摘      要：This paper analyzes the basic characters of optimum open-pit limit. According to them, following general rule for designing pit limit is obtained. The incremental stripping ratios is not greater than the break-even stripping ratios, or the net incremental value is not less than zero. The rule can be used both in traditional and computer methods as direct basis to determine an optimum limit for any kinds of deposit.

主 题 词：open-pit limit optimum design incremental stripping ratios incremental package, net incremental value
