摘要:

红岭铅锌矿南西翼留有大量矿体、矿柱,以至形成矿体积压,造成资源浪费,对其矿体进行开采具有重要意义。基于采场工作人员的安全、矿山生产能力达标、矿岩稳定性等方面的考虑,提出脉外上向水平分层充填采矿法等4种采矿方法。对比4种采矿方法的优缺点,以及其技术经济指标,最终选择脉内上向水平分层充填采矿法为最佳方法,并进行了现场工业试验。结果表明:该方法的采场生产能力为150 t/d,矿石贫化率和采矿损失率均为6 %,达到矿山的生产能力要求,且有效降低了矿石损失,值得推广。

Abstract:

A large number of ore bodies and pillars are left in southwest wing of Hongling Lead-Zinc Mine,resulting in overstocking of ore bodies and waste of resources.Therefore,it is of great significance to mine these ore bodies.To ensure the safety of workers in stope,the mine production capacity,and the stability of ore rock,4 mining methods were proposed,such as outside-vein upward slicing and filling mining method.After comparing the advantages and disadvantages of the 4 mining methods and their technical and economic indexes,the best mining method was chosen as the in-vein upward horizontal slicing and filling mining method.The field industrial application was conducted,and the results show that the stope production capacity of this method is 150 t/d,the ore dilution rate and the mining loss rate are 6 %,which meet the production capacity requirements of the mine and effectively reduce the ore loss.The method is worth promotion.
