| 底板变形破坏是煤层底板突水的重要影响因素，借助室内试验系统进行相似材料模拟研究是获取深部采动条件下底板突水灾变演化及防治的有效手段。文章总结了相似材料模拟在煤层底板变形破坏中的应用原理、相似材料选择及模型制作，综述了试验相关理论、试验材料、试验装置研制以及量测技术与成果分析等方面的研究进展，重点分析了目前存在的主要问题。最后，指出在未来的研究中，需在模型材料、新技术、新方法方面加强攻关，且应注意相似材料模拟、理论计算、数值模拟和现场实测等多种方法的综合应用，进而综合确定煤层底板的变形破坏情况。 |
| 英文摘要: |
| Deformation and failure of coal seam floor is the key factor affecting floor water inrush. Similar material simulation research in laboratory is an effective measure to learn the disaster evolution and prevention of floor water inrush under deep mining conditions. This paper summarizes the application principle,selection of similar materials and model making of similar material simulation in the deformation and failure of coal seam floor. Then the relevant research achievement is reviewed, including the theories, experiment materials,experiment apparatus design,measurement technique and result analysis, and etc, where the main present problems are analyzed as the focus. Finally, it is pointed out that the mode material, new technologies and methods should be given the first place in the future research. Moreover,attention should be paid to the comprehensive application of similar material simulation,theoretical calculation,numerical simulation and field measurement, and then the deformation and failure of coal seam floor is determined with a holistic approach. |
