非充分开采条件下地表沉陷预计与可视化研究

为研究深部非充分采动条件下地表移动变形规律,指导矿井安全生产,义煤集团某大型煤矿建立了地表移动观测站,根据地表移动实测数据进行参数的拟合解算,采用概率积分法进行地表移动和变形预计。结合MATLAB仿真技术,实现了煤矿深部非充分采动条件下地表沉陷可视化预计,并实现了地表变形图绘制,为煤矿深部开采地表移动规律研究提供了重要参考。

Research on Prediction and Visualization of Surface Subsidence Under Insufficiency Mining

In order to study the law of land surface movement and transformation under deep insufficiency mining, and then to guide the mine safety production, the surface movement observation station was built in one large mine of Yima Mining Group. Based on the measured data, calculation parameters were fitted; surface movement and transformation prediction were conducted based the probability integration method. Combining with the MATLAB simulation technology, surface subsidence visualization prediction under deep insufficiency mining in coal mines was realized, and the surface deformation figure was plotted. These provide important reference to study law of surface movement in deep mining.
