摘　　要：朱家河煤矿自投产以来 ,采场支护顶板管理困难 ,顶板事故频频发生 ,严重地影响着矿井的安全生产。论文通过对矿井地质构造、 5 - 2煤层赋存条件的综合分析 ,并通过煤矿5 - 2煤层顶板岩层结构、岩性 ,及其岩石的力学性质试验分析 ,确定 5 - 2煤层顶板类型 ,提出5 - 2煤层合理的顶板支护管理方法 ,为 5 -Since Zhujiahe mine has been put into production,it is difficult to manage the roof of goaf,and the disaster of the roof happens frequently,which affect the production of the mine severely. This paper defines the class of roof,and puts forward the reasonable management method about 5-2 coal seam in Zhujiahe mine,and further provides the basis for the roof management and the safety of the mine production by analyzing the geology structure,the condition of the 5-2 coal seam,the structure of main roof of the 5-2 coal seam and the lithology and the character of the mechanics of rock.
