摘要
黄牛岭铁矿采用组合凿岩嗣后充填采矿法,由于前期开采未重视充填接顶、回采顺序等工作,导致-140m水平采场底部空顶面积大、地压活动频繁等不良现象出现,-140n水平的顶板安全已成为制约矿山安全生产的主要因素,本文通过充填治理采空区、加强支护强度、调整回采顺序、推进减震爆破等方法,有效控制了矿房内的地压显现,并成功摸索出了一套采场分级管控表和管控手段。通过现场实践,探索出了适合本矿山的采场地压管理方法,对类似矿山的地压管理具有指导意义。
The combined rock drilling followed by filling mining method is adopted in huangniuling iron mine.Due to the lack of attention to the filling and roof connection and mining sequence in the early mining,the bad phenomena such as large area of empty roof at the bottom of-140m horizontal stope and frequent ground pressure activities appear.The safety of-140n horizontal roof has become the main factor restricting the safety production of the mine.In this paper,the goaf is controlled by filling Strengthening the support strength,adjusting the mining sequence,promoting shock-absorbing blasting and other methods effectively controlled the low-pressure appearance in the mine room,and successfully explored a set of stope classification control table and control means.Through field practice,the stope ground pressure management method suitable for the mine is explored,which has guiding significance for the ground pressure management of similar mines.
