摘要
通过对平顶山煤业集团公司八矿多煤层采区同采条件下，下部煤层开采对上部煤层开采影响的相似材料模拟试验结果的分析，得出了下组煤层开采时上覆岩层的移动及变形规律、有关岩层移动参数。
According to the analyzed results of similar material analog test of the influence of upper seam mining upon lower seam mining under the simultaneously mining conditions of multiple seam blocks in the No 8 Mine of Pingdingshan Coal Bureau, the authors got overlying strata movement and deformation pattern, related strata movement parameters during lower coal seam mining, prediction method of upper coal seam drift deformation, and temporal and spatial relation of mining_induced influence.
