The complex occurrence state and morphology of the thin to mediumthick complex and hard-to-mine ore bodies in Xintai mining company make the ore bodies hard to mine.The study takes Tudui Mining District as the engineering background,and carries out optimization with anti-inclination approach overall mining method.The mining preparation system is reasonably laid out,the stope structure parameters are optimized,the control blasting technique of large borehole distance and small resistance line is used and the mining loss and ore dilution are reduced production capacity is improved and lower production cost is lowered.Industrial application results show that the use of the optimized mining method improves mining efficiency by 35 %,lower ore dilution rate by 17.28 percentage points and mining loss rate by 11.26 percentage points.The technical and economic outcome is evident and the resources are utilized in a safe,environment-friendly,economic and reasonable way.
