摘　　要：本文针对淮北矿区朱庄煤矿Ⅱ646综采工作面可能面临的顶板大面积断裂和垮落特征,通过相似模拟实验,对顶板的变形和垮落特性做了具体研究,得出初次来压步距84 m和平均周期来压步距31 m的规律,且回采期煤层顶板运动可划分为六个区。从而为某煤矿Ⅱ646综采工作面坚硬顶板的处理提供理论依据。The paper according to the characteristic of Huaibei Zhu Zuang Mine Ⅱ646 mechanized mining may face a large area of the roof caving, through similar simulation experi-ments, and a specific study of the roof caving deformation’ s characteristics, drawn from the 84 first weighting m and the av-erage cycle weighting step 31 meters of the law, and the mining of coal seam roof movement can be divided into six zones. So as Zhu Mine Ⅱ646 mechanized mining face hard roof processing to provide a theoretical basis.
