| Abstract: | Based on the characteristics of intense deformation-failure of surrounding rock in a soft and thick coal seam roadway along gob area coal mine,the structure calculating model of original rocks around a roadway along gob area is constructed by knowledge of mechanics,and various bolt-mesh-anchor supporting schemes are simulated and supporting parameters optimized,supporting schemes is proposed,which is secure and economic.The results of both numerical calculations and in-situ tests show that this technology of U-steel supports and backfilling(in the top area of roadway) can satisfy the requirement of engineering,and better economic and social profits have been achieved. |
