摘　　要：依据河流动力学理论及流体力学相关理论确定煤泥水沉降实验方法,并根据实验结果对煤泥水的沉降特性进行研究。通过对实验数据的分析得出,煤泥水的沉降过程可分为两个阶段:快速沉降阶段和缓慢沉降阶段,从入口处向水仓内,快速沉降阶段下降速率逐渐降低,缓慢沉降阶段速率则趋于相同。在井下水仓中,煤泥水快速沉降阶段与缓慢沉降阶段之间沉降速率存在明显拐点,而矿井水的沉降速率基本保持不变。It determined coal slurry sedimentation experiment method according to river dynamics theory and fluid mechanics theory, and it researched according to results of the experiments on coal slurry sedimentation characteristics. Through analysis on experimental data, we can obtain the settlement of coal slurry process can be divided into two stages：fast settling and slow subsidence stage,it fromed the entrance to the water tank, fast settling phase decreased rate decreases, slow subsidence rate tends to be the same. In mine water store- house,it exists obvious inflection point of coal slurry rapid subsidence and slow subsidence stage between sedimentation rate, and the coal mine water sedimentation rate remained basically unchanged.
