摘要
在矿山具有生产规模的爆破作业中，研究了在降低震动强度的同时提高振动频率的新技术．分区起爆方案可显著提高振动频率，依据是波谱的广谱性和波的干涉作用，关键技术是使不同位置炮孔爆破地震波到达某一测点时有一合适的时间差。由于振动频率提高，在相同震动强度下，减轻了房屋的摆动程度。
Abstract In the mine blasting operation,the new technique on reducing vibration intensity and raising vibration frequency is studied. The detonating scheme by dividing into area can raise vibration frequency through the broad spectrum of wave spectrum and the interferencing action. The key technique is that the blasting seismic waves of blasting holes in different position to arrive at a measurement point have a proper difference in time. Due to raising vibration frequency,the swing intensity of buildings is reduced in the case of same vibration intensity.
