摘　　要：某废弃矿山治理项目周围环境较为复杂,为获得适用于该矿区的岩体质点振动衰减规律即k和α值,采用TC-4850爆破振动测量仪,按照以爆源为起点呈射线状排设为布点原则,对现场深孔台阶爆破产生的地震效应进行监测。通过对测试数据进行曲线拟合,计算得出矿区爆破振动速度预测公式,并进行了频率分析及可靠性论证。The environment of an abandoned mine project is more complicated. To obtain blasting vibration attenuation law and the value of K and α applicable in the mining area, the monitoring of blasting seismic effect on deep hole bench blasting was carried out, with the TC-4850 blasting vibration measuring instrument, and in accordance with the principle of explosion source as a starting point and other holes being set by radial row for the distribution. Through the curve fitting of the test data, the formula for predicting the blasting vibration velocity was calculated, and the frequency analysis and reliability analysis were carried out.

关 键 词：爆破振动 曲线拟合 衰减规律
