摘要
在安徽霍邱周集铁矿深部普查项目中,采用了数字钻孔摄像技术,并获得了大量铁矿区地质资料。数字钻孔摄像技术形成的钻孔围岩三维立体摄像图像清晰可辨,能够直观识别出铁矿典型区域孔壁,通过优化算法精确计算出结构面产状和隙宽,并划分出优势结构面,确定出结构面的变化规律,与实际岩芯对比基本一致,获取的钻孔信息资料可靠、直观,为深部普查提供了重要参数依据。从中可以得出的结论为:1数字钻孔摄像系统在铁矿深部普查中能够发挥重要作用;2数字钻孔摄像系统能够准确有效地勘测出铁矿钻孔内地质特征;3数字钻孔摄像系统能够划分出优势结构面和确定结构面的变化规律。
Digital borehole camera was adopted in deep exploration of the Zhouji iron ore deposit in Huoqiu, Anhui, and brought a great deal of geological data on the iron ore district. Borehole wallrock 3D image formed by the camera can clearly display borehole wall in typical iron ore district, by optimizing algorithm we can precisely calculate the occurrences of structural surfaces and gap length, divide advantageous structural surfaces and determine the change law of structural surfaces, which is consistent with the real core. So the acquired data is reliable, visualized providing important reference data for deep exploration.
