【摘要】 为确定某露天石材矿开采爆破震动的衰减规律及其对邻近村庄建(构)筑物的安全影响,对该矿某次开采爆破进行了震动测试。通过分析实测数据,找出了计算该矿开采爆破震动速度的参数,以及最大单响允许起爆药量;得出了在当前的开采爆破条件下,爆破引起的震动不会对邻近村庄建(构)筑物造成损坏,但要注意多次爆破的积累损伤效应等重结论;并提出了一些控制爆破地震效应的建议。更多还原

【Abstract】 In order to determine the decaying law of blasting vibration and its influence on the security of the building(construct) of the near village while mining stone in some quarry,the author tested the blasting vibration in once exploiting in the quarry.By analyzing the in situ measured data,and the suitable values of the parameters k and αused for calculating the vibration velocity induced by blasting was found out,and the most explosive quantity of single blasting for mining stone material in this quarry.A main conclusion was drawn that the blasting vibration cannot cause the damage on the building of the near village in current blasting operation,but the accumulated damage effect should deserve attention.some advices on controlling the blasting vibration is proposed in this paper.更多还原
