巷式开采和充填对隔离煤柱应力影响的实测研究

Measuring Research on Effect of the Tunnel Mining and Backfilling on Stress of the Coal Curtain

通过对邢东矿矸石充填巷式开采隔离煤柱的应力观测,得出了巷式开采和充填对隔离煤柱应力影响的初步规律,为认识巷式开采对煤柱附加应力的影响和充填体对煤柱的侧限作用提供了实测资料,也为将来观测设计提供了参考。

In the paper,a preliminary law that the tunnel mining and backfilling affect the stress on the coal curtain is revealed based on observation of the stress in coal curtain mining with coal refuse backfilling at Xingdong coalmine,which provides not only actually-measured information for understanding influence of the tunnel mining on the additional stress of the pillars and effect of the backfilling materials on confined effect of the pillars,but also references for observation design in the future.
