摘　　要：对于重心较低、环境相对复杂的的砖混结构烟囱进行拆除,采用定向倒塌爆破技术,通过精心设计爆破开口形状与位置、开口圆心角及弧长、开口高度、孔网参数和单孔药量等参数,合理布置中心定向窗和三角形定位窗,辅于严格的钻爆施工要求和周密的安全防护措施,定能在保障附近构造物及人员设施安全的情况下实现烟囱的准确倒塌。For a lower center of gravity, the environment is relatively complex of brick concrete structure chimney was removed, using directional collapsing blasting technology, the blasting through carefully designed shape and position, opening angle of center of circle and arc length, opening height, hole pattern parameters and single hole charge parameters, heart directional window and triangle location window reasonable arrangement, auxiliary in the strict drilling and blasting construction requirements and detailed measures of safety protection, can realize accurate collapsed chimney in the security structure and personnel facilities near the safety case.
