中文摘要：

利用煤矿井下采空区进行矿井水资源储存和循环利用的地下水库技术为西部缺水矿区的绿色开采提供了新的途径,但其推广应用仍需符合一定的适用条件。综合采用现场实测与理论分析,结合神东矿区煤矿地下水库工程实践,开展了基于导水裂隙带高度的地下水库适应性评价方法研究。结果表明：地下水库储水的高效循环使用是保证该技术成功应用的关键,必须满足“水源”、“库容”和“通道”三大条件。采动覆岩导水裂隙作为地下水库水源补给的重要通道,是影响地下水库适应性的核心因素。利用“基于关键层位置的导水裂隙带高度预计方法”,判别具体开采条件导水裂隙带发育高度,当导水裂隙沟通区域补给水源（含水层）时,地下水库具备适应性;否则,区域水源水体一般难以汇聚至井下采空区,从而地下水库中可供循环利用的水资源量将难以保证,地下水库保水方法一般不适用。研究结果得到了神东矿区地下水库工程的验证,并指导了李家壕煤矿地下水库适应性评价和地下水库建设选址。

英文摘要：

The underground reservoir technology using goaf area for water resources storage and recycling has provided a new way for green mining in western water-shortage mining areas in China. However, the application of this technolo- gy needs to satisfy three necessary conditions, which are adequate water resources, sufficient reservoir capacity and connected water supply channel respectively. Combined with the practice of underground reservoir in Shendong mining area, the adaptability evaluation method of groundwater reservoir based on the height of water conducted fissure zone is studied. The results show that the ＂channel＂ condition of the water flowing fractured zone connected with the water supply source is the key to the adaptability of the underground reservoir in the water supply and water storage capacity of sufficient conditions. Using a method for predicting the height of water flowing fractured zone based on the key layerto judge the specific mining conditions of water conducting fractured zone＇ s development height, the underground res- ervoir has the adaptability when the water supply source （aquifer） is connected, otherwise, it is difficult to converge water to the underground mined out area, so the amount of water resources that can be used in the underground reser- voir will be difficult to guarantee. The adaptability evaluation method of underground reservoir based on the height of water flowing fractured zone is verified by underground reservoir project in Shendong mining area and is used as the guidance of the Lijiahao Coal Mine adaptability evaluation of underground reservoir and construction site selection.
