北辛窑煤矿南翼大巷突水机理研究

Study on Water Inrush Mechanism of the South Wing Roadway in Beixinyao Coal Mine

北辛窑煤矿发生多次涌水事故,为煤矿生产建设造成一定的经济损失。本文以该矿南翼大巷突水事故为研究对象,分析涌水情况特征,并利用地质分析与地球化学分析方法对奥灰水钻孔水质和突水机理进行分析,判断南翼大巷突水水源为奥灰水,为下一步采取防治水措施提供了参考依据。

This paper takes the water inrush accident in the south wing roadway of Beixinyao Coal Mine as the research object,analyses the characteristics of water inrush,and uses geological and geochemical analysis methods to analyze the water quality and water inrush mechanism of boreholes,and judges that the water inrush source of the south wing roadway is ordovician limestone water,which provides a reference basis for further water prevention measures.
