摘　　要：为了解决目前地质勘探报告、矿井生产报告中煤层顶板岩性、厚度取值中存在的问题,通过分析各类煤层顶板的定义,探讨目前顶板划分中存在的问题及其原因。提出了解决方法,并对各类顶板进行了重新定义,从而规范统一对顶板的划分。该方法和定义对勘探阶段、生产矿井阶段煤层顶板稳定性评价、巷道掘进、顶板支护控制具有指导意义。In order to solve the problem existing in the lithology and thickness of coal seam roof values in geological exploration report, mine production at present, through analysing the definition of the coal seam roof, the existing problems of the classification of the coal seam roof were discussed, and the reasons were also studied. The solution was proposed, all kinds of roof were redefined, whose purpose was to unify the division of coal seam roof. The results show it has more guiding significance to evaluate stability of the mine coal seam roof and roadway drivage and roof support control in the process of exploration and production.
