深凹露天爆破震动速度衰减规律实验研究
|
摘要
传统的萨夫斯基公式确定深凹露天爆破振动速度衰减规律时具有很大的误差。提出了一个考虑了药量、爆心距、高程效应、自由面等因素的修正公式模型。现场的实验表明;该修正公式比萨夫斯基公式更好的描述深凹露天爆破振动速度衰减规律;通过合理孔网参数优化也可降低爆破振动速度。
The traditional Savski formula determining blasting vibration velocity in deep open-pit mining results in large error.A modified formula considering some factors,such as charge volume,blast center distance,altitude effect,free surface,etc.was proposed.The field experiments show that the modified formula is much better than the Savski formula in describing attenuation law of blasting vibration velocity in deep open-pit;and the reasonable optimization of blasting parameters can also decrease the blasting vibration velocity.
