Abstract: The auxiliary shaft of Guotun coal mine adopts the comprehensive water controlling techniques of grouting surrounding rock,internal and external shaft wall rock.The shaft station employs the grouting method using high-stress grouting anchors.The temporary water sump uses the method of stopping drivage and setting grouting pad for grouting.These three grouting methods obtain positive water plugging effects,having a positive significance on water controlling of the deep shaft.
