Abstract：Through the systematic study and analysis of technological parameters of carbon dioxide blasting device,the theoretical and experimental analysis is made on the selection of the best angle of rock breaking by gas blasting.By systematically analyzing the process parameters of the carbon dioxide blasting device,conducting conductivity tests on the carbon dioxide fracturing device,and optimizing the selection of the thickness of the energy release shear plate,the influence of different parameters on the fracturing effect was ex-plored,providing empirical support for the rational optimization of processes.Research has found that when the thickness of the shear piece is 5 mm,the release pressure can reach 220 MPa;When the spacing between carbon dioxide disruptor and pore wall is 5-15 mm,the pressure conversion rate varies in the range of 71.1%to 82.1%;In the case of closed pores,the burst pressure of the carbon dioxide fracturing device can be 54.0%higher than that in the unclosed pore state.Through this research,it is expected to provide new theoretical support and practical guidance for blasting technology in engineering field.
