Mine pit hole repairing method combining mine waste backfilling and residual sludge packaging
The invention provides a mine pit hole repairing method combining mine waste backfilling and residual sludge packaging. The mine pit hole repairing method comprises the following steps that fly ash-lime stabilized excess sludge is flatly laid to a natural base layer at the bottom of a mine pit hole and stacked to the side wall of the mine pit hole, and a bottom sludge lining layer and a side wall sludge lining layer are formed through compaction; the residual sludge, the anaerobic ammonia oxidation sludge and the nitrification sludge are sequentially backfilled on the bottom sludge lining layer to form a triple combined sludge layer; and backfilling mine wastes on the triple composite sludge layer to form a mine waste layer. In addition, the mine pit hole repairing method further comprises the step that after mine waste is backfilled, a top cover layer is laid on the mine waste. According to the method, the mine pit is backfilled with the mine waste and encapsulated with the solid waste such as the excess sludge, waste can be effectively treated with waste, the problems of geological environment disasters in mining areas, ecological restoration, vegetation restoration and the like are solved, and green mine construction can be promoted.
本发明提供了一种矿山废弃物回填联合剩余污泥包封的矿山坑洞修复方法。所述矿山坑洞修复方法包括以下步骤：将粉煤灰‑石灰稳定剩余污泥平铺至矿山坑洞底部的天然基础层以及堆填至矿山坑洞的侧壁，经压实分别形成底部污泥衬层及侧壁污泥衬层；将剩余污泥、厌氧氨氧化污泥和硝化污泥依次回填于底部污泥衬层上形成三重复合污泥层；将矿山废弃物回填于三重复合污泥层上形成矿山废弃物层。此外，所述矿山坑洞修复方法还包括矿山废弃物回填完毕后在其上铺设顶部盖层。本发明在矿山坑洞中回填矿山废弃物并采用剩余污泥等固体废弃物进行包封，可以有效实现以废治废，解决矿区地质环境灾害以及生态修复与植被恢复等问题，有助于推进绿色矿山建设。
