摘要: 缓倾斜中厚至厚矿体的开采一直是采矿界公认的技术难题,针对张家夏楼铁矿地表不允许塌陷且矿体品位低的缓倾斜中厚至厚矿体,提出了采用普通铲运机和遥控铲运机的2种出矿方式的分段空场法。通过技术经济比较,采用遥控铲运机脉内出矿可少掘分段出矿巷道和装矿进路等采准工程,其采切比仅为前者33.9%,吨矿成本降低13.98元,采用底盘沿脉出矿分段空场法技术上可行,经济上合理,值得推荐。

Abstract: Slowly inclined medium thick and thick ore bodies mining has always been a technical problems in the mining industry. The surface of Zhangjiaxialou iron mine is not allowed to collapse and the ore grades is low. According to this situation, the sublevel open stopping method based on ordinary scraper and remote control scraper is proposed. By technical and economic comparison, if the remote control scraper is adopted, some mining engineerings such as sublevel mine roadways and ore loading roadways, the mining-cutting ratio of the remote control scraper is 33.9% of that of ordinary scraper, the cost of tonnage ore is reduced to 13.98 yuan. So the sublevel open stopping method is technically feasible and economically rational.
