Full-tailing damming method of damming machine
The invention provides a full-tailing damming method of a damming machine, and relates to the technical field of mine tailing pond damming processes. The method comprises the following steps: digging a dam slope drainage ditch; a leakage-proof layer is laid, and a film bag is placed on the leakage-proof layer; a construction platform is built, an ore pulp conveyor and a damming machine are driven to the construction platform and communicated with a pulp discharge pipe, the ore pulp conveyor and the damming machine, and a wake flow pulp discharge pipe of the damming machine is communicated with a material injection opening of the film bag; the damming machine advances on the construction platform in the damming direction for damming, the dry ore sand is used for damming after the damming machine rotates, the high-water-content fine ore mortar is injected into the film bag from the injection port, and the damming machine retreats to the heightened construction platform after damming is conducted to the specified length; and after the first layer is built, a second layer of film bags are laid on the original film bags, and the steps are repeated till the pre-built dam body reaches the designed height. By the adoption of the method, local materials can be used, full tailing sand is reasonably used for damming, the damming efficiency is improved, the damming construction period is shortened, the damming cost is reduced, and meanwhile zero emission of tailing slurry is achieved.
本发明提出了一种筑坝机全尾矿筑坝方法,涉及矿山尾矿库筑坝工艺技术领域。其包括以下步骤:挖坝坡排水沟;铺设防漏层,防漏层上方放置膜袋;堆筑施工平台,将矿浆输送机和筑坝机开到施工平台上,连通排浆管、矿浆输送机和筑坝机,筑坝机的尾流排浆管连通膜袋的注料口;筑坝机在施工平台上沿筑坝方向前进筑坝,筑坝机旋流后干矿砂用于筑坝,高含水率细矿砂浆从注料口注入膜袋,筑坝至规定长度后筑坝机回退至已加高的施工平台;筑完一层后再在原膜袋上铺设第二层膜袋,重复步骤至预筑坝体达到设计高度。采用本发明,其能够实现就地取材,合理利用全尾矿砂筑坝,提高了筑坝的效率,减少了筑坝的工期,降低了筑坝的成本,同时尾矿浆零排放。
