Analysis of Influence Characteristics on Slope Stability of Underground Mining in Slope Outer Zone

Abstract:

Under the action of surface-underground unite mining, Slope stability is related to underground mining location and mining space dimension, This paper studies the underground mining of slope outer region on slope stability influence characteristic; With the increase of mining width stability coefficient increases, when mining width reach a certain value stability coefficient tends to constant; With the increase of mining depth stability coefficient increases, when mining depth reaching a certain value stability coefficient began to decrease; this show that the underground mining has a direct effect on slope stability, its size needs a combination of their relative spatial position relation and mining geometric size to determine.
