复杂环境下40m高砖烟囱定向爆破拆除

摘要

A 40m high rick chimney under complex environment of campus was successfully demolished by directional controlled blasting. According to the environment and surrounding buildings, through elaborate computation about blasting cut and blasting parameters, the triangle directional windows was opened, and matched with strict drilling construction and careful safety protective measures, the goal of chimney collapsing following the designed direction accurately was achieved, and the safety of nearby building, staff and other facilities were guaranteed.%采用定向爆破技术，成功拆除了校园内复杂环境下40m高厚壁砖结构烟囱。针对现场环境和周围建筑物情况，通过精心计算爆破切口和爆破参数，开设三角形定向窗，配以严格的钻爆施工和周密的安全防护措施，实现了烟囱按照设计方向准确倒塌、保证了附近建筑物、人员及其它设施的安全。
