摘　　要：近距离多煤层条带开采在工作面布置不合理时易造成相互叠加影响和煤柱的失稳,进而影响条带开采的减沉效果。在多煤层条带开采设计时需要充分考虑煤层间距等地质采矿条件,尽可能减小上下煤层之间的影响,确保设计方案达到预期减沉目标。依据多煤层条带开采地表移动理论,结合设计区域地质采矿条件进行了村庄下近距离多煤层条带开采方案设计。预计表明,设计方案可以有效保护地表建筑物。Cumulative influence and coal pillar instability could be induced by unreasonable layout of working face with strip mining under multiple coal seam with closed distance, then reducing subsidence effect of strip mining would be influenced. The geological and mining situation, such as interval distance of coal seam should be considered fully for strip mining designing with multiple coal seams,the influence between top and bottom coal seam should be decreased as far as possible, and the prospective reducing subsidence aim of design scheme must be ensured. According surface movement theory of strip mining with multiple coal seams, and the strip mining scheme of multiple coal seams with closed distance under village was designed under geological and mining situation of designing area.It predicts show the designing scheme could protected surface structures effectively.
