公路边沟中通信光缆沟的爆破开挖

Blasting Excavation of Furrow for Sound Optical Cable in Highway Side Ditch

结合9km长公路边沟中通信光缆沟的爆破开挖实例，提出了适合本工程的市孔方法、药量计算公式用防护措施。对类似工程有参考价值。

Based on the examples of blasting excavation of the furrow for sound optical cablein 9 km highway side ditch, the authors put forward proposals and ideas about the determination of blasting parameters so as to offer references for similar engineering.
