Used genetic algorithm (GA) to optimize the network of ventilation in order to avoid artificial convergence and speed up the convergence rate to introduce the Powell algorithm. The Powell algorithm had been integrated into GA. Powell had the effective capacity of solving the local optimal solution. Powell and the cross as a method of choice, a variation of the parallel operator, can be a better solution to the premature convergence of the GA problem. The two methods will be improved to make it an effective combination of hybrid GA called hybrid genetic algorithm (HGA) for the introduction of mine ventilation network optimization and to be used to solve the problem of regulating mine optimization.
