Method for activating dead soil layer of mine dumping site
The invention discloses a method for activating a dead soil layer of a mine dump, which comprises the following steps of: S1, performing soil layer parameter analysis on the mine dump, and determining the burial depth of the dead soil layer needing to be activated; s2, dividing the operation area into net-shaped grids; s3, drilling and digging glass liner-shaped soil holes in the net-shaped grids; s4, in the net-shaped grids, net-shaped grid micro-terrains are arranged around the soil holes; and S5, paving a biochar material on the net-shaped grid microtopography, and filling the soil holes with a humus material. According to the method, the mine dump is divided into the net-shaped grids, the concave catchment area can be formed, and rainwater can be fully utilized; and the net-shaped grids can avoid large-scale ploughing and soil layer reconstruction, and disturbance to surface soil and plants of the mine dumping site is reduced. Glass-liner-shaped soil holes are formed in the net-shaped grids, rainwater can be further gathered, and the rainwater moves towards the periphery through the soil holes to supplement water for plant root systems; the soil holes gradually collapse under the effect of soil collapsing, and the effect of local soil loosening is achieved.
本发明记载了一种活化矿山排土场死土层的方法，包括以下步骤：S1，对矿山排土场进行土层参数分析，确定需进行活化的死土层的埋深；S2，将作业区域划分为网状方格；S3，在网状方格处钻挖出瓶胆状土壤孔；S4，在网状方格中，围绕土壤孔设置网状方格微地形；S5，向网状方格微地形处铺设生物炭材料，向土壤孔内充填腐殖质材料。本方法通过将矿山排土场划分为网状方格，能够形成凹形汇水区，可以充分利用雨水；且网状方格能够避免大规模翻耕和土层重构，减少对矿山排土场表土和植物的扰动。网状方格里设置瓶胆状土壤孔，能够进一步的聚集雨水，雨水土壤孔内向四周运移，为植物根系补充水分；土壤孔在土壤湿陷作用下逐步坍塌，起到局部松土的作用。
