Research Of Liaoning Province Zhangwu Leijia Coal Mine Land Reclamation Project

This thesis combined with natural situation of Leijia coal mining area in ZhangwuLiaoning.Land destruction period was divided into two stages according to constructionand production timing,that is the stage of land directly destruction during constructionperiod and the stage of land destruction due to mining subsidence duringproduction.Waste dump、 industrial square、 storage soil field、 external road andsubsidence area were used as destruction unit,the destruction type are pressure、diggingloss and subsidence.The influence to ecological environment and aquifer caused byengineering construction and production of coal mine were analysised.Meanwhile,theinfluence to ecological environment、land resources and biological caused by surfacesubsidence、pollutant emission and mining were analysised.The limiting condition andinfluencing factors of land reclamation in mining area were obtained according tosuitability evaluation and analysis of land reclamation.On the basis of this,reasonablepreventive and control measures and engineering reclamation measures were made.Reclamation direction was determined as cultivated land、garden plot、forest land&fishery land.Reasonable reclamation and its plan arrangement were made according tovarious measures.
