Water inrush dangerousness evaluation of coal floor from SDM

The floor water inrush is a geology hazard in China. Tt is a complex nonequilibrium and nonlinear evolution process which is affected by many factors. Spatial Data mining (SDM) can reveal spatial patterns and features of water inrush. With the SDM technique, the water inrush dangerousness of 9# coal floor of zhangcun coal mine was evaluated. The result shows that the SDM technique is a feasible effective method to evaluate water inrush dangerousness of coal floor.
