| Abstract: | Based on the mining gateway deformation in three soft coal seam,corresponding deformation mechanisms are analyzed.Some policy suggestions on controlling and reducing the deformation of surrounding rocks are put forward.And a optimized scheme of belt and rope support to the mine is designed.So minimizing the cost of inputs can obtain perfect support result. |
