针对煤炭开采易造成地表塌陷及含水层破坏等问题，采用类比法计算了彬长矿区规划新建的矿井——小庄矿井开采导水裂缝带高度，在此基础上分析了采煤对地下水的影响，并提出保水采煤的措施。经计算，采用分层开采时产生的导水裂隙带最大高度为147.84 m，在三盘区将导通安定组隔水层，造成宜君组、洛河组承压含水层破坏，导通区域面积为0.7736 km2。因此，在可能导通的区域应进行保水采煤以保证安定组隔水层的稳定，从而达到保护具有供水意义的含水层和保障矿井生产安全的双重目的。

Aiming at the problems such as collapse of ground surface and damage of aquifer induced by coal mining this paper calculates height of water flowing fractured zone in XiaoZhuang mine by using the analogy method. In addition, based on this, we analyzed the influence of mining and put forward water conservation while mining.Calculated from experimental data, height of water flowing fractured zones has an absolute maximum of 147.84 m by slice mining. Breakover of aquiclude of Anding Formation results in the destruction of confined aquifer of Luohe Formation in the third panel, the breakover area reached 0.7736 km2. Mining with water conservation should be applied in the area where the breakover may occur to ensure the stability of the aquiclude of Anding formation so as to achieve the double goals of protecting the water supplying aquifer and ensuring the safety of mine production.
