远距离爆破震动监测(距药包距离大于10m)已经历了数十年的广泛研究,已建立的这种监测技术相当完善,并有大量的基本数据见诸于文献。爆炸产生的震动信号经岩体传播其频率和震幅均有衰减。远距离震动监测比近距离监测的频率较低且震幅较小。远距离震幅的推算,广泛采用药量换算定律。因此其监测系统设计和传感器的选用就显得很
Monitoring of long-range blasting vibrations (distances greater than 10 m from the kits) has undergone extensive research over the decades and the monitoring techniques that have been established are quite sophisticated and a large number of basic data are available in the literature. Vibration signals generated by the explosion spread through the rock mass frequency and amplitude attenuation. Long-range vibration monitoring than the close-range monitoring of low frequency and amplitude smaller. The calculation of long-range amplitude, widely used dose conversion law. Therefore, its monitoring system design and sensor selection is very significant
