长沙矿冶研究院,爆破科研人员于1986年元月成功地利用控制爆破方法拆除了湘潭某厂一座废石灰立窑。该立窑外形如同圆形烟囱,但其高度与直径的比值相对较小,厚度较大,重心较低、稳定性较好。因而用控制爆破方法使其一次倾倒在技术上有一定难度。 Changsha Mining and Metallurgical Research Institute, blasting researchers in January 1986 the successful use of controlled blasting demolition of a factory in Xiangtan waste lime shaft kiln. The shape of the shaft kiln like a circular chimney, but the height to diameter ratio is relatively small, thicker, lower center of gravity, better stability. Therefore, using a controlled blasting method to dump it once in a certain degree of technical difficulty.
