陷落柱及其赋水性的正演模拟研究

煤矿中的陷落柱一直制约着煤矿的安全生产。为了有效识别陷落柱，以山西矿区岩溶陷落柱为例，利用地震数值模拟和电法数值模拟方法，探讨了陷落柱地震响应及赋水特征。通过建立陷落柱模型，模拟得出陷落柱在地震上响应存在明显的绕射波特征及赋水性陷落柱“两高夹一低”的特征。

Study on Forward Modeling of Collapse Column and Its Water Bearing Property

Collapse column in coal mine has been restricts the safe production of coal mine. To effectively identify collapse column and improve the understanding of collapse column，we make karst collapse column in mining area in Shanxi Province as an example. The method of seismic numerical modeling and numerical simulation method were used to discusses the seismic responses of the collapsing column and water features. In this paper，through the establishment of collapse column model，the authors simulated the collapse column on the earthquake response of obvious diffraction potter character and assign water of collapse column "projects clip one low" characteristics.
