基于钻孔超声波成像技术的普朗铜矿钻孔节理分布规律研究
|
摘要
对普朗铜矿矿区的四个钻孔开展了超声波成像测井工作,并根据监测数据解译了四个钻孔的结构面的产状、裂隙张开度及钻孔岩体完整性,钻孔超声波监测规律与已有地质编录资料吻合度很好。基于超声波测井技术的钻孔节理分布规律,为普朗铜矿地质、水文地质资料的评价提供了可靠的依据。超声波测井技术在普朗铜矿钻孔节理分布规律测量中得到很好的应用。
Ultrasonic imaging logging work are carried out in the four boreholes of Pulang copper deposit.The shape of the structure,the opening degree of the crack and the integrity of the rock mass can be well interpreted by monitoring data of four boreholes.The regularity of borehole ultrasonic monitoring is in good agreement with the existing geological cataloguing data.The study on the distribution of borehole joints by borehole ultrasonic technology provides a reliable basis for the evaluation of geological and hydrogeological data in Pulang copper deposit.The ultrasonic logging technology is well applied to the measurement of drilling joint distribution in Pulang copper deposit.
