%X 岩溶水害一直威胁着我国煤炭安全开采。以安徽淮南顾北煤矿中央1煤采区下部灰岩为对象，在分析矿井水文地质条件的基础上，在2022年5月至6月间，开展了顾北煤矿中央1煤采区C3I组灰岩放水试验工作，通过地下水动态变化分析，不同含水层之间水力联系差异较大，结果表明：中央1煤采区C3I组灰岩含水层与新生界松散层之间无水力联系，接受C3II和C3III组浅部露头区补给，无奥灰水补给。南一、北一采区与中央1煤采区间不存在明显水力联系，为三个相对独立的水文地质单元。<br />
Karst water disaster has been threatening the safe mining of coal in China. Taking the limestone in the lower part of the central 1 coal mining area of Gubei Coal Mine in Huainan, Anhui Province as the object, based on the analysis of the hydrogeological conditions of the mine, from May to June 2022, the water discharge test of C3I group limestone in the central 1 coal mining area of Gubei Coal Mine was carried out. Through the analysis of groundwater dynamic changes, the hydraulic connection between different aquifers is quite different. The results show that there is no hydraulic connection between the C3I group limestone aquifer and the Cenozoic loose layer in the central 1 coal mining area, which is recharged by the shallow outcrop area of C3II and C3III groups, and there is no Ordovician limestone water recharge. There is no obvious hydraulic connection between the south and north mining areas and the central 1 coal mining area, which are three relatively independent hydrogeological units.
