摘要
本文根据稳定性动力准则，得到了采场巷道受静水压力作用下，发生冲击的临界峰值应力深度和发生冲击地压的临界开采深度，解释了冲击地压发生的一些现象，为现场确定冲击地压危险指标，提供了理论依据。
ased on the dynamic criterion of stability,the paper inferred,for the roadway under hydro-static pressure, the critical depth,L,of peakstress for rock burst and the critical depth,h,forthat;whereThereby, the paper explains some phenomena ofrork burst and provides the basis for mining engi-neers to determine the rock burst hazafdous in- dices.
