摘　　要：利用ＡＤＩＮＡ程序对顶煤进行了二维有限元应力分析，得到了顶煤破碎发展区域“三带”量的概念，为顶煤的破碎机理分析提供了依据。This paper carried out two dimentional finite element analysis of the stress distribution of the top coal using the ADINA program. Through analysis,the concept of 'three-zones'which were formed during the failure process of top coal was established.It provides a basis for analyzing the failure mechanism of the top coal.
