关于完善本溪铀矿采矿方法的探讨

THE IMPROVEMENT ON THE MINING METHOD IN BENXI URANIUM MINE

总结了本溪铀矿近几年采矿的生产情况及存在的问题,据此,对适应该矿山地质条件的几种采矿方法进行了技术分析。论证了水平分层充填采矿方法在技术上的可行性,经济上的合理性。提出了采用上述采矿方法的具体方案;针对围岩不稳定的特点,提出了固结围岩的几种方案;为确保采矿安全,减少采场空顶时间,采用了“强采快充”方法,并提出了快速充填具体办法。文中的一些方案已在现场得到应用。

In this paper,presents a concluded mining situation and existed problem in Benxi Uranium Mine in recent years.According to these,a technical analysis of several mining method is technically possible and economically reasonable.In order to improve this mining method,several reinforcements of surrounding rock are presented.It is proposed to decrease exposure time of mining excavation to minimum and fill the excavation quickly using new filling method for security.Some proposed plans have been applied on site,the others will be helpful to the later operation of the project.
