The method of economic evaluation for the coal mining was established to analyze land destruction. The opportunity cost method was used to quantitatively analyze and estimate the economic loss of the land destruction by coal mining. At the same time, the dump land reclamation of the Yuanbaoshan Open Pit was taken as an example to evaluate environmental and economical benefit with the method of economic evaluation for the coal mining areas land reclamation.展开更多

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.展开更多
