摘要
以往通用的钻孔中矿体厚度计算公式存在缺欠。对此，周爱群推导出七种不同情况下的计算公式，虽较严密，但应用亦嫌不便。笔者通过对过去曾介绍用于铅垂钻孔中矿体厚度计算公式ｍ＝（Ｌ＇／ｎ）ｓｉｎθ的研究认为，此公式通用于各种情况。验证对比及应用实例表明此法简便易行且计算结果准确。
Abstract The calculation formula of thicknesses of ore bodies exposed by a borehole used in the past has some shortcomings, for which, Zhou Aiqun offered other seven different formulas. These are tight but aren' t conveniently used. So, having reviewed detailedly on m = (L' / n) sinθ, a previous formula for calculating the orebody thicknesses of a plumb drillhole, the present paper believes that today it still is worthy to be recommended not only in that it can be applied to all types of boreholes but in that it is simple, easy-used and with correct results.
