测井技术在井下出水钻孔水源探查中的应用

Application of Logging Technology in Water Source Exploration of Water bursting Borehole

钻探是煤矿井下预防水害事故发生,保障生产安全的一项重要技术手段,其能够有效探查前方是否含有导水的构造和地质异常体。然而由于地质资料的复杂性和对钻孔轨迹的不确定性,往往无法准确判断出水点的准确位置和出水层位。因此使用一种集视频、岩性判别、轨迹测量为一体的探查技术对煤矿防治水工作尤为重要。以紫晟矿为例,通过利用钻孔测井技术对出水钻孔进行测井,寻找出水点的位置并判断其出水水源。

Drilling is the most effective technical means to effectively distinguish whether there are water-conducting structures and geological anomalies ahead to prevent water disaster and ensure production safety in coal mines.However,due to the complexity of geological data and the uncertainty of borehole trajectory,it is often impossible to accurately determine the exact location of water outlet point and water outlet horizon.The paper introduces an borehole logging technology integrating video,lithology discrimination and trajectory measurement to prevent and control water and find out the position of water producing point and judge its water producing source in Zisheng colliery.
