Abstract: In view of the layered occurrence conditions of Changgou manganese deposit，and referring to the long-wall mining idea of coal mine，the single-caving mining method and oblique sublevel concentration coal mining methods are proposed.Compared with the several mining methods，the conclusion is that with the dip angle over 35°，the oblique sublevel concentration coal mining method is effective and with the dip angle less than 35°，the single-caving mining method is practical.The room-pillar method is still useful in special mining condition.The numerical simulations indicate that the long-wall working face with the cyclical footage of 1.6 m can assure safety and high effective production.
