“下三带”理论对承压水上采煤底板突水的预测研究

Prediction of Down Three-zone Theory on the Floor Water Bursting in Mining on Confined Aquifer

对工作面采动过程中底板的破坏机理进行了阐释,并对"下三带"理论的概念及形成进行了论述,给出了相应计算公式,给出了煤矿底板突水预测防治的措施。

The paper explained the failure mechanism of floor caused by working face mining and argued the down three-zone and its formation. Corresponding calculation formulas and countermeasures for floor water bursting were given.
