Feasibility Research on Exploitation Protective Pillars under Railway in Linsheng Coal Mine
In order to mine protective pillars under railway (shenyan-dalian) in Linsheng coal mine and solve problem for urgent lack of coal resources, feasibility for exploitation protective virgin coal under railway in Linsheng coal mine and influence on railway were analyzed in this paper. Three projects including full caving method, strip pillar mining method and backfilling method were brought forward, movement and deformation of the surface after mining was predicted based on Probability Integral Method. It presented maximum subsidence, horizontal deformation, horizontal movement, inclined deformation and curvature deformation for each project above. Combining with practical instance of Linsheng coal mine technique and economy comparison these projects were carried through. It is confirmed that backfilling method is the best of project at last, maintenance measures for running of railway after mining were put forward.
