摘　　要：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.In order to study the influence degree of the aquifer thickness,drilling depth,azimuth angle and overhead angle on drillhole water drainage,this paper analyzed the correlation degree between various influencing factors and water quantity of drillhole drainage using the method of gray correlation analysis.The results show that based on the gray correlation analysis and comparison of correlation degrees between influencing factors and drillhole water drainage,the impact of the drilling azimuth angle on water drainage quantity is the greatest.The impacts from aquifer thickness,overhead angle of drilling and drillhole depth are decreased in sequence.The analysis of the correlation degree between each factor and drillhole water drainage not only can effectively guide the future mine roof water drainage,but also provide a basis for mine water prevent and control.
