| 中文摘要: |
| 随着开采深度及开采强度的增加，贵州黔北金沙县新化矿区出现了工作面顶板突水现象，涌水一度严重影响了矿井安全生产。为研究长兴组岩溶地下水向矿井的充水特征，在收集矿区煤矿勘探期间及矿井生产期间的大量地质及水文地质资料基础上，利用物探、钻探技术及矿井涌水与大气降水的动态曲线，分析研究了长兴组灰岩的水文地质变化特征，以及采动破坏后大气降水通过长兴组灰岩补给矿井的充水峰值与大气降水峰值之间变化特征。 |

| With the increase of mining depth and mining intensity，the floor water inrush phenomenon happened in the Xinhua mining area of Jinsha County，northern GuizhouThe water influx has seriously affected the safety production of the mineIn order to study the water filling characteristics of karst groundwater in the Changxing formation，in this article，it studied a large amount of geological and hydrogeological data during the exploration and production periods of coal mines in the mining areaBy using geophysical exploration，drilling techniques，and dynamic curves of mine water inflow and atmospheric precipitation，the hydrogeological changes of the Changxing formation limestone were studied，as well as the variation characteristics between the peak water filling and atmospheric precipitation when atmospheric precipitation recharged the mine through the Changxing formation limestone after mining damage |
