摘要
针对我国井工开采对土地的损毁及传统土地复垦方法存在的弊端,阐述了边采边复理论和基本设计,并基于实例对传统复垦进行了对比分析。边采边复是以井工开采沉陷与土地复垦措施耦合为主要目标的新型复垦方法,更适用于高潜水位地区采煤沉陷土地的恢复。其关键技术在于复垦时机的把握,复垦标高的设计和复垦范围的确定,最终目标使土地恢复率最大化。
The land is easy to be damaged during the process of underground mining.According to the phenomenon and the disadvantages of classical reclamation method,the theory and basic design of concurrent mining and reclamation are analyzed,based on example,the comparative of traditional recla-mation methods is analyzed.Concurrent mining and reclamation method is the new reclamation method based on underground mining and land reclamation,it is more suitable for the recovery of coal mining subsidence lands with high groundwater level.The key of the concurrent mining and reclamation method depends on seizing the opportunity of reclamation,designing reclamation elevation and determining the scope of reclamation.The ultimate goal is to maximize the recovery rate of land.
