摘 要: 在建立陷落柱顶端力学模型的基础上,应用突变理论方法,建立了陷落柱顶端突水的尖点突变模型,得出了陷落柱顶端突水的充要条件表达式。根据模型对陷落柱顶端突水机理进行分析,认为影响陷落柱是否发生突水的主要因素有陷落柱的尺寸、顶端岩层的性质、陷落柱的埋深、承压水压力以及矿山压力等参数。该模型的建立对判断和预防陷落柱突水具有积极意义。
关 键 词: 采矿工程;尖点突变模型;突变理论;陷落柱;突水

Abstract: A mechanical model of collapse column top is established, based on which, the expression of total potential energy function is derived. Then the cusp catastrophic model for the water-inrush of collapse column is set up by catastrophe theory. The formula of necessary and sufficient condition for the water-inrush of collapse column is obtained according to the cusp catastrophic model. In the mean time, the mechanism of water-inrush from top of collapse column is analyzed according to the model. The cusp catastrophic model indicates that the main factors of affecting the water-inrush include the size of collapse column, the nature of top strata, the depth of collapse column, the pressure of confined water, the mine pressure and so on. The establishment of model is of great significance to judge and prevent the water-inrush of collapse column.
Key words: mining engineering; cusp catastrophic model; catastrophe theory; collapse column; water-inrush
