摘要
针对桃山矿充填开采过程中出现的堵管以及料浆流入后工作面的离析分层现象,基于固液两相流的基本理论,试验了一种新的管道输送充填料浆的方法——自流+泵送,并利用ANSYS模拟了不同条件下的管路全程压力分布,确立了相应地充填料浆浓度、输送流速。
Aiming at the phenomenon of plugging appeared in the process of mining and filling blocking pipe and slurry flows into the segregation layer in the aftermath of the filling,based on the basic theory of solid-liquid two-phase flow,tested a new method of pipeline transportation of the filling pulp-their ＋ pumping,and by using ANSYS to simulate the slurry concentration,conveying velocity,pipe diameter,and bend radius un-der the condition of four line to the pressure distribution,based on the analysis,established the corresponding concentration,filling pulp conve-ying velocity.
