Cross-stepped type slope surface treatment method for mine dump
The invention discloses a cross-stepped type slope surface treatment method for a mine dump. The method comprises the following steps that a slope surface A of the mine dump is trimmed to make the overall slope gradient less than 50 degrees; a staggered stepped structure is arranged on the slope surface A of the mine dump, specifically, at least two groups of multiple rows of arc-shaped steps withthe middles arched upwards are dug from the slope top to the slope bottom in sequence, and one ends of the two groups of multiple rows of arc-shaped steps are arranged in a one-to-one correspondenceand mutually-staggered mode; maize straw or reed straw subjected to soaking and rolling is laid on the bottoms of arc-shaped containing grooves to form straw layers; cultivation sheet bodies are sequentially laid from arc-shaped steps N close to the slope bottom to arc-shaped steps I of the slope top; and shrubs are transplanted on the table boards at the two ends of a plurality of arc-shaped containing grooves. According to the method, vegetation coverage of the mine dump can be quickly recovered, water and soil can be effectively kept, natural disasters can be avoided, and certain washing treatment can be carried out on heavy metal-polluted soil.
本发明公开了一种矿山排土场交叉阶梯式的坡面处理方法，包括以下步骤：修整矿山排土场的坡面A至总体坡度小于50度；在矿山排土场的坡面A上设置交错式阶梯结构，具体为自坡顶至坡底依次挖设中部向上拱起的至少两组多排弧形台阶，两组多排弧形台阶的一端一一对应相互交错设置；将浸泡并碾压处理后的玉米秸秆或芦苇秸秆铺设在弧形容纳槽的底部形成秸秆层；自靠近坡底的弧形台阶N向坡顶的弧形台阶Ⅰ依次铺设培植片体；在多个弧形容纳槽两端的台面上移栽灌木。本发明方法，可快速恢复矿山排土场的植被覆盖并有效保持水土，避免自然灾害的发生，且能够对重金属污染的土壤进行一定的淋洗处理。
