Abstract: In view of the problem of large and sustained investment for coal mine mechanical and electrical equipment management did not effectively reduce the loss of electromechanical accident, an optimization model is established which use the minimum loss of electromechanical accident as the goal, and the resource input as the constraint, and on the basis of this, the inverse optimization model is established.At last,the model was used for a certain coal mine enterprise’s electrical and mechanical equipment management,and the result showed that the inverse optimization method can meet the new requirements of the system by adjusting the resource input constraints, which offered a new way to optimize the resource allocation of coal mine mechanical and electrical equipment management.
