Detecting the hydrological responses of overburden aquifers to mining disturbance is significant in groundwater resource protection and mining safety. Thus, an effective and economical method of tracking such responses is necessary. This paper uses time-series analysis and groundwater tidal-response analysis to identify and quantify the hydrological responses associated with longwall mining, including changes in water level, specific storage (S_s), and the barometric effect. Before mining disturbance, these factors remains stable; however, under mining disturbance, the water level declines by 2.5–40 m, S_s decreases by 1–2 orders of magnitude, and the barometric effect declines. One possibility is that the production of horizontal or vertical fractures by mining disturbance leads to hydrological responses in overburden aquifers. Another possible mechanism is the redistribution of particles in the aquifer by waves from mining-induced seismicity, which changes the water level, S_s, and barometric effect. After mining disturbance, the recoveries in water level, S_s, and the barometric effect are influenced by the degree of mining disturbance, water inflow, or runoff recharge. The effective identification and interpretation of hydrological responses to mining disturbance improve our understanding of the impact that mining has on aquifer systems.

检测覆盖层含水层对采矿扰动的水文响应对于地下水资源保护和采矿安全具有重要意义。因此，需要一种有效且经济的方法来跟踪此类响应。本文使用时间序列分析和地下水潮汐响应分析来识别和量化与长壁开采相关的水文响应，包括水位变化、比存储 (S _s ) 和气压效应。在采矿扰动之前，这些因素保持稳定；然而，在采矿干扰下，水位下降2.5-40 m，S _s下降 1-2 个数量级，气压效应下降。一种可能性是采矿扰动产生的水平或垂直裂缝导致上覆含水层中的水文响应。另一种可能的机制是由采矿引起的地震活动产生的波浪重新分布含水层中的颗粒，这会改变水位、S _s和气压效应。采矿扰动后，水位的恢复、S _s和气压效应受采矿扰动程度、进水量或径流补给的影响。对采矿干扰的水文响应的有效识别和解释提高了我们对采矿对含水层系统影响的理解。
