通过多煤层同采时下部煤层开采对上部煤层开采影响的试验结果分析，得出了试验矿井条件下，下部煤层开采时上覆岩层移动及变形规律、有关岩层移动参数，并提出了上部煤层巷道变形的预计方法．图４，表２，参３． Through the analysis of the experimental results on the influence of the lower coal seam mining on the upper coal seam mining during the same coal seam mining, the movement and deformation rules of the overlying strata, the related rock movement parameters under the conditions of the experimental mine and the lower coal seam mining are obtained, and the upper coal seam roadway The expected method of deformation.
