基于3D-σ对云锡卡房锡矿13-2矿体回采方案研究OA
Study on 3D-σ for the 13-2 Ore Body in the Tin Mine of Yunxi - Tin
介绍了矿体回采顺序对矿体稳定性的重要影响,并介绍了研究矿山回采顺序的几种方法,通过3D-σ软件对卡房13-2矿体253~254线矿体回采方案、采矿方法、采场结构参数及回采顺序的数值模拟研究分析,发现针对卡房分矿13-2矿体花岗岩倒转部分的矿体,由于花岗岩揭露后容易风华,稳定性较差,采用空场法进行开采无法满足安全要求.卡房13-2花岗岩倒转部分矿体,采用进路式胶结充填能减少顶板及围岩的变形,但采用隔三采一效果要好于隔一采一.13-2矿体253~25…查看全部>>
In this paper, the important influence of orebody stoping sequence on the orebodystability is introduced,and several methodsof researching mining stoping sequence are introduced. After researching and analyzing the numerical modeling of recovery plan, mining method and stope structure parameters and stoping sequence of the card room 13-2 orebody 253 ~ 254 line orebody with 3D- sigma software, we found the card room points of 13-2 orebody granite revers…查看全部>>
