Study On Villages Moving Planning In Mining Subsidence Area Based On GIS

As a result of the rapid development of our country national economy, the energy need is a great deal of increment. Along with coal resources massive mining, the problem of coal under villages becomes more and more outstanding, and influences the normal production of the more mines enterprise. Moves village mining is one of the general methods that mining under villages. Therefore the research of villages moving planning in mining subsidence has important significance for normal exploitation of mining area.The paper through discusses each method of mining under villages, and buildings protective measures and damage evaluate, and content method of villages moving planning etc, on this foundation carried out an mining subsidence area villages moving planning research, and has developed the mining subsidence area villages moving planning information system which taken MapInfo as apply platform and VB as the develop tool. The system integrated surface movement and deformation predication, buildings damage evaluation, moving project evaluation, villages moving planning to provide technique guarantee and decision support for the mining area villages moving planning, and applied this to villages moving planning in the Longgu mining subsidence area and obtained the good effect.The paper selects fuzzy synthetical evaluation method to compare strip ming with moving villages mining which often used ming under villages, and considers synthetically the technique factor, economy, society, and the environment performance index, and avoid one-sidedness only consider economic benefits. The paper according to different buildings has different ability to bear surface movement and deformation. But currently have no suitable index which expresses the size of the withstanding deformation ability. So the paper according to building of high long ratio, the shear strength and the tensile strength of the wall put forward building vulnerability index to show the measure of building withstanding destructive ability under the surface movement and deformation influence.
