摘要: 干旱区草原露天煤矿排土场水土流失严重,导致周边土壤盐渍化和草场退化,是干旱区草原露天煤矿土地复垦的重点和难点。以内蒙古胜利东二号露天矿排土场为例,通过实地调研与资料分析,对矿区采取的复垦技术进行了分析和总结。结果表明:①干旱区草原露天矿土地复垦的限制性因素主要有表土不足、水资源短缺、适宜物种少3种。②矿区可采取的工程措施包括表土剥覆、草帘固土防沙,生物措施有施用有机肥及合理配置草、灌、乔比例。研究结果可作为同类型草原矿区土地复垦的技术参考。

Abstract: It is a substantial issue for land reclamation of surface coal mine in arid grassland that soil erosion of open pit coal mine leads to soil salinization and surrounding grassland degradation.Taking the dump of No.2 surface coal mine in Shenglidong mining area in Inner Mongolia as a case.The research method is the combination of on-site investigation and data analysis.The results indicate:①There are three typical limiting factors for land reclamation such as insufficient surface soil, water shortage and few suitable species in arid grassland.②Meanwhile, the corresponding engineering measures in Shenglidong mine include removing and covering topsoil, using mat to prevent soil erosion; biological measures involve the application of organic fertilizers and reasonable allocation of herbage, bush and arbor.The results can be technological reference for the similar land reclamation.
