Research Method Practice of Mine Pressure Law in Fully Mechanized Coal Mining Face

本文以中兴煤矿1208综采工作面为背景,分析了不同推进距离下工作面支架受力情况、端头支护单体支柱情况及巷道的断面收缩情况,得出了1208工作面的周期来压歩距及巷道变形量与工作面距离的相互影响关系,为工作面的顶板管理提供了技术支撑。

On the background of 1208 fully mechanized coal mining face in Zhongxing Coal Mine,this paper analyzes the force situation of the working face support,the condition of the end support single body support and the section shrinkage of the roadway under the different propulsion distance,and obtains the mutual influence relationship between the interval of the 1208 working face and the deformation amount of the roadway and the distance of the working face,which provides technical support for the roof management of the working face.
