【摘要】 矿山爆破过程处理不当会对爆破附近地面居民建筑产生影响,以某露天矿山采场2次爆破试验为依据,采用TC-4850爆破振动记录仪对采石场爆破地震效应进行检测,并运用数理统计的方法对测试数据进行分析处理拟合出该片区的场地系数K、衰减系数α,得出该露天矿山爆破震动速度传播规律,为该矿山爆破最大单段药量确定和爆破震动控制提供重要的参考依据。更多还原

【Abstract】 If the blasting process of mine couldn′ t be treated properly, it would influence ground constructions of residents nearby. On the basis of two experiment of surface mine stope blasting. Take the TC-4850 blasting vibration recorder to observe the blasting seismic effect of the ballast pit. And using the method of mathematical statistics to analyze the test data processing fitting out of the ground coefficient K, the attenuation coefficient of the film area. The result can provide an important basis for confirming a reasonable amount of explosive during production and control impact of blasting earthquake.更多还原
