The utility model provides an exploitation working face goes upward, arrange in upper portion coal seam (1), including open -off cut (2), haulage drift (3) and return aircourse (4), haulage drift (3) are arranged in haulage drift outer region territory (7) of having adopted of lower part coal seam (5) working face (6), directly over the haulage drift or haulage drift inside area territory (8), when haulage drift (3) arranges in haulage drift inside area territory (8), haulage drift (3) do with the expression formula of adopting the probe distance L1 of working face haulage drift (9): < hcot psi 3 for L1. The utility model discloses can effectively reduce the width that the tunnel keeps apart the coal column, guarantee the working face production safety simultaneously, and then effectively improve exploitation working face goes upward's the rate of recovery.
