The Supporting Research on 40110 Working Face Transport Tunnel of Dafosi Coal Mine

摘要

40110 working face is located in CaiZiYuan Chengguan town of Binxian county. It is arranged as the third mechanized mining caving working face. According to the geological characteristic in the area, it was researched on the roof and floor lithologic, structure, hydrology, gas, dust features and so on, and devised mining tunnel supporting about tunnels, section, horizon, support instructions by experience, calculating, analysis. Practical result shows that the two sides displacement and relative movement of the roof and floor effectively controlled to ensure the daily production of coal mine by the tunnel supporting design.
