摘　　要：纳一矿三盘区6-2上04、05、06工作面已开采完毕,下层6-2煤3个工作面即将布置,该煤层平均厚度3.5m,与已经回采完毕的6-2上煤层间距平均0.8m左右,本文将通过理论分析、数值模拟对极近距煤层回采巷道常用的四种布置方式:内错布置、外错布置、内外错组合布置、重叠布进行分析,得出纳一矿6-2号煤层适宜内外错组合布置方式。Mine Carolina 6 -2 on three zones 04,05,06 Face has been depleted, the lower face in the upcoming 6 -2 3 coal arranged the average coal seam thickness 3.5m, and has completed 6 - 2 coal seam mining the average distance of about 0.8m, this article by theoretical a- nalysis and numerical simulation of a very close four common seam roadway arrangement ： Staggered arrangement arranged outside the mistake, the wrong combination of internal and external arrangement, overlapping cloth analyzed to give the cashier a mine No. 6 - 2 and outside the wrong combination of seam suitable arrangement.
