摘要(Abstract)：

在城市内破损山体治理中,通过采用深孔控制爆破、毫秒延时起爆网路及合理的爆破参数,防止了爆破飞石、降低了爆破振动,保证了爆破效果。本工程成功地对残留巨石柱进行了一次性爆破,可供类似工程借鉴。
The paper described an ultra-deep hole controlled blasting used in removal of a huge stone column remanent in management of damaged mountain located in city.The blasting was ignited by using millisecond delay network and operated by employing rational blasting parameters.And as a result,the fly rock was prevented,the blasting vibration was reduced,and therefore,the good blasting effect was ensured.The blasting was successful in one single operation for the removal of the object and offered valuable reference to similar engineering.
