分析了长壁采空区上方覆岩的基本性态，采用相似材料模拟试验研究了老采空区上方兴建建筑物后地基的沉降规律，得出了一些有益的、对老采空区上方地表建筑物设计有一定参考价值的结论
The basic behavior of the overlying strata above the longwall mined area was analyzed. The similar material simulation experiment was used to study the settlement of the foundation after the construction of the buildings above the old mined area, and some beneficial lands were obtained on the old goaf. The conclusion that building design has certain reference value
