ABSTRACT
High-pressure gas blasting has unique advantages over the traditional explosives blasting technology, which is suitable for projects with complex working conditions and high requirements for blasting effects and impacts, and has broad application prospects. The application of the high-pressure gas blasting technology is currently focused on the use of carbon dioxide expansion to achieve the fracturing effect in coal mines, thereby improving mining efficiency and safety performance. While the application in other underground engineering construction, as well as more high-pressure gas blasting technologies, theoretical research is relatively lacking. The article combines the current development status and direction of high-pressure gas blasting at home and abroad, and provides an in-depth analysis of the application and research of this technology, aiming to provide a reference for the development and research of underground engineering projects in China.
