摘　　要：针对义马煤业集团常村煤矿2107-2综放工作面的开采条件,利用深基点跟踪观测法,探讨了孤岛工作面在顶分层已采条件下综放开采时顶煤变形运移特征,对类似地质条件工作面采用综放开采时确定合理的生产工艺参数提供了依据。Aiming at the mining condition of No. 2107 - 2 fully mechanized top - coal caving face in Changcun Mine of Yima Coal Mine Group Corporation, by means of deep base point tracing measurements, the paper probes into the top - coal deformation and movement features of the isolated island working face under the conditions of pre mining top slicing, which provides the gist for determining reasonable production technology parameters under the similar geological conditions while using the fully mechanized top - coal caving mining.
