摘　　要：开展了在相同地质条件下厚煤层分层开采和大采高一次采全厚开采时的相似材料模拟对比实验,研究了开采高度为3.5 m和6.0 m时工作面来压步距、岩层垂直位移量、关键层层位和"上三带"分布范围等,总结分析了其不同的矿山压力显现规律。The simulation contrast test on similar materials was conducted in the same geological condition between thick-seam layer mining and large-mining-height overall height mining in one time. The weighting interval, strata vertical displacement, key seam position, and distribution of ＂upper three zones＂, when mining height being 3.5m and 6.0m, are studied in detail. At last, the different mine pressure behaviors are concluded.
