摘要
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。
To find out a solution of thick coalseam extraction under buildings, the central strip and side longwall mining method is investigated by FLAC 3D numerical analysis. The subsidence, deformation and fracture to the surface land caused by the method are studied. The rational mining measures for protecting of the buildings are proposed.
