摘要
依据爆破理论，设计了在巷道围岩中进行松动爆破的有关参数，并在现场进行了工业试验。通过声波测试，证明了松动爆破有调整围岩应力分布的作用，即不仅降低了围岩应力峰值，且使集中应力移向深部围岩。
According to the blasting theory,the author designed the parameters of standing shot of surroudling rock and made industrial experiment in cite.It is proved that standing shot can adujst the stress distribution of surrounding rock by acoustic detection.Not only can it reduce the peak stress of surrounding rock,but also make the concentration stress transfer to deep surround-ing rock.
