摘要
在本文中，作者给出关于矿山、矿井或采矿法的三级矿量保有量和保有期的明确概念，提出在各个矿块尺寸都相同和前进式开采条件下计算三级矿石保有量和保有期限的公式．在其它条件这些公式起基础作用，还对计算三级矿石保有量和保有期的不正确的公式和态度很出意见。
In this paper, authors give clear concepts about remain quantity and remain period of ore of threegrades,which is in possession of mine or mining method, advance calculating formulas of remain quan-tity and remain period when every block has same size and direction of mining is advancing, under oth-er conditions these formulas play basic role, and critisize erroneous calculation formulas and attitude.
