在岩石全应力应变伺服渗透试验的基础上,提出了岩石膨胀界限抗渗强度的概念,并在此基础上建立了底板突水评价模型,模型考虑了底板岩层有效隔水层厚度、岩性、岩体完整程度以及膨胀界限抗渗强度并详细分析了各参数的取值,以兖矿集团杨村煤矿17煤及其2702工作面突水评价为例,证实了以膨胀界限抗渗强度为基础的底板突水评价模型在突水评价上具有可行性。
Based on the rock full stress and strain servo penetration test, the concept of seepage resistance of rock expansion limit was put forward. Based on this, a model of floor water inrush was established. The model considered the thickness of the effective aquitard, the lithology, The complete degree of rock mass and the anti-seepage strength at the expansion limit, and the values of each parameter are analyzed in detail. Taking the water inrush of No. 17 coal and its 2702 face of Yangcun Coal Mine of Yankuang Group as an example, it is confirmed that based on the infiltration limit strength The model of inrush water inrush evaluation is feasible in water inrush evaluation.
