【摘要】：开采沉陷损害分析与评价是矿山开采沉陷的主要研究课题之一,鉴于我国“三下”压煤量巨大,做好开采沉陷预计工作并利用精确可靠的结果指导实践开采,对开采沉陷有着至关重要的作用。这就迫切要求人们开展开采沉陷损害的分析与评价研究工作。 本论文结合潘一东1242(1)工作面地表移动变形规律分析项目,介绍了观测方案的实施、野外观测数据的处理。对控制点与监测点进行控制测量、连接测量、日常观测和及全面观测。采用GPS静态、GPS-RTK、高精度电子水准仪高程测量等测量方法,对观测数据进行平差。根据潘一东矿区的观测站实测数据资料分析,结合矿区地质采矿条件和开采沉陷原理,计算开采沉陷引起的,根据预测结果创建各种等值线：下沉等值线、下沉等值线、倾斜等值线、曲率等值线、水平移动等值线、水平变形等值线。这其中涉及到对试点区的地形图、采掘工程平面图、移动变形预计图,利用井上下对照图和相关软件预计的地表移动变形信息,生成研究区开采沉陷的三维虚拟现实模型和二维模型。根据地物的抗变形能力和沉陷预计结果,使用地图统计功能,对沉陷区地物进行统计查询、超变形查询等,进而评价开采沉陷对地表建筑物的影响程度。实现地面沉陷的动态监测和管理,以达到对沉陷区损害评价的目标。
[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.
