摘  要:
采煤引起的土地不均匀沉陷是造成水土流失、环境污染和土地荒芜的主要原因,但在目前的复垦工作中,矿区覆土来源的缺乏严重影响着复垦的进度。本研究利用有机、无机废渣混配的一种新型复垦材料(基质)进行了试验分析。研究结果表明:粉煤灰和糠醛渣以4:1~9:1的质量比混配的新型基质适合苜蓿、黑麦草和其它类似植物正常生长的肥力标准,为沉陷地的修复提供了新的理论与途径,而且以废治废,大大降低了复垦成本。同时,对有效控制水土流失,扩大耕地面积,促进经济、社会及生态环境的持续健康发展具有重要作用。

摘  要:
The coal mine subsidence land is often the source of environmental pollution, soil erosion and land desertification. But the reclaiming work is confined by the soil deficiency. A new type of reclaiming medium which is mixed by organic and inorganic residue is studied. The results indicate that the new reclaiming medium is suitable for the fertilizer standard of clover and rye grass etc.; the appropriate proportion of fine coal ash and furfural residue is 4∶1~9∶1,cuts down the reclaiming expense; the study applies the new theory and measure for reclamation,controls the water and soil loss process,increases the farm land dimension and greatly promote the continuous and healthy development of economy,society and environment.
