Full-tailing mine underground filling method
The invention relates to a full-tailing mine underground filling method. The full-tailing mine underground filling method comprises the steps that cement, sulfide and water are added into full tailings, high-strength filling slurry, medium-strength filling slurry and non-cemented filling slurry are prepared respectively, and the bottom of a stope, the lower portions of all layers of the stope and the upper portions of all layers of the stope are filled respectively according to a pilaster type upward layered mining method; the sulfide is sodium hydrosulfide or sodium sulfide. The full-tailing mine underground filling method is simple and low in cost, and the defects that in the prior art, tailings need to be subjected to grading treatment, the loss of the tailings is high, the full tailings are low in condensation speed and even not condensed, the filling quality is poor, the filling cost is high, and the cement-sand ratio is high are overcome.
本发明为一种全尾矿井下充填方法。一种全尾矿井下充填方法，为：向全尾砂中加入水泥、硫化物和水，分别配制成高强度充填、中强度充填和非胶结充填的充填料浆，按照壁柱式上向分层采矿法，分别填充采场底部、采场各分层下部和采场各分层上部；所述的硫化物为硫氢化钠或硫化钠。本发明所述的一种全尾矿井下充填方法，方法简单，成本低，解决了现有技术中尾砂需分级处理，尾砂损耗高、全尾砂凝结速度慢甚至不凝结、充填质量差、充填成本高、灰砂比高等弊端。
