摘要
在金属矿山中,利用全尾砂处理采空区越来越普遍,但由于尾砂的粒级过细,其本身的保水性好、渗透性差,若不采取措施,则充填体的质量会受到影响。通过渗流理论分析,充填体脱水部分为充填体内部的自由水,着重研究充填体内部脱水,以及如何提高充填体脱水速度。通过试验对比得出,从经济和效果方面考虑,选用渗透管进行脱水较为有利。
In metal mines, it is increasingly common to use unclassified tailings to treat goaf. But due to the small particle size of tailings, its own good water-retaining property and poor permeability, if measures are not taken, the quality of filling body can be affected. By percolation theoretical analysis, dehydration part is free water in filling body. The paper focuses on dehydration within the filling body and improving the dehydration speed of filling body. By contrast test, it is more advantageous to choose percolation pipe as the dehydration measure from the view of economy and effect.
