摘要
充填体不产生大规模破坏是高阶段矿柱成功回采的关键。为了指导矿柱爆破设计、降低爆破对充填体的破坏效应 ,试验研究了充填体动静力学特性 ,分析了爆炸应力波在充填体界面的传播规律 ,计算了爆破动载下高阶段矿柱不同开采高度充填体动静应力。对爆破动载下充填体稳定性进行了系统研究。
It is a key for a high level pillar mining's success to prevent backfill from being destroyed. In order to guide blasting design and reduce the adverse effect of blasting on backfill, the dynamic and static characteristics of backfill are studied, the propagating laws of blasting waves are analyzed on the filling interface and the dynamic and static stresses of backfill are calculated at different mining heights of high-stope pillar. A systematical study is made of the stability of backfill in blasting.
