为解决建筑物下厚煤层开采技术难题，提出中央条带两冀长壁特殊开采方法，通过三维有限差分数值计算（ＦＬＡＣ３Ｄ），对该开采方法造成的地表变形和破坏进行了预测分析和探讨，阐述了保护地面建筑的合理开采措施。
In order to solve the technical problems in the mining of thick seam under buildings, a special longwall excavation method with two bands in the central strip was put forward. Through the three-dimensional finite difference numerical calculation (FLAC3D), the deformation and failure of the ground surface caused by the mining method were predicted and analyzed. Describe the rational protection of ground construction of the mining measures.
