本发明公开了一种全风化层中污染物的固化方法。该方法首先向全风化层中注入粘土类物质，利用粘土类物质固化全分化层；再在固化网上平铺秸秆形成秸秆层，秸秆层上撒施固化剂；最后将处理后的固化网打入全风化层中，固化网中部分伸入全风化层内，部分外漏于全风化层外，在全风化层中形成阻隔层，实现全风化层中污染物的固化。同时，固化网、秸秆层和固化剂三者相互配合，形成三重防护，不但能固化和吸附废弃矿山内的污染物，还能吸附固化废弃矿山外进入矿山内的污染物。 The invention discloses a curing method for pollutants in a fully weathered layer. The method comprises the steps: firstly, injecting clay substances into the fully weathered layer, and curing the fully weathered layer by using the clay substances; spreading straws on a curing net to form a straw layer, and spreading a curing agent on the straw layer; and finally, driving the treated curing net into the fully weathered layer, specifically, part of the curing net stretches into the fully weathered layer, part of the curing net is exposed out of the fully weathered layer, a barrier layer is formed in the fully weathered layer, and the curing of the pollutants in the fully weathered layer is realized. Meanwhile, the curing net, the straw layer and the curing agent are mutually matched to formtriple
