| 摘 要： | 钻孔孔径变化与矿床类型、钻进孔径、矿化岩性、矿层品位、矿层厚度、冲冼液的性质以及工程切穿矿层的时间有着密切的关系。孔径变化对γ测井解释含量、矿床储量的增减影响甚大。理论和实践证明,专门性的孔径测量,是提高γ测井质量、准确确定矿层品级的重要措施之一,对提高矿床经济效益也具有重要意义。

| Abstract: | There is some closer relation between variations in hole diameters and ore deposit type, hole diameters mineralized rock, ore grade and thickness, feature of washing liquor, as well as the time that ore body is intersected by drill holes, The variations in hole diameters would largely affect on explaining uranium content in gamma-logging and the ore reserves estimation. The theory and practice proved that the special diameter survey is one of the important measures for improving the quality of gamma-logging to determine the ore grade exactly. In addition, it is also of some significance for increasing the economic benefit of uranium deposits. |
