底板突水机理研究综述

针对我国煤炭进入深部开采导致底板突水日益严重的现象，系统地介绍了国内外底板突水机理研究历史与现状，阐明了底板突水机理理论研究经过了相对隔水层、突水系数、“下三带”理论、原位张裂与零位破坏理论、板模型理论、强渗通道说、岩水应力关系说、关键层理论、“下四带”理论等发展历程。在阐述各种理论的基本概念基础上，总结和评述了其实际应用价值和理论研究不足之处，指出我国在矿井底板水防治理论研究方面正经历着是一个从实践到理论，再从理论到实践不断发展的过程，同时强调了底板突水机理是一个需要不断深入研究的难题，将非线性理论应用到该领域将是今后发展方向。

Summary of Research on Mechanism of Water-inrush from Seam Floor

In view of the increasingly serious phenomenon of mining the deep coal to cause water-inrush from seam floor in our country,the history and the present situation of research on the mechanism of water-inrush from seam floor at home and abroad is systematically introduced.It clarified the development processes of research on the mechanism of the water-inrush from seam floor,from the floor relative aquiclude,the water-inrush coefficient,the theory of "lower three-zones",the theory of original position tension ...
