Ecological restoration method for waste rock discharge field
The invention provides an ecological restoration method for a waste rock discharge field. The ecological restoration method comprises the steps that S1, an impermeable layer is laid at the bottom of the waste rock discharge field; s2, coal gangue is laid on the upper surface of the impermeable layer, and a pre-grouting layer is formed; then the pre-grouting layer is filled with a slurry material, and a composite filling layer is formed after cross-linking solidification; s3, a compaction layer is laid on the upper surface of the composite filling layer; and S4, a soil layer is laid on the upper surface of the compaction layer, and green plants are planted on the upper surface of the soil layer. The filling slurry material which is excellent in water retention performance, stable in performance and good in permeability to the coal gangue layer is provided, the filling slurry material is effectively poured into gaps of the coal gangue, effective coating and cross-linking solidification are conducted on the coal gangue, and the purposes of preventing spontaneous combustion of the coal gangue and preventing heavy metal seepage are achieved; and the anti-seepage effect on heavy metal ions is improved, so that the use requirements of a waste rock discharge field can be well met.
本发明提供了一种排矸场的生态修复方法，包括：步骤S1，在排矸场的底部铺设防渗层；步骤S2，在防渗层的上表面铺设煤矸石，形成预注浆层；然后向预注浆层中充填浆体材料，经过交联固化后形成复合充填层；步骤S3，在复合充填层的上表面铺设压实层；步骤S4，在压实层的上表面铺设土壤层，并在土壤层的上表面种植绿植。本发明通过提供具备优异保水性能、性能稳定且对煤矸石层具有很好的渗透性的充填浆体材料，将其有效地灌注进煤矸石的缝隙中，对煤矸石进行有效的包覆和交联固化，达到防止煤矸石自燃和防止重金属渗出的目的，提升了对重金属离子的防渗效果，从而能够很好地满足排矸场的使用需求。
