Abstract: Coal and gas outburst is a very complex phenomenon of dynamic disaster in coal mine, where exists a complex non-linear mapping relationship which could not be described with functions between outburst risk and its influential factors. In this paper, from operator theory, the choice of initial parameters is optimised, and genetic algorithm is improved. Mathematical model of coal and gas outburst risk prediction is established, and the improved genetic algorithm was applied to the risk prediction model.

Keywords: coal and gas outburst risk; genetic algorithms; risk prediction; genetic operations; fitness function; penalty function; coal mines; coal mining; mathematical modelling.
