摘要:
针对矿井在施工排放钻孔局部防突措施时,已知排放时间,如何确定排放钻孔孔径和钻孔间距这一难题,提出一种钻屑量和钻屑瓦斯解吸指标现场测试法,结合数值模拟计算,确定不同孔径排放钻孔有效排放半径随时间的变化规律。研究结果表明:同一孔径排放钻孔,随着排放时间的增加,有效排放半径呈幂指数增大;不同孔径排放钻孔,随着排放钻孔直径的增加,有效排放半径呈幂指数增大。研究结论对矿井选取合适的排放钻孔孔径及布置参数具有指导意义。
Abstract:
Aiming at the difficult problem for the mine to determine the drainage borehole diameter and borehole spacing under given drainage time when constructing the local outburst prevention measures of drainage borehole,a field test method for the amount and the gas desorption index of drill cuttings was proposed.Combined with the numerical simulation calculation,the variation laws of the effective drainage radius of drainage borehole with different diameters against time were determined.The results showed that for the drainage borehole with the same diameter,the effective drainage radius presented the power exponential increase with the increase of drainage time.While for the drainage borehole with different diameters,the effective drainage radius presented the power exponential increase with the increase of diameter of the drainage borehole.The results have the guiding significance for the mine to select the appropriate diameter and layout parameters of drainage borehole.
