Artificial retaining dam of coal mine underground reservoir
The invention provides a multi-layer artificial retaining dam with foundation slabs. The artificial retaining dam is located between coal pillar dam bodies and used for isolating an underground reservoir from a roadway, two ends of the artificial retaining dam penetrate into the coal pillar dam bodies, the artificial retaining dam comprises a plurality of dam body structure layers located between the coal pillar dam bodies, and a foundation plate is arranged at the bottom of the multi-layer dam body structure layer. According to the artificial retaining dam of the coal mine underground reservoir, the foundation plate is arranged on the lower portion of the dam body, the punching stress on a roadway bottom plate under the pressure of roadway surrounding rock on the dam body is reduced, stability of the dam body and the whole is improved, and safety is improved.
本发明提出了一种带基础板的多层人工挡水坝，所述的人工挡水坝位于煤柱坝体之间用于隔离地下水库和巷道，并且所述人工挡水坝的两端深入到所述的煤柱坝体中，其中，所述人工挡水坝包括位于所述煤柱坝体之间的多层坝体结构层，所述多层坝体结构层的底部设置有基础板。本发明的煤矿地下水库的人工挡水坝坝体下部带有基础板，减小了坝体受到巷道围岩压力下，对巷道底板的冲切应力，提高了坝体及整体的稳定性，提高了安全性。
