某隧道光面爆破优化设计
一、工程概况、环境与技术要求
1.1设计依据
根据爆破安全规程（GB6722-2003）、简明爆破工程设计手册等要求，进行某隧道的爆破优化设计。 采用矿山法开挖，其断面形状设计如图所示，围岩坚固性系数为f=6~8，围岩密度为2.3 0t/m3，周围围岩稳定，无大量的地表水，地下涌水量也不是很大。炸药单耗为0.15~0.25kg/ m3（软岩取小值，硬岩取大值）。每次爆破长度约为2.0m。采用台阶开挖方式。本次爆破设计采用两次爆破即先进行上半圆的导坑爆破再进行下部的台阶爆破。
1.2技术要求
（1）破碎质量好，块度均匀，基本无大块； （2）爆破地震、噪声冲击波和飞石危害较小。
（3）经济效益好，使穿孔，爆破，装运，破碎等各种工序的综合成本最低。
1.3工程地质条件
