Predictive analysis of coal & gas outbrust area based on ant colony optimization and cloud

The coal and gas outbrust have manifested great significance in the production safety of coal mine. In response to the features of factors which have been affecting coal and gas outburst are quite various and, interaction of them are so highly complicated, this paper has present a feature extraction method for coal and gas outburst area forecast on the basis of ant colony optimization. This method converts the feature selection of intricate multi-factors to parallel combinatorial optimization and global optimization. And then, a coal and gas outburst area forecast model is established with the cloud model. Evaluation and analyses on mine practical data prove that proposed approach are effective and practicable.
