摘　　要：针对综放工作面矿压显现有其自身的特点的问题,通过结合王坪煤矿东Ⅰ5802综放工作面的地质条件,采用数值模拟的方法,对该工作面围岩应力与位移的分布进行研究,得出工作面前方煤体在支承压力的影响下产生了垂直位移与水平位移,随着深入煤体深部,其位移都在减小。支架上未放出的煤体其垂直位移与水平位移较大。顶煤的水平位移可能造成支架的倾倒于下滑,实际开采过程中应采取必要的治理措施。该结果为实现高效回采与有效支护提供了基础。In view of workface pressure behavior having its own characteristics of the problem,through a combination of Wang PingⅠ5802 coal caving face of the geological conditions,using numerical simulation method,this working face surrounding the distribution of stress and displacement of,come in front of the face support pressure of coal produced under the influence of the vertical displacement and horizontal displacement,with the deep depth of coal,its displacement are reduced.Support the coal is not released its vertical displacement and horizontal displacement of large.Horizontal displacement of top coal dump the stent may cause decline,the actual mining process should take the necessary control measures.The results for the realization of efficient mining and provide the basis for effective support.
