COMPLEXITY STUDY OF REDESTROYED STRATA CAUSED
BY DEEP MINING IN RESOURCE DEPLETION AREA |

|
Abstract In the resource depletion area，there are many abandoned stopes and the strata have been destroyed many times after years of mining in top strata. The rules of further destruction caused by deep mining or simultaneous mining at the top and deep strata，and subsidence along depth direction and the accumulative effect of damage are analyzed. The complexity of strata redestruction and the mechanism of worsening of earthquake- resistant behavior in the resource depletion area are discussed，and evaluation methods and resuming measures of earthquake-resistant behavior are proposed.
