摘要
矿床赋存于高破碎覆岩条件下时,采用有底柱分段崩落法采矿方法,容易造成出矿时提前贫化、矿石回收率低等问题。本文提出利用注浆和放矿控制的手段,对此类工程地质条件下的矿床进行治理,并结合工程实际分析研究。
It is likely to cause the ore dilution in advance and low ore recovery problems when adopting the sublevel caving mining method at the case of the deposit under the condition of high broken strata. This paper use the grouting and ore control method to study the management scheme that the deposit under this kind of engineering geological conditions and then analysis it combined with engineering practice.
