摘　　要：邢台某矿采用地面多分支水平定向钻探技术对奥灰含水层顶部进行区域超前注浆改造,取得了很好的安全技术效果。选取该工程中6个钻孔中的注浆量、钻井液漏失量、平均吸水率和注浆段长度数据,基于灰色关联理论和回归分析方法,对原始数据进行分析,得到注浆量及其相关因素的回归方程,为优化注浆工艺、保障煤矿安全生产奠定基础。A mine in Xingtai uses the ground multi-branch horizontal directional drilling technology to carry out regional advance grouting transformation on the top of the Ordovician aquifer ,which got excellent safe technology effect. The amount of grouting, the loss of drilling fluid, the average water absorption and the length of grouting section in six boreholes in the project are selected. Based on the grey correlation theory and the regression analysis method, the original data were analyzed to obtain the regression equation of grouting volume and its related factors,which lays the foundation for optimizing the grouting process and ensures the safe production of coal mines.
