| 摘 要： | 从861-1工作面地质及水文地质条件出发,通过导水裂隙带高度计算、水质化验确定该面生产的充水因素为来自上部松散层底部的四含水,并对四含的沉积特征,富水规律进行了评价。依据现场实测资料和工作面回采过程中水量变化及涌出形式分析,总结出该面的出水机理受富水性差异、构造影响、采动矿压和采煤进度控制,并针对性地提出了相应的防治水措施。

| Abstract: | Start from geological and hydrogeological conditions of No.861 -1 working face,through height counting of water flowing fractured zone and testing of water quality,determined that water yielding in working face come from4th aquifer in the bottom of upper unconsolidated formation;and the depositional features of4th aquifer and the law of water-rich have been evaluated.Ac-cording to analyses on surveying information and water discharge in coal mining process of working face,sum up that water yield-ing mechanism of working face are controlled by differences of water-richness,structural influence,mining-induced rock pressure and coal winning rate of progress,and submitted purposefully appropriate measures on prevention and cure of water. |

| Keywords: | evaluation of water-richness feature of water discharge analyse of mechanism sum up measures |
