Method for applying coal gangue to ecological restoration of mining area
The invention discloses a method for applying coal gangue to ecological restoration of a mining area in the field of ecological restoration of the mining area, the coal gangue has a rich pore structure, after the coal gangue is prepared into an ecological restoration material for a coal mining area, the content of kaolinite in the coal mining area is increased, and aluminum powder generates bubbles in the preparation process of the material, so that the coal mining area is effectively restored. The kaolinite-coal gangue composite material has the advantages that the kaolinite-coal gangue composite material is rich in internal pore structure, semi-open pores, closed pores and communicated pores in particles and gaps formed by natural accumulation among the particles of the material all improve the water retention capacity of the material and reduce the loss rate of the material, and meanwhile, the kaolinite content in the material is increased compared with that of the coal gangue, so that the water retention capacity of the material is also improved; in addition, an aggregate structure formed by aggregation of soil particles is compact, the water flow passing resistance is increased, the water retention capacity of the soil is reduced, the structure of the particles of the material is still loose after aggregation, and part of through holes are formed among the materials, so that the water and soil retention capacity of the material is further improved.
本发明公开了矿区生态修复领域的一种将煤矸石应用于矿区生态修复的方法，其中煤矸石本身有着丰富的孔隙结构，将煤矸石制备成煤炭开采矿区生态修复材料后，其内部的高岭石含量增多，且材料的制备过程中铝粉产生气泡，造成材料内部的孔隙结构丰富，其中颗粒内部的半开孔、封闭孔及连通孔，材料颗粒间自然堆积形成的缝隙，均提高了材料的保水能力，降低了其流失率，同时材料内的高岭石含量较煤矸石的含量有所增多，这也提高了材料的保水能力；此外土壤颗粒间的团聚形成的团聚体结构较为密实，加大了水流通过的阻力，降低了土壤对水的保持能力，而材料的颗粒经过团聚后结构依然疏松，且材料之间形成了部分的通孔，进一步提高了材料的水土保持能力。
