在“计算移动和变形的经验分析方法”一文(苏联高教通讯采矿杂志1972年第11期第56～59页)中,曾提出了在接近充分采动条件下开采缓倾斜煤层时,计算地表移动与变形的经验分析法。倾斜及急倾斜煤层条件下,以地表最大下沉点(或者是移动盆地平底边缘)作为计算坐标的原点是适宜的。当移动过程比较平稳时,可以用下面形式的高斯积分函数作为下沉曲线方程:
In the article entitled “Empirical Analyzes of Movement and Deformation” (Soviet Union Journal of Mining and Communication, No. 11, pp. 56-59), it has been proposed to calculate the movement of the ground surface when mining gently inclined coal seams under the condition of near full mining And deformation of empirical analysis. Under the conditions of inclined and steep coal seams, it is appropriate to use the maximum sinking point (or the flat bottom edge of the moving basin) as the origin of the calculated coordinates. When the moving process is relatively stable, the following form of Gaussian integral function can be used as the sinking curve equation:
