摘　　要：为解放水库下煤炭资源,通过导水裂隙带发育规律计算,分析了煤炭开采对水库的影响。结合煤层赋存特征,提出了近距离复合煤层部分矸石充填开采措施,并预测了设计的开采方式下的导水裂隙带高度,验证了煤水协调开采的可行性。In order to liberate coal under the reservoir, the influence of coal mining on reservoir are analyzed by the calculation of height of the water flowing fractured zone. According to the occurrencecharacteristics of coal seams, some measures of the composite close-seams mining and part of gangue back-filling are proposed. The water fractured zone height with the designed mining ways is calculated,and the feasibility of harmony mining on coal water is verified.
