Impact Analysis of Different Mining Sequence and Recovery Rate on Road Bed Stability in Inclined Coal Seam Area

Li Haixi(Shanxi Provincial Communications Planning Surveying & Design Institute,Taiyuan 030012,China)  
According to the complicated condition of goaf,relying on the real project,using the two-dimensional finite element numerical analysis method reflecting the actual problem,using nonlinear elastic-plastic finite element technology,the failure rule of subgrade degeneration due to coal seam mining by different sequence and recovery rate,to seek a way to prevent discontinuous deformation and subsidence of subgrade,and to provide technical basis for reasonable design.Research shows that: different coal seam mining sequence has different influence on the subgrade.Improper selection of mining sequence will give serious harm to the subgrade;On the other hand,change the mining sequence of the seam and the working surface can also achieve the purpose of coordinating mining,and the deformation can be offset partly.With the increase of the recovery rate,the vertical displacement increases with a high increase rate;The maximum horizontal deformation will be rapid grown;The scope of mining subsidence basin will be expanded with the increase of the mining width.
