[Abstract]:The analysis and evaluation of mining subsidence damage is one of the main research topics of mining subsidence. In view of the huge amount of coal pressure in China, the prediction of mining subsidence is done well and the accurate and reliable results are used to guide mining practice. It plays an important role in mining subsidence. Therefore, it is urgent for people to carry out the analysis and evaluation of mining subsidence damage. In this paper, the implementation of the observation scheme and the processing of field observation data are introduced in combination with the analysis project of the surface movement and deformation law of Pan Yidong 1242 (1) working face. Control measurement, connection measurement, daily observation and overall observation of control points and monitoring points. The GPS static and GPS-RTK, high precision electronic level height measurement methods are used to adjust the observation data. Based on the analysis of the measured data of the observation station in Panyidong mining area, combined with the geological mining conditions and the mining subsidence principle, the mining subsidence is calculated, and various kinds of isolines are created according to the prediction results: the subsidence isolines. Tilting isoline, curvature isoline, horizontal moving isoline, horizontal deformation isoline. This involves topographic maps of the pilot area, excavation engineering plans, moving deformation prediction maps, and surface movement and deformation information predicted by using the well top and bottom maps and related software. Three-dimensional virtual reality model and two-dimensional model are generated for mining subsidence in the study area. Based on the anti-deformation ability and subsidence prediction result of base land objects, the statistical function of map is used to make statistical inquiry and over-deformation inquiry to the ground objects in subsidence area, and the influence of mining subsidence on surface buildings is evaluated. To realize the dynamic monitoring and management of surface subsidence to achieve the goal of damage evaluation in subsidence area.
