危险烟囱的抢险爆破

对爆而不倒的危险烟囱进行快速、安全的爆破排除。在缺少原始结构资料和进行详细现场勘查困难的情况下,通过目测并根据以往工程经验和相关理论,决定对危险烟囱实施裸露贴敷药包定向控制爆破拆除。本工程确定了合理的爆破参数,核算了裸露药包爆炸空气冲击波超压对人员的损害和一次安全齐发药量,并采取了相应的防护措施。

EMERGENCY DEALING BLASTING OF DANGER CHIMNEY

The paper introduced a case of quick action blasting to eliminate the danger resulted from an uncollapsed chimney in blasting demolition. Being lack of original information of the chimney structure and difficulty in making a detailed site survey,bare-stick directional controlled blasting was determined to demolish the dangerous chimney based on experience and related theories. In the blasting, the reasonable blasting parameters were determined, the damage to person caused by superpressure of explode shock wave and once safety volley charge quantity were evaluated and checked, and the relevant defending measures were taken.
