露天矿山深孔台阶爆破振动监测与分析

摘要

The fact that,the vibration of deep-hole bench blastin may affect the nearby house, led to the blasting vibration monitoring. Through a comprehensive analysis from the collected data,the relationship between attenuation law of bench blasting vibration velocity,coupling coefficient and the vibration velobity in the topographic and geologic conditions was obtained. In the similar topography and geological conditions,the results of monitoring and analysis to the deep-hole bench blasting are of some reference value.%针对露天采石场深孔台阶爆破振动可能对附近民房存在影响，进行了爆破振动监测．通过对采集的数据进行全面分析得出，该地形地质条件下，台阶爆破振动速度的衰减规律、不耦合系数与振动速度之间的关系．监测及分析结果对今后类似地形、地质条件下矿山深孔台阶爆破开采具有一定的参考意义．
