| 摘 要： | 煤层顶底板突水危险性预测与评价是煤矿突水灾害防治的基础和依据.针对煤层底板隔水介质条件,分析了煤系岩石力学性质,煤层底板变水的岩性、结构和厚度特征,建立了煤层底板突水危险性评价理论和方法.研究表明:煤层底板隔水介质条件取决于隔水层岩性和断裂构造,随着底板泥岩含量增加,煤层底板隔水性能增高,但抗水压能力降低；随着断裂发育...

| Abstract: | Water inrush risk prediction and evaluation of seam roof and floor are the foundation of water inrush disasters prevention in coal mines.According to the waterproof medium conditions of seam floor,the mechanical properties of coal-measure rock and the lithology,structure and thickness of seam floor were analyzed,the theory and methods of water inrush risk evaluation of seam floor were founded.It is shown that the waterproof medium conditions of seam floor depend on the lithlogy of aquifuge and the structure... |
