摘　　要：介绍非电毫秒微差控制爆破技术在混凝土结构拆除中的应用。由于已浇筑的塔架基础混凝土结构体型小,拆除时若钻孔或爆破设计不当,易出现爆破震动裂缝、产生远距离飞石或单次无法剥除等现象。论述了非电毫秒微差控制爆破技术方案的设计原则、钻孔布置、相关参数的设计和爆破结果。非电毫秒微差控制爆破的成功应用,保证混凝土拆除工作安全快速有效进行。An introduction was made on the application of non-electric millisecond controlled blasting technology in concrete demolition. Because the tower foundation concrete body is small, improper drill hole or blasting design may lead to blasting vibration crack, long distance flying stone or failure of concrete removal at one time. The authors discuss the non-electric millisecond controlled blasting technical scheme in respects of design principles, boring arrangement, design of relevant parameters and results of blasting. Successful application of non-electric millisecond controlled blasting technology is able to guarantee safe, rapid and effective concrete demolition.
