The formation regimes of veins in fractures of coal

摘要: 根据岩石中裂隙脉的研究方法和理论,对煤中方解石脉的形成机理进行了系统探讨,发现煤中方解石脉以对生式和背生式为主,组合式裂隙脉比较少见。同时,发现了流体压力致裂裂隙的存在,且为多期张裂-闭合作用的结果。

Abstract: According to the theories and methods for the veins in rock, the formation regimes of calcite veins in coals are systematically discussed. It is found that in coals the syntaxial and antitaxial veins are predominant and the composite veins are rare relatively. It is also found that in coals exist the hydrofracturing caused by the crack-seal cycles.
