摘　　要：利用定向爆破成功地拆除复杂环境中的一座小直径砖砌烟囱,倒塌方向上空间的宽度仅为烟囱直径的两倍。通过一系列技术措施,使烟囱精确地按设计的方向倾倒,倒塌方向两侧的建筑物没有受到任何损坏,爆破达到了预期目的。A small diameter brick chimney in complex surroundings was demolished directionally by using blasting technique, where the width of the directional demolishment space is just two times of the chimney diameter. After technique measures were taken, the chimney collapsed along the designed direction precisely and the buildings around the chimney were not damaged. The expected results are obtained.
