爆破所引起的土壤质点振动,是造成爆区附近居民住宅和工业建筑的结构强度破坏的重要原因。因此在爆破设计时,正确合理地确定爆破震动的安全范围,不但可以保证矿区附近建筑物和结构物的安全,而且还能避免由于盲目拆迁建筑物而造成的经济损失。此外正确地确定最大允许装药量,可以大大地提高爆破作业的技术经济指标和不断地挖掘矿山的生产潜力。本文企图根据地震波的传播规律,提出爆
The vibration of soil particles caused by blasting is an important reason for the structural strength destruction of residential buildings and industrial buildings near the blasting area. Therefore, in the design of blasting, the safe range of blasting vibration can be correctly and reasonably determined, which not only can ensure the safety of buildings and structures in the vicinity of the mining area, but also can avoid the economic loss caused by the blind demolition of buildings. In addition to correctly determine the maximum allowable charge, can greatly improve the technical and economic indicators of blasting operations and continue to tap the production potential of mines. This paper tries to put forward the blast according to the propagation law of seismic wave
