Cutting and Demolishing of the Ball Mill Foundation at a Cement Plant Using Controlled Blasting

介绍了基础切割拆除爆破的实践和经验。同时成功地应用了非电毫秒导爆管雷管孔外多级接力扩大雷管起爆段数的方法。

The experience for cutting and demolishing of the ball mill foundation at a cement plant using controlled balsting is introduced. Also applied successfully is the method of millisecond multi relay ignition by the non electric detonator outside holes, in order to increase the relays of detonation in controlled blasting.
