摘要
In east China , a great amount of water-logged land is caused by coal mining subsidence,which results in arduous reclamation tasks. Taking Hanqiao Coal Mine in Xuzhou as an example, this paper introduces a new reclamation method suitable for suhsided land caused by coal mining with high phreatic level in east China. The new method consists of two respects: 1 ) engineering reclamation measure is a non-filled method which mainly applies dredging approach ; 2 ) biological reclamation measure is a high beneficial pattern, which mainly makes use of dikes and ponds. The new engincering and biological measures of reclamation have been used widespreadly in Xuzhou mining area. Considerable economic benefits and social and environmental effects have been obtained.
