摘　　要：窄条带厚煤层工作面初采期间老顶活动频繁,顶板管理困难,安全隐患较大,通过对济三矿13下05C综放面初次放顶的矿压观测分析研究,为类似条件工作面巷道布置、顶板管理、矿压规律研究等起到了很好的借鉴作用。Even the narrow stripe work face with thick coal seam was mined . The main roof behavior was frequenent the roof control was hard and had much hidden safe trouble. According to analyze Ji - san coal mine 13down05C first caving pressure observation can provide reference for similarity arranging roadway and roof control and pressure behavior analysis .
