摘要:
为解决煤矿在施工过程中局部防突问题，进行现场实测并结合数值模拟计算，研究瓦斯排放钻孔影响半径在不同排放时间和不同超前钻孔直径影响下的变化规律。研究结果表明：对于同一孔径的钻孔，在一定时间内影响半径随着时间的增加而增加，不同直径的钻孔呈不同的函数关系；对于不同的孔径，影响半径随着钻孔直径的增加而增加，研究结果可为矿井作业中治理煤与瓦斯局部突出提供重要参考。
Abstract:
In order to solve the problem of local outburst prevention in the construction process of coal mine,the field measurement and numerical simulation were combined to study the variation laws of the influencing radius of gas drainage borehole under the influence of different drainage time and different advanced borehole diameters.The results showed that for the boreholes with the same diameter,the influencing radius increased with the increase of time in a certain period of time,and the boreholes with different diameters presented different functional relationships.For the boreholes with different diameters,the influencing radius increased with the increase of borehole diameter.The conclusion provides important reference for the control of local coal and gas outburst in the mine operation.
