Cofferdam blasting demolition method based on combination of variable linear density charging and digital electronic detonator

The invention provides a cofferdam blasting demolition method based on combination of variable linear density charging and digital electronic detonators. According to the cofferdam blasting demolition method based on the combination of the variable linear density charging and the digital electronic detonators, blasting demolition is successfully carried out on the cofferdam by researching the surrounding environment of a blasting area and a blasting scheme and adopting a digital electronic detonator detonating network and variable linear density charging method, the expected effect can be achieved through the method, safety of permanent buildings is guaranteed, and reference significance is achieved for similar blasting engineering. 本发明提供了基于变线密度装药与数码电子雷管相结合的围堰爆破拆除方法，通过对爆破区域周边环境及爆破方案进行研究，采用数码电子雷管起爆网路与变线密度装药的方法，对围堰成功实施爆破拆除，本方法能够达到了预期效果，保证了永久建筑物的安全，对类似爆破工程具有借鉴意义。
