摘要
根据爆破现场环境的情况 ,倒塌方向只允许向正北方向倾倒 ,只有利用烟道口部分作为爆破缺口一部分 ,才能保证烟囱定向准确 ,又能减少炮孔数量。为保证倒塌方向的准确和可靠倾倒 ,在爆破缺口左侧采取了预开天窗 ,在右侧炸断烟道口两侧混凝土立柱的方法 。
On the basis of the conditions in the blasting field, the collapse can only be allowed in one direction(north). The flue hole was utilized to ensure the accurate blasting direction and to decrease the number of holes. In the implementation, the methods of pre opening a skylight at the left side and breaking the concrete columns beside the flue hole were adopted to ensure the accurate and reliable blasting.
