摘要

为解决硐室爆破对软质岩体大边坡稳定性的影响

采用硐室拉槽

松动控制爆破

小硐室预裂

微差起爆技术等方案和分装药包法

试验研究了高30 m

长120余米的双边坡山体路堑一次性拉槽硐室爆破的技术问题.实验结果表明

分装药包法可以满足松动爆破技术要求

同时也可保证高沉积层状砂岩体大边坡的稳定性.

Abstract

For settlement of chamber blasting vibration on soft rock slope stability

chamber kerf blasting technique of a 30 m high and 120 m long road trench was experimentally studied with the separated charge method.It is showed that the separated charge method is satisfied with requirements of loose blasting technique and the stability of sandstone sedimentary deposit slope can be guaranteed.
