摘　　要：本文介绍了悬移支架放顶煤采场围岩运动破坏特点和矿压显现规律，分析了不同围岩条件矿压显现的差异，简要说明了存在厚度较大坚硬老顶且来压步距较大采场进行来压预测预报的必要性。The paper is discussed the fragmenting characteristics and mechanical behavior of strata around a top- coal caving mining face equipped by hanged advancing type supports. The difference of ground pressures under different rock conditions is analyzed. The results descript the necessary to forcast weighting of mining faces with thick and high main roof.
