Drift sand layer was met in the shaft construction of Yulin Coal Mine, and the large water inflow caused water inrush and sand inrush in all shafts, bringing great difficulties to shaft construction, and roof fall and shaft submergence happened many times. Through full analysis of construction difficulty, this paper proposes a feasible solution and managed to cross the drift sand layer and opened a new way of crossing drift sand layer in shaft construction in China.
