摘要(Abstract)：

阜新电厂爆破拆除部分有主厂房及厂房内部的各种设备基础。本文介绍了爆破施工过程中的重点和难点,变截面182根立柱的爆破参数、厂房爆破参数及结构复杂处的预拆除处理。本次爆破采用四通和雷管组合连接的多层立体非电复式爆破网路,确保了起爆的安全性和可靠性;采用外挂式防护防止飞石;大段别微差和开挖减震沟。这些措施使得在1·22t炸药的装药条件下,爆破震动得到了有效的控制,保证了爆破的倒塌方向。
Blasting demolition of Fuxin Power Plant included the demolition of some main factory buildings and various kinds of equipment foundations within the factory.The key and difficulty issues occurring in this blasting were introduced in the article,such as the parameters of 182 posts with varied section area,the parameters of blasting and the pretreatment employed in the construction of the complicated structure.The blasting was carried out with the multi-layer,dimensioned and non-electric network that was composed of four-channel detonators and other detonators,thus the security and reliability were guaranteed.Since the network was hanging outside,the flying stones were efficiently avoided.Heavy section with little difference and the excavation of the ditch effectively controlled the vibration during the blowing-up under the condition of 1.22t powder charge.The direction of the falling dismantlement was therefore ensured.
