采动对红层水涌入矿井的影响

根据实际观测资料,论述采动作用下红层水力特征变化及对矿井充水的影响。红层在采动作用下,纵向上迅速形成发育较高的采动裂隙,构成红层水迅速下泄的通道,随后在上覆岩层重力作用下裂隙又被压实,从而阻碍了红层水下泄;横向上红层受采动影响的范围较小。

THE EFFECT OF MINING DISTURBANCE ON WATER INFLOW FROM THE RED BEDS INTO COAL MINE

Based on the data of actual observations, the paper discussed the changes of hydraulic characteristics in the Red beds and the effect of mining disturbance on water inflow in coal mines. Under mining disturbance, fractures are rapidly developed vertically in the Red beds, forming passages for water to discharge into mines. Then, fractures Red beds are compacted due to the gravity of overlying strata, blocking water inflow from the Red beds to mines. Horizontally, mining disturbance produces a limited influence in the Red beds.
