| Abstract: | This paper studies the mine pressure appearance in roadwayS for steep--dip critical-angle short-distance thin and midium-thickness seam grouped combined mining in aspects of both natural and mining factors.By data collection, reduction and analysis, the optimal malposition distance and mutual influence ranges of simultanuous adning upper and lower coal groups, upper and lower blocks and upper and lOwer seam in a group.So, the scientific basis of mine production is provided. |
