摘要
为了解决施工中“飞管”问题和“充气管”搬运、操作的安全隐患及公安机关对二氧化碳膨胀爆破治安管理的难题,采取对致裂管结构的优化设计和现场实爆试验相结合的方法。经过“设计-试验-改进”的反复研究,成功地研究出一种新型致裂管和孔内充气工艺并开发了末端管控信息系统。初步现场应用研究认为二氧化碳膨胀爆破产生的振动值仅是同样药量的炸药爆破产生的振动值的1/20~1/15。
"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.
