摘要
尾盐回填是老挝钾盐矿规模化开采利用的关键技术问题之一。本研究提出的"尾盐膏体胶结充填法",采用地面搅拌混合,尾盐膏体管道输送至井下采空区,回填膏体料在采空区胶结凝固形成充填体,其工程技术可靠性高,操作简便,易于接顶,是目前最佳的地下钾盐矿采空区充填方式。所采用的"氯化镁母液+凝结剂+氯化钠尾盐"回填配方还可用于采矿巷道隔离防护、溶腔修复等。
Tailings Backfill is one of the most important technical problem of the potash mine exploitation in Laos. This study proposes a 'pipeline pumping cement filling method' with high technical reliability and simple operation. It is by far the best underground potash mine filling method. 'Magnesium chloride liquor + coagulant + sodium tail' formula can be used to the mining tunnel spray protection,cavern filled in other areas and so on.
