孝义铝矿土地复垦的实践

孝义铝矿矿区范围大，其开采占地速度快，而征地困难。为此，在露天开采的同时，进行了大量土地复垦技术研究，形成排土场和采空区的适宜复垦技术方案。经过复垦和培肥熟化，复垦土壤的肥力和主要性能达到了当地一般土壤标准，其农作物产量接近或超过了当地同种农作物的产量。

Practice of Land Reclamation in Xiaoyi Bauxite Mine

In Xiaoyi Bauxite Mine, the limits of mineral region are large, and the land occupation is rapid in mining the bauxite deposit, but it is difficult to purchase land. Therefore, while open mining this deposit, a vast amount of technical research on land reclamation has been carried out,and suitable technical programs of the reclamation of mined area and dump pit have been deveilopted.Through the land reclamation, fertilization of soil and soil ageing, in the reclaimed land the fertility and principal performances of the soil have achieved the general soil standard of the locality, the yield of the corps planted in the reclaimed soil is close or more than that of the small kind corps planted in local natural soil.
