Based on cusp catastrophe characteristics of water inrush from floor, a cusp catastrophic mechanical model of a key stratum of floor is established by catastrophe theory. By the model, the paper analyzes mechanical mechanism of water inrush from key stratum of floor with the cusp catastrophic theory. Using an engineering example, the numerical simulation proves that this method of the theory analysis is practical.

Catastrophic Model

The water inrush from coal mine floor is a typical catastrophic process. A catastrophic theory is applied to water bursting in pit footwall for the first time. Through the research on lost stabilization of energy in the floor system of coal mine, a cusp catastrophic model applied to forecast water bursting from coal mine floor is put forward. The formulas of the critical stress, the strain and the released energy of the floor are developed when the floor system lost stabilization. So a new theory approach is offered for the forecast of water inrush from coal mine floor.
