| Abstract: | Numerical simulation model of surrounding rock of floor roadway influenced by mining pressure was built up with FLAC software. The stress distribution of floor surrounding rock, the variation rules of stress during mining and the influence on the distortion of floor roadway surrounding rock were simulated and analyzed. The rational setting of protection pillar and the distortion mechanism of roadway surrounding rock were analyzed and hole-blasting technology was put forward to control the distortion of roadway. |

| Keywords: | dynamic pressure roadway numerical simulation surrounding rock stress hole-blasting |
