The colliery roof collapse accident is one of the mine disasters .The influence factors have the characteristic of variety, non-linear, incertitude, etc., which make traditional neural prediction have to process a large amount of convoluted data. This paper gets cluster center and subjection degree through combine ant colony with fuzzy C mean value clustering algorithm, establishes the dynamic system distinguish mode that suits for non-linear form with recurrent fuzzy neural network, it obviously reduces the calculation complexity of the algorithm.
