摘要
在自然崩落法中最佳放矿高度的研究旨在准确计算可采矿量,并根据每个放矿点的经济价值来调整放矿点的布置并进行放矿点布置的优化。针对目前国内自然崩落法按照原地质品位估算每个放矿柱体高度的不准确问题,对放矿过程中矿石的流动进行分析,运用混合算法对放矿柱体进行预先混合,求解混合后各分层品位,提出了最佳放矿高度的计算模型,解决了按原地品位计算最佳放矿高度不准确的问题。
The research of optimal drawing height in block caving method was intended to accurately calculate the economic ore reserves, and the layout of drawing points was adjusted and optimized based on the economic value of each drawing point. According to the inaccurate problem of each ore-drawing column height estimated by original geological grade in block caving method in China, the flow characteristic of ore during drawing was analyzed. The drawing column was premixed by hybrid algorithm. After that, the grade of each layer was calculated. And the calculating model of optimal drawing height was put forward, which solved the inaccurate problem.
