| Abstract: | The present paper introduced a chimney demolition case conducted in a power plant in Shanxi Niangziguan.The chimney,standing at 100 meters-high and being in reinforced concrete structure,was erected in a very complicated environment which was so narrow that there was not much area for the collapse.And for this reason dedicated bursting program should be designed,including the selection of reverse trapezia blasting cut,the optimization of blasting parameters,square hole arrangement,the employment of relay penthouse cluster ignition network,and careful organization and construction plus effective protective measures.The blasting demolition of the chimney was very successful owing to the dedicated design. |
