Study On The Key Problems Of Expropriation And Resettlement Information Platform With Integrated Supervisory On Land And Mineral Resources In Mining Area

Expropriation and resettlement management in mining area defined by thisdissertation should take underground coal resources and overground land resourcesinto account, while currently the two kinds of resources were separately managed.Therefore, the concept of expropriation and resettlement with integrated supervisoryon land and mineral resources in mining area was defined. Under summarizing thedomestic and overseas research progress, the research emphasis of this dissertationwas listed as follows.(1) Based on analyzing the shortcomings of conventional requirement analysismethod, the progressive refinement method representing use-case diagram and classdiagram was adopted to design the expropriation and resettlement supervisoryplatform (ERSP), and corresponding guarantee mechanism was utilized.(2) The expense payment models of expropriation and resettlement weredesigned coupling with multiple patterns, which not only assured the sharing andreusing of business modules, but also assured the expansibility and modifiability ofthe models.(3) COM plug-in techniques were adopted to fulfill the design and developmentof LMSP plug-in framework engine, which means that each programming languagesupporting COM component (such as VC++, C#, etc.) can be used to extend thefunction modules of ERSP host framework. The engine can not only have thecharacters of stability and easy maintenance, but also do benefit to team development.(4) The definations and network data exchange mechanism of expropriation andresettlement patch and event were put forward, and the completed subsystem of DSSand DES can partly substitute the manual data report work.(5)“Patch change method” as a new measurement of land use change analysis ofexpropriation and resettlement was brought forward, which was designed with codingrules, checking rules and analyzing steps, and corresponding software aidedmeasurement and checking was developed. (6) Based on the customized point primitive, triangle primitive, polygonprimitive and3D terrain surface model,3D visualization system of mining damage(MDVS) was fundamentally developed. The efficiency of3D interactive volumnmeasurement algorithm was enhanced largely by locality improvement of Grahamalgorithm and definition of the bounding rectangle of land subsidence basin.
