THE EFFECT OF DEPOSITIONAL ENVIRONMENTS ON THE STRENGTH OF ROCKS IN COAL MEASURES

    摘要
  • 摘要: 分析了平顶山矿区煤系中形成于不同沉积环境的64组岩石样品的沉积特征和强度,结果表明,岩体的强度与沉积环境有着密切的成因联系。岩体强度的变化主要受控于岩性、沉积环境中能量的高低、水动力条件的变化幅度和生物发育程度4项因素。

     

    Abstract: This paper focuses on the analysis of mechanical properties of 64 rock samples collected from Permo-Carboniferous Coal Measures, Pingdingshan,Henan Province.The work reveals that the strength of rocks closely relates to the depositional environments in which the rocks were deposited.The strength of rocks is mainly dependent on （1）lithologic character; （2）hydraulic energy;（3）fluctuating features of hydraulic conditions; and （4）biological activity in the depositional environments.
