摘　　要：介绍了运用定向倾倒控制爆破技术拆除1座48 m高砖烟囱的成功实践。根据现场实际,合理选择了爆破方案、爆破缺口形状与尺寸、爆破参数、爆破网路,预开定向窗与倒向窗。分析了一些爆破安全问题,提出了一些安全技术措施。爆破达到了预期效果。The successful experience of using explosive demolishing a forty eight meter high brick chimney with controlling dumping direction was introduced. Based on site condition, we chose reasonably the blasting scheme and parameters, such as blasting cut and its size, firing network, orientation window. Some safety measures were put forward based on blasting safety question. It achieves the desired result and provides a reference for similar projects.
