摘　　要：采用FLAC数值模拟软件,系统地研究了多煤层条带开采中不同采深、不同采宽、不同层间距和上下煤柱的空间位置关系对地表下沉和水平移动的影响规律,给出了地表最大下沉、最大水平移动与采深、采宽、层间距及上下煤柱位置的函数关系式,建立了地表最大下沉和最大水平移动的综合影响关系式.Based on the FLAC numerical simulation software, the laws of the surface subsidence and horizontal movement in multi-coal seam strip mining were studied systemically for the different depths, different mining widths, different distance between seams and the special relations of the upper pillar and the lower pillar in vertical direction. The function relations between the maximum subsidence, the maximum horizontal movement and above factors were given. Finally the formula indicating the integrated effects on the maximum surface subsidence and the maximum horizontal movement was deduced.
