高速公路爆破中破碎块度控制的研究

Research on Rock Fragmentation Grain Controlling of the Blast in Expressway

从理论分析入手 ,结合工程实践 ,探讨了高速公路爆破中大块产生的原因 ,并提出了控制破碎块度的有效措施。

Causes of producing large size fragmental rock in expressway blast were discussed with both of theory analysis and engineering practice. Effective measures to control the fragmental grain were presented.
