摘　　要：针对三百子煤矿2~#、5~#大倾角煤层,指出了传统上行开采可行性判别方法的局限性及其原因。采用传统＂三带＂判别法与＂壳体结构＂模型相结合的方式,对5~#煤层开采后上覆2#煤层的完整性和连续性进行了研究,最后利用数值模拟得出大倾角煤层上覆岩层的运移规律并对该方法的正确性进行验证。Investigated the feasibility of upward extraction coal mine,the limitations of traditional methods in judging and the reason behind are explored. Based on the geological after the extraction of 5# coal seam beneath by associating the of 2# and 5# steep coal seams in Sanbaizi the reliability and safety of upward mining data,analyzed the integrity of 2# coal seam theory of ＂three zone＂ （such as the caving, fracture,and subsidence zones） with the model of shell structure. Then,numerical simulation was adopted to study the overlying strata movement characteristics and to justify the method forementioned.
