中远区微差爆破振动叠加效应产生的主要因素是介质的衰减慢。 振动叠加强度与爆源结构特性、爆心距和间隔时间有关。
The intensity of vibration superposition is affected by the characteristics of explosion source , millisecond delay interval and distance between explosion source and measuring point.
确定合理的微差间隔时间，既是保证爆破质量的需要，又是达到爆破降震的关键。
To determine rational microsecond delay time is both the requirement of ensuring blasting quality and the key to achieve blasting vibration reduction.
根据生产实验结果提出了东鞍山矿微差爆破适宜间隔时间的数值。
The modelling experiment has shown that the procedures are practicable, the reasonable values of the time interval for long hole m…
