Application of improverd BP network in the prediction of coal and gas outburst

摘要

For reasons of the complex, the uncertainty and the fuzziness between outburst- disaster and outbursts-factors, it appears difficult to realize accurate prediction of coal and gas outburst. With powerful "information mapping" function and set-study capability, Back Propagation Network (BP Network for short) makes it possible to perceive, distinguish and capture the interrelated pattern of the outburst-disaster with the outbursts-factors objectivley and really, and could be hopefully used to realize exact prediction of the coal and gas outburst.
