本文是根据抚顺矿区二十多年来的实际观测资料,以相关分析的方法,最小二乘法原理,导出了在特厚煤层水砂充填开采条件下的,用指数函数表示的下沉盆地的移动和变形经验公式。文章着重论述下沉盆地稳定以后的地表移动与变形的最大值,以及地表点移动速度与时间过程的分析和计算,经理论与实测资料的对比,完全符合精度要求。
This article is based on the actual observation data of Fushun mining area over the past 20 years, and by the method of correlation analysis and the principle of least square method, the movement of the subsidence basin expressed by exponential function is derived under the conditions of water sand filling and mining in the special thick coal seam And deformation experience formula. This article focuses on the maximum of the surface movement and deformation after the stabilization of the subsidence basin, as well as the analysis and calculation of the moving speed and time course of the surface point. The comparison between theoretical data and measured data fully meets the requirements of accuracy.
