“Flying pipe” and handling and operation of “gas-filled tube” are potential security issues, which bring difficult problems of blasting security management to public security organs.In order to solve these problems, a method of combining the optimized design of cracking pipe structure with the field explosion test was adopted.As a result, after "design-test-improvement" repeated research, a new type of fracturing pipe, a technology of inflation process in hole and a terminal management and control information system were successfully developed.According to the preliminary application study, the vibration value produced by carbon dioxide expansion blasting is only 1/20~1/15 of that produced by the same explosive blasting.
