香炉山钨矿东部采区点柱回采方案探讨

Discussion on Point Pillar Mining Scheme in Eastern Mining Area of Xianglushan Tungsten Mine

香炉山钨矿东部采区的矿体主要以点柱矿、楼板矿和顶板矿的形式存在,储量大、品位高的点柱矿体是今后东部采区生产的主力,直接关系到矿山稳定和可持续生产。针对点柱的回采提出了围堰式袋装充填采矿法,即先充填空区再进行矿柱回采;针对矿柱的高度和顶板的稳定情况,分别采用不同的回采方式回收矿柱,对矿山生产具有很好的指导意义。

The ore bodies in eastern mining area of Xianglushan Tungsten Mine mainly exist in the form of point pillar ore,floor ore and roof ore.The point pillar ore body with large reserves and high grade will be the main force of production in the eastern mining area in the future,which is directly related to the stability and sustainable production of the mine.The cofferdam-type bag-filling mining method is proposed for the point-pillar mining,that is,the empty area is filled first,and then the pillar mining is carried out.According to the height of the pillar and the stability of the roof,different mining methods are used to recover the pillars,which is instructive to the production of the mine.
