Initial dam and damming method using cemented tailings
The invention discloses an initial dam and a damming method adopting cemented tailings. The damming method adopting the cemented tailings comprises the steps that S1, a gelling agent is added into the tailings to form the cemented tailings; s2, a plurality of first-stage sub-dams are built in the stockpiling yard, and a first-stage discharging area is defined by the multiple first-stage sub-dams; s3, the first-stage discharge area is filled with cemented tailings to form a first-stage stockpiling body; s4, a plurality of second-stage sub-dams are stacked on the first-stage stockpiling body, and a second-stage discharging area is defined by the multiple second-stage sub-dams; s5, the second-stage discharging area is filled with cemented tailings, so that a second-stage stockpiling body is formed; s4, S4 and S5 are repeated until the height of the N-stage sub-dam reaches the target stockpiling height of the initial dam, and the N-stage discharge area is filled with cemented tailings to form the initial dam. According to the damming method adopting the cemented tailings, the problem of stock yard planning in engineering can be solved, a large-scale damming stock yard does not need to be found on the periphery of a dam body, the storage capacity of a tailing pond can be greatly consumed, and the applicability is high.
本发明公开了一种初期坝和采用胶结尾矿的筑坝方法，所述采用胶结尾矿的筑坝方法包括：S1：在尾矿中加入胶凝剂以形成胶结尾矿；S2：在堆存场中堆筑多个一期子坝，多个一期子坝之间围成一期排放区；S3：在一期排放区内填充胶结尾矿，以形成一期堆存体；S4：在一期堆存体上堆筑多个二期子坝，多个二期子坝之间围成二期排放区；S5：在二期排放区内填充胶结尾矿，以形成二期堆存体；重复S4‑S5，直至N期子坝的高度达到初期坝的目标堆存高度，且在N期排放区内填充胶结尾矿，以形成初期坝。本发明的采用胶结尾矿的筑坝方法可以解决工程中料场规划难题，不需要在坝体周边寻找大规模筑坝料场，可以大幅消耗尾矿库的库容，适用性较强。
