陷落柱突水三维大型模拟实验研究

摘要

In order to study the process ,channel and pressure of water inrush ,we carried out the 3D large‐scale simulation experiment research ,reappeared water inrush of collapse column . The critical water inrush pressure is 0.6 MPa .The position of water inrush of collapse column is at the juncture of roadway and collapse column ,and not at the floor heave of air return roadway . This research provides technical support for experimental research on mechanism of water inrush of collapse column in future ,and the results can provide experimental data for research on water inrush mechanism of collapse .%为了深入研究陷落柱突水过程，确定具体的突水通道和临界突水水压，针对骆驼山煤矿16号煤回风大巷掘进导致陷落柱突水，设计了三维大型模拟实验模型，再现了骆驼山煤矿陷落柱突水的过程。研究得出，回风大巷掘进工作面临界突水水压为0.6 MPa ，突水通道位于陷落柱和巷道迎头处之间，推翻了原来技术人员推测的16煤回风大巷底鼓处的结论。本研究成果可为今后开展陷落柱突水机理实验研究提供技术支撑。
