复杂难采矿体空场跨度优化设计与采矿实践

Optimal designing of open stoping span of complex ore body and its mining practice

在鸡冠嘴金矿阶段空场嗣后充填采矿试验中，运用模糊数学和数值模拟方法对空场跨度进行优化设计。本文主要介绍了优化设计方法和采矿试验的情况。

In the practical trial of stage open stoping followed by filling in Ji Guan Zui Gold Mine ,the fuzzy mathematic theory and numerical simulation method are used to design the optimal open stoping span.This article briefly introduces optimal designing method and mining experiment.
