摘　　要：探讨了大同矿区“两硬”条件下(坚硬顶板、坚硬煤层)厚煤层下分层网下综放开采的顶板结构、压力显现特点,提出了该条件下支架载荷确定方法,对类似顶板条件下的综放开采有一定的参考作用。The characteristics of roof structure and underground pressure behavior of caving mining under metal mesh in thick coal seam with hard roof and hard coal in Datong Mine Field are discussed in this paper. The confirmation method of supports load with these conditions is put forward and this method is referenced for full-mechanized caving mining with similar conditions.

关 键 词：坚硬顶板 坚硬厚煤层 网下放顶煤 支架载荷
