某采场上向水平分层进路充填采矿法结构参数研究

Structure Parameter Study of Upward Horizontal Sub-level Drift Fill Stoping Method of one Stope

上向水平分层进路充填采矿法采场结构参数越大,回采效率越高,但过大的结构参数使采场稳定性难以保证,该方法采场结构参数优化的重点应集中于进路断面尺寸的优选。通过经数值模拟和Mathews稳定性图解法分析,从经济、合理开采资源方面出发,最终推荐进路断面尺寸。

When the structure parameters of upward horizontal sub-level drift fill stoping methods are bigger,the stoping efficiency is higher,but the stope stability can not be guaranteed because of the excessively large structure parameters,the optimization focus of stope structure parameters shall be on the selection of drift cross-sectional dimension.The numerical simulation and Mathews stability graphical analysis were carried out from the aspects of the economy,rational exploitation of resources,and the drift cross-sectional dimension was recommended finally.
