爆破引起的地震炸药爆轰产生的能量迅速传入地层,直接引起地层震动,而地层震动本身也表明对这些能量输入的反应。密闭炸药利于波峰更大、周期更长的脉冲出现,并且导致较高的峰值振速和较低频率反应。经验丰富的人常常认为,假如岩石没有得到有效破碎,则使地层震动的能量就会额外增多,这种观点在某种程度上是正确的。最易增大地层震动的方式之一是炮孔前部的抵抗线过大。因此, Blasting caused by explosives detonation seismic explosions generated energy quickly into the formation, directly caused by formation vibration, and formation vibration itself also shows the response to these energy inputs. Hermetic explosives facilitate the appearance of larger, longer-duration pulses and result in higher peak velocity and lower frequency response. Experienced people often think that if the rock is not effectively crushed, the energy that vibrates the formation increases an additional amount, a view that is somewhat correct. One of the easiest ways to increase formation vibration is to have the line of resistance at the front of the blasthole too large. therefore,
