113.什么叫爆破安全距离答:所谓爆破安全距离,是指爆破时由爆炸中心到能保证人身安全和建筑物、构筑物免遭破坏所需的最小距离。实际上爆破安全距离是指爆破时免遭冲击波危害、地震波破坏、飞石击伤和毒气危害的安全距离。爆破作业时,正确确定爆破安全距离,是防止有害效应扩大、防止事故造成损失的重要措施。如果安全距离不当,往往会造成重大事故。例如,西南某处大爆破时,没有认真考虑、计算地震波的安全距离,致使国家铁路
113. What is the blasting safety distance A: The so-called blasting safety distance refers to the blasting center from the explosion to ensure personal safety and buildings, structures from the destruction of the minimum distance required. In fact, the blasting safety distance refers to the safety distance during blasting from shock wave damage, seismic wave damage, flying stone injuries and poisonous gas hazards. Blasting operations, the correct determination of blasting safety distance is to prevent the harmful effects of expanding and preventing accidents caused by the loss of important measures. If the safety distance is inappropriate, it will often result in serious accidents. For example, some large-scale blasting in the southwest did not seriously consider and calculate the safe distance of seismic waves, resulting in that the national railway
