摘要(Abstract):
在露天土石方爆破开挖过程中,常常采用水平炮孔松动爆破。本文利用等效转换的方法对露天水平炮孔松动爆破进行分类和爆破参数设计,所介绍的爆破参数设计方法在工程实践中得到了验证。
The loose blasting of horizontal longhole is often used in the open miningThe equivalent conversion method is used in classification of the loose horizontal longhole blasting and in design of the blasting parameters in this paperThe design method of blasting parameters proposed in this paper is proved in specific engineering
