摘　　要：某山坡露天石灰石矿的一侧为顺层岩质高边坡,其稳定性是矿山安全的主要问题,而影响边坡稳定的主要因素之一是爆破地震效应。通过该矿深孔爆破振动效应的试验和分析,获得了该矿不同岩性和岩层走向对爆破地震波传播的影响规律,为爆破地震预测和减震爆破设计提供了依据。The one side ot some hillside limestone quarry is high bedded rock slope, so the stability of this slope is a primary problem of mine safety, and the earthquake effect caused by blasting is one of great factors influencing slope stability. According to the testing and analysis of deep - hole blasting vibration effect at this mine, the influencing laws of different lithology and layer＇s strike on the spread of seismic wave caused by blasting were obtained, and a basis was given for forecasting earthquake caused by blasting and the blasting design of reduced vibration effect.
