| 英文摘要 | North China type coalfield karstic collapse column water inrush is the most serious potential issue for coalmine production safety, as the water inrush quantity is significantly huge and destructive. However, research on karstic collapse column water inrush mechanism, water inrush process and mechanical model of water inrush is still in its infancy. In this paper, based on heterogeneity assumption of the collapse column overburden layer and shear failure theory, we established a water inrush mechanical model of strong conducting (water including) karstic collapse column of different cross section types. Besides, the critical condition of strong conducting (water including) karstic collapse column water inrush, which is caused by Ordovician confined water stress and mining stress during mining process, was established. Meanwhile, the water inrush risk coefficient is proposed and utilized to evaluate the karstic collapse column stability of water inrush resistance. Theoretical derivations and numerical analysis indicate that strong conducting (water including) karstic collapse column water inrush is a complex processes related with the column cross section shape, critical thickness of water-resisting layer, and rock physical properties. The work in this paper indicates that column section shape is the key for water inrush under the same mining environment, and the circle section column is the most vulnerable section shape of column to water inrush. |
