图们市月晴护岸工程块石料场洞室爆破设计简介

本文把洞室爆破施工技术运用于实际工程案例中,对设计洞室开挖部位进行山体原地面线测量,然后根据地形情况及各药室最小抵抗线、地面天然坡脚决定各药室装药量及洞身长度,并计算爆破漏斗半径,最后补测爆破影响线以外地形断面,以保证爆破工作安全实施。

The introduction for the design of cavity blowing up of the block rock material site in Yueqing bank protection of Tumen City

This paper introduces the design which puts the cavity blowing up construction technique into the practice projects,the original ground of the excavating part in the hill is measured,according to terrain circs and the least resisting line of each powder chamber,the chamber capacity to load the powder and the length of the cavity are decided by the savageness slope angle on the ground,the radius of blowing up funnel is calculated,the outside profiles of blowing up impact line is measured in the end to assure the blow up task to be constructed safely.
