国外某有色金属矿山开采技术方案综合优化

Techno-economic optimization of an overseas underground non-ferr ous metal mine

为进一步改善项目效益指标,对矿山原推荐的技术方案进行了系统优化。通过对原报告推荐的斜坡道开拓系统、分段空场嗣后充填采矿法、无轨卡车运输及相应通风系统、疏干排水系统分散建设方案进行系统分析后,综合优化调整为竖井开拓系统、上向水平分层充填采矿法、有轨运输、多维协同疏干系统。经测算,优化后的项目效益指标取得了大幅改观。

In order to further improve the project financial index,the original recommended technical solutions of the mine was systematically optimized.After systematic analysis of the decline system,sublevel open stope with backfilling mining method,trackless truck transportation and the corresponding ventilation system,and the multiple construction plan of the dewatering system recommended in the original report,comprehensive optimization and adjustment were made to the vertical shaft system and cut and fill mining method,locomotive track transportation,multi-dimensional synergistically dewatering system.After evaluation,the optimized project financial indicators have been greatly improved.
