| 摘 要： | 因煤矿突水中大部分突水是与断层破裂带有关,应用隔水关键层原理分析断层突水机理是非常有必要的.首先根据断层的形成机理及其位置分析了断层突水的原因,探讨了煤层断层的突水条件;然后基于隔水关键层原理建立了含隔水断层的隔水关键层活化力学模型,理论解析了隔水断层在矿压和水压作用下的断层活化滑移条件,最后分析了顶、底板隔水断层的断层活化突水机理,得出了在矿压和水压共同作用下的断层采动活化突水条件.

| Abstract: | Because most of the water-inrushes in coal mine are related to the faulted zone,it is very necessary for us to analyze fault water-inrush mechanism based on the principle of water-resisting key strata.First of all,according to the fault formation mechanism and the fault position,we analyzed reason of the fault water-inrushing and discussed water-inrush condition of the coal seam.Then,based on the principle of water-resisting key strata,the mechanical model of fault activating is established for the water-re... |
