低沼矿区煤层气体地化特征及其灾害性

CHARACTERISTICS AND DISASTER OF COALBED GAS OF LOW-CONTENT METHANE MINE DISTRICT, CHINA——FOR EXAMPLE OF XUZHOU COAL FIELD

    摘要
  • 摘要: 用立体地球化学的观点和方法研究了徐州煤田“低沼矿区”的瓦斯问题可以获得“低沼矿区”煤层气体是以甲烷为主,重烃含量甚低,δ13C1偏负等特征,并指出:低沼矿区具有相对性的特点,在一定条件下,煤层仍可具一定的气体灾害性。另外,用碳同位素方法还可以判别“煤层气体的活性”,以反映煤层气体和地下水的灾害倾向性。

     

    Abstract: Author applied the theory and methods of gas geochemistry to the coalbed gas research in the mine district with low content methane. The coalbed gas is characted by more methane, little heavy hydrocarbon gas and low negative of δ13C1. etc. Author proposed that the concept of mine district with low-content methane is of relativity. In the condition, the coal seams is also of gas disaster. We can judge "activity of coalbed gas" and fore case the disaster-prone of coalbed gas and underground water.
