本文在采用弹塑性有限单元法模拟的基础上,得到了多煤层条带空间位置与岩层及地表移动间的关系。给出了下沉系数q、水平移动系数b,主要影响范围角正切tgβ与上、下煤层条带间水平错距l、层间距h、累计采厚m的计算公式。根据这些计算公式计算的结果与实测相比符合较好。 Based on the finite element method of elasto-plastic simulation, the relationship between the spatial position of multi-seam strata and the movement of rock strata and surface is obtained. The formulas of the settlement coefficient q, the horizontal movement coefficient b, the main influence range angle tangent tgβ and the horizontal and vertical displacements l between the upper and lower coal seam bands, the interlayer spacing h and the cumulative mining thickness m are given. The calculated results based on these formulas are in good agreement with the measured ones.
