| Abstract: | In order to prevent and control the impact of coal seam in the mining process of Tangkou Coal Mine,the large-diameter drilling is selected to relieve pressure.By means of theoretical analysis and numerical simulation,the pressure relief mechanism of large-diameter drilling is studied,and on the basis of field measurement,the amount of coal dust,damage and regional stress are analyzed.The results show that large-diameter borehole can effectively prevent the energy accumulation of roadway surrounding rock and reduce the risk of coal seam impact. |
