxide, a heater and a constant pressure energy release mechanism. Put the carbon dioxide cracker in the coal borehole, use the detonator to start the heater, heat the liquid carbon dioxide inside to make it into a gas, and the pressure in the pipeline continues to increase to press the constant pressure energy release mechanism, so that the ...
