研究含水层厚度、钻孔孔深、方位角和仰角对钻孔疏放水效果的影响程度.利用灰色关联度法对各个影响因素与钻孔疏放水量之间的关联度进行研究,结果显示:通过灰色关联度计算和对各影响因素与疏放水量之间关联度的比较,钻孔方位角对钻孔疏放水量影响最大,含水层厚度、钻孔仰角、孔深对钻孔疏放水量影响依次减小.通过对各因素与钻孔疏放水量之间关联度的分析,不仅可以有效指导未来的顶板水疏放工作,而且为矿井防治水工作提供了依据.
The influence of aquifer thickness, hole depth, azimuth and elevation angle on the effect of drilling water diversion was studied.The correlation between each influencing factor and the amount of water diversion was studied by gray relational method.The results show that: Through the calculation of gray relational degree and the comparison of the correlativity between each influencing factor and the amount of water released, the azimuth of borehole has the greatest influence on the amount of water diversion and drainage. The thickness of aquifer, the elevation angle of borehole, The influence is reduced in turn.Through the analysis of the correlation between each factor and the amount of drilling water diversion, not only can effectively guide the future roof water dredging work, but also provide basis for mine water control work.
