近距离薄煤层条带开采是“三下”开采中控制覆岩移动变形和地表沉陷的有效方法之一，提高煤炭资源回收率，同时减少煤矿开采对矿区环境、地表破坏的影响，具有重要的理论意义和应用价值。本文采用数值模拟方法研究了近距离薄煤层条带开采引起的地表变形特征，结果表明：当采出率为50％时条带方案选取采40m留40m时最为合适。
近距離薄煤層條帶開採是“三下”開採中控製覆巖移動變形和地錶沉陷的有效方法之一，提高煤炭資源迴收率，同時減少煤礦開採對礦區環境、地錶破壞的影響，具有重要的理論意義和應用價值。本文採用數值模擬方法研究瞭近距離薄煤層條帶開採引起的地錶變形特徵，結果錶明：噹採齣率為50％時條帶方案選取採40m留40m時最為閤適。

The strip mining in short - distance thin coal seam is one of the effective methods controlling displacement deformation of overlying strata and surface subsidence in coal mining under buildings and railroads and water bodies. The method has a great theoretical significance and application value by increasing recovery rate of coal resources and cutting down the effect of coal mining on environment and surface of mining area. The numerical simulation method is adopted to study the surface deformation characteristics by the strip replacement mining in short - distance thin coal seam. Such conclusions are drawn as follows： the strip project of forty meters mining with forty meters reserving is quite suitably selected while half of mining rate.
