水采浓煤浆床层过滤方式及机理的试验研究

Experimental study on technique and mechanism of bed filtration for recovery of dense coal slurry produced in hydraulic coal mine

细煤泥回收是水采矿井生产中不可缺少的一个重要环节 ,目前处理系统环节多、投资大、运行费用高 .简要介绍了在实验室模拟井下刮板脱水筛工作情况 ,采用床层过滤方式回收细煤泥 ,并对床层过滤机理。

Recovery of fine coal slime is an indispensable key process link in a hydromine. The processes in current use suffer from the drawbacks of being complicated in process links and high in initial and operating costs. A brief introduction is made of the laboratory drag flight dewatering screen operating under simulated underground condition for fine slime recovery by way of bed filtration. What follows then is a discussion of the operation mechanism and the relationship between the filtration parameters involved.
