| Abstract: | In this article, the author did researches on the technology of sub-seam lane support under the coal seam within very close distance in Si Laogou Mine of Tong Ming Group, adopted the method of double combination of support in the sub-seam with the layer thickness of 0.8 to 2.0 m, successfully supported the lane roof and achieved the expected effect of supporting. This will have important application and reference value for the support of digging work face in sub-seam under very close and close coal seam. |
