摘要：针对不连沟煤矿F6204巷道底板滞后性阶段涌水现象，分析了涌水水量、水质随时间的变化特征，探测底板采动破坏深度，揭示了底板涌水通道的形成机制。研究结果表明；底板涌水量随时间延长呈现出由渗水一涌水激增一涌水衰减的渐变过程，涌水水质随时间延长由砂岩水向砂岩一老空混合水变化；涌水通道由F6203工作面、F6204巷道底板扰动形成的垂向通道和砂岩孔一裂陳含水层水平通道构成；初期砂岩含水层原始裂隙水对老空水涌出的封堵作用造成底板涌水滞后性、阶段性是由于含水层分布的空间位置所致，首先涌出砂岩裂陳水，其后为老空水及部分砂岩孔水，老空水水量、水压变化是造成涌水变化特征的主要原因。

Abstract: Aiming at the phenomenon of the delayed waler inrush from the floor of F6204 roadway , change characteristics of water discharge and quality with time were analyzed, the floor failure depth caused by mining was detected and the formatior mechanism of floor water inrush channel was revealed. The study results showed that the floor water inrush presented a gradual process of water seepage sharp increase of water inrush weakening of water inrush with the time extension, the waler quality changed from the sandstone water to sandstone gob mixing water with the time extension; the water inrush channels were composed of the vertical channels formed by the floor disturbance of F6203 working face and F6204 roadway and the horizontal channels in the sandstone porefissure aquifer; the delayed and phased water inrush led by the blocking effect of the original
fissure water in the sandstone aquifer on the water inrush

in the gob were caused by the space location of the aquifer distribution, the sandstone fissure water was discharged first, then the gob water and partial sandstone pore water, the change of the gob water quantity and pressure was the main reason of the water inrush change.
