Slope surface treatment method of mine waste dump
The invention discloses a slope surface treatment method of a mine waste dump. The slope surface treatment method comprises the following steps that a slope surface A of the mine waste dump is trimmeduntil the overall slope is less than 60 degrees; multiple rows of arc-shaped steps with middles upward arched are sequentially excavated in the slope surface A of the mine waste dump from the slope top to the slope bottom, and at least one arc-shaped accommodating groove is excavated in a table top of the uppermost arc-shaped step I close to the slope top in the length direction of the arc-shapedstep I; corn straw or reed straw after soaking and rolling is paved on the bottoms of the arc-shaped accommodating grooves to form straw layers; cultivating sheet bodies are sequentially paved from the arc-shaped step N close to the slope bottom to the arc-shaped step I at the slope top; and shrubs are transplanted on the table tops of the two ends of the multiple arc-shaped accommodating grooves. According to the slope surface treatment method, the vegetation coverage of the mine waste dump can be quickly restored, the water and soil are effectively conserved, the occurrence of natural disasters is avoided, and certain leaching treatment can be conducted on the heavy metal contaminated soil.
本发明公开了一种矿山排土场的坡面处理方法，包括以下步骤：修整矿山排土场的坡面A至总体坡度小于60度；在矿山排土场的坡面A上自坡顶至坡底依次挖设中部向上拱起的多排弧形台阶，且在靠近坡顶的最上方的弧形台阶Ⅰ的台面上，沿弧形台阶Ⅰ的长度方向上挖设至少一个弧形容纳槽；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。
