【摘要】 为了合理有效利用矿井水资源,采用水文与水文地质学和数值模拟方法,研究了阜新矿区矿井水量动态的影响因素与补给机理。研究表明:矿井水量动态变化与当地大气降水动态变化具有相关一致性,地下水向矿井的运动为似稳定状态。该矿区现役矿井年排水量一直高于当地大气降水量(蒸发后)和地下水综合补给量,与巨大降落漏斗影响范围、采动裂隙网络扩张范围等有利于增加接受降水和地下水补给能力的次生水文地质条件有关。矿井水强烈持续抽排,导致土壤趋于干化并产生相应的生态环境问题。当前矿井排水量为矿井水最大可利用量,等同于开采补给量;影响阜新煤矿区矿井涌水量动态的主要因素是大气降水量及其年际分布。更多还原

【Abstract】 In order to reasonably and effectively use mine water,the impact factors and replenishment mechanism of mine water fluctuation in Fuxin mining area are studied by the methods of hydrology,hydrogeology and numerical simulation.Results from river and water output gauging show that the variation of the water output in coal mine is positively correlated with the variation of local atmospheric precipitation,and the out-flowing of groundwater to coalmine is quasi-stable.Annual water output of the service coalmine is always larger than the atmospheric precipitation(after evaporation) plus the total replenishment of ground water.This is caused by the increase of the ability on receiving precipitation and ground water replenishment of the secondary hydrogeologic structures induced by the enlarging of the descending hopper and the mining networks.Continuous pump drainage of water in coal mine results in the desiccation of soil and therefore the related ecological problems.The current water-output of coal mine,which is also the maximum available water amount,equals the mining replenishment amount.The principal factors that affect the groundwater fluctuation at Fuxin coal mine area include the year-to-year atmospheric precipitation distribution.更多还原
