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。
In order to study the law of surface movement and deformation under deep mining conditions and guide mine safety production, a large-scale coal mine of Yi Coal Group has established a surface movement observation station, fitted and measured the parameters based on the measured data of surface movement and adopted the method of probability integration Surface movement and deformation prediction. Combined with the MATLAB simulation technology, the visual prediction of surface subsidence under the condition of insufficient fully mechanized mining in the coal mine is realized, and the drawing of surface deformation diagram is realized, which provides an important reference for the study on the law of surface movement in deep mining of coal mines.
