针对赵固二矿11050工作面采高达6 m、基岩薄,并且在工作面回采过程中,煤壁片帮、冒顶等矿压显现明显的具体情况,采用相似模拟试验的方法,研究了薄基岩大采高工作面的覆岩移动规律。结果表明覆岩破坏高度与工作面推进长度呈线性关系,整体呈现阶梯状分布。 In view of the fact that 11050 face of Zhaogou No.2 coal mine is up to 6 m in height, the bedrock is thin. In the process of face mining, the rock pressure of coal wall, top collapse and so on are obvious. The similar simulations are used to study the effects of thin Overburden Strata Movement Regularity in Large Cutting Height Working Face of Bedrock. The result shows that there is a linear relationship between the failure height of the overburden and the propulsion length of the working face, and the overall shape of the staircase is distributed.
