It is critical to solve the supporting problem of deep auxiliary shaft ingate. Based on the surrounding rock qualities, geological condition and other supporting factors of Xingyue mine＇s shaft ingate, the anchor supporting parameters were preliminarily determined by field measurement, theoretical analysis and engineering analogy. Through FLAC-3D （numerical simulation software）, surrounding rock deformation and damage were studied and the parameters were optimized. At last, a supporting mode was selected. Field practice showed that its parameters were reasonable and supporting effect was ideal.
