摘要：

With the formation mechanism of conductor on floor water-inrush as the division criterion, the floor water-inrush patterns in deep mining was divided into three categories: the whole aquifuge type, the buried structure type, and the intrinsic conductor type. The introduction of cusp catastrophe model into the whole aquifuge type and the intrinsic conductor type built the butterfly catastrophe model which was applied to the buried structure type. The catastrophic characteristics of floor water-inrush hazard in deep mines were analyzed based on the geometric properties of the equilibrium surface of the cusp catastrophe model. This study has shown that 1). From time perspective the water-inrush hazard of floor strata in deep mines has the character of burstiness and lagging; 2). From space perspective, catastrophe paths of the hazard in the floor strata have the character of diversity, and the water-inrush location in the buried structure type and the intrinsic conductor type has its regularity. © 2017, Editorial Board of Journal of Mining & Safety Engineering.
