| Abstract: | Starting with the improving of the prediction speed and precise of gas emission quantity at mining faces,the authors put forward a BP neutral network model for optimizing both the network link weight and topologic structure with a genetic algorithm.Taking Hancheng Xiayukou coal mine as an example,a practical application method is given.The results shows the model is of a higher precision and application prospect. |
